"Litter Production and Decomposition Rate in the Reclaimed Mined Land under Albizia and Sesbania Stands and Their Effects on some Soil Chemical Properties."

Vegetation establishment is considered as a critical step of mined land rehabilitation. The growing plants do not only prevent soil erosion, but also play important roles in soil ecosystem development. Their litterfall is the main process of transferring organic matter and nutrients from aboveground tree biomass to soil. Thus, its quantification would aid in understanding biomass and nutrient dynamics of the ecosystem. This study was aimed to investigate the litter production and its decomposition rate in a reclaimed mined land using albizia and sesbania, and theireffects on some soil properties. The litter under each stand was biweekly collected for four months. At the same time litter samples were decomposed in mesh nylon bags in soils and the remaining litters were biweekly measured. Soil samples were taken from 0-15 cm depths from each stand for analyses of soil organic C, total N, and cation exchange capacity (CEC). The results demonstrated that total litter production under albizia (10.58 t ha-1 yr-1) was almost twice as much as that under sesbania stands (5.43 t ha-1 yr-1). Albizia litter was dominated by leaf litter (49.26%) and least as understory vegetation (23.31%), whereas sesbania litter was more evenly distributed among litter types. Decomposition rates of all litters were fastest in the initial stage and then gradually decreased. Sesbania leaf litters decomposed fastest, while albizia twigs slowest. Differences in the litter production and decomposition rates of the two species had not sufficiently caused significant effects on organic-C, total N, and CEC of the soilsafter one year of revegetation.Keywords: Albizia (Paraserianthes falcataria), decomposition rates, litter, mined land, Sesbania grandiflora

Abstract. Litters of reproductive organs have rarely been studied despite their role in allocating nutrients for offspring reproduction. This study determines the mechanism through which flower litters efficiently increase the available soil nutrient pool. Field experiments were conducted to collect plant litters and calculate biomass production in an alpine meadow of the eastern Tibetan Plateau. C, N, P, lignin, cellulose content, and their relevant ratios of litters were analyzed to identify their decomposition features. A pot experiment was performed to determine the effects of litter addition on the soil nutrition pool by comparing the treated and control samples. The litter-bag method was used to verify decomposition rates. The flower litters of phanerophyte plants were comparable with non-flower litters. Biomass partitioning of other herbaceous species accounted for 10–40 % of the aboveground biomass. Flower litter possessed significantly higher N and P levels but less C ∕ N, N ∕ P, lignin ∕ N, and lignin and cellulose concentrations than leaf litter. The litter-bag experiment confirmed that the flower litters of Rhododendron przewalskii and Meconopsis integrifolia decompose approximately 3 times faster than mixed litters within 50 days. Pot experiment findings indicated that flower litter addition significantly increased the available nutrient pool and soil microbial productivity. The time of litter fall significantly influenced soil available N and P, and soil microbial biomass. Flower litters fed the soil nutrition pool and influenced nutrition cycling in alpine ecosystems more efficiently because of their non-ignorable production, faster decomposition rate, and higher nutrient contents compared with non-flower litters. The underlying mechanism can enrich nutrients, which return to the soil, and non-structural carbohydrates, which feed and enhance the transitions of soil microorganisms.

Full textAbstract:
Litter production and decomposition are important in nutrient cycling and detritus based food chain. Litter production in mangrove varies widely with species, forest type, stand age, geographical location and environmental parameters (e.g. rainfall, temperature, wind). Higher rate of litter production is observed at the lower latitudes (tropical region) and it decreases linearly with increasing latitude (sub-tropical region). Decomposition of leaf litter is characterized by an initial leaching of soluble organic and inorganic compounds with subsequent colonization by micro-organisms, which initiates physical and biological fragmentation of plant material. Litter degradation rate varies with species, geographical location, degree and frequency of tidal inundation, climatic and edaphic factors and presence of litter consuming fauna in the mangrove forest. In mangroves, higher rate of microbial decomposition of litter is observed in litter with lower content of tannin and leaves with thin cuticle, wet season and lower tidal inundation classes.

Full textAbstract:
Production, decomposition, and release of nutrients from leaf and nonleaf litter were investigated in four subalpine forests of North-West Himalaya, India. Total annual litter fall in four communities varied from 2950.00 to 4040.00 kg ha−1 and was found significant (CD0.05 = 118.2). Decomposition of leaf litter varied from 1.82–3.5% during autumn-winter to 36.14–45.51 during summer rainy season in all stands and percent of mass loss was significantly varied in stands (CD6.00). Similarly, decomposition in nonleaf litter was varied from 0.3–1.1% during autumn-winter to 19.59–30.05% during summer rainy season and was significantly varied irrespective of seasons. However, percent decomposition of leaf litter and the values of decay constant (k) were at par in all stands. Total standing state of nutrients in fresh litter as well as release of total nitrogen (N), phosphorus (P), and potassium (K) in due course of decomposition (12 months) was also varying significantly. The rate of nonleaf litter decomposition was significantly positively correlated with air temperature (r=0.63–0.74 in all communities). The significant correlation (r=0.85) was observed only in Rhododendron-Sorbus forest community (PRS). Study indicates that the air temperature is a major determinant for nonleaf litter decomposition in this region.

Mangrove vegetation growsalong the coastal line and iscapable of thriving in salty water. Therefore, the study reported in this articlesought to describe the production and decomposition rate of Ceriops tagal litter in Tanjung Panjang Nature Reserve in Randangan Sub-District, Pohuwato District, Gorontalo Province. A survey method was employed, and a purposive sampling technique was used for selecting the research site. The data of litter production was collected using a litter trap of 2m x 1m. Decomposition data was collected using a litter bag sized of 1m x 1m. The results showed that litter production containing leaves at Station I reached 46%, twigs 40%, and fruits 14%. At Station II, the production of litter containing leaves reached 42%, twigs 45%, and fruits 13%. At Station III, the production of litter containing leaves reached 48%, twigs 43%, and fruits 9%. The decomposition rate (R) of C. tagal litter at each station was obtained with an average on the 14th day of 0.42 g, 0.75 g, and 0.77 g, respectively. On the 28th day, it was 0.75 g, 1.00 g, and 0.89 g; on the 42nd day was 1.13 g, 1.27 g, and 1.22 g; and on the 56th day was 1.48 g, 1.62 g, and 1.59 g. The ratio of the decomposition rate of C. tagal litter on day 14 to day 56 increased. This condition was influenced by several environmental factors, including salinity, which ranged from 4.5-6.3‰, ambient temperature at 27-28°C, dissolved oxygen at 2.0-5.0 mg/L, and soil pH between 5.9-8.0.Keywords: Ceriops tagal, decomposition rate, litter production, Pohuwato

Litter decomposition makes possible the nutrient cycling and is a link between vegetation and soil, vital for a healthy forest ecosystem. Although several studies on litter decomposition have been carried out in different regions of Brazil, there are few studies for transitional zones between Cerrado and Caatinga, particularly in the state of Piauí. Therefore, the objective of this work was to evaluate the litterfall production, litter composition and decomposition rate in a tropical dry forest fragment located in the southeast region of Piauí, Brazil. Monthly litterfall dynamics were evaluated for one year, by placing litter traps in the center of six forest inventory permanent sample plots, and the decomposition rate was determined by the litterbag technique. Litterfall production was estimated at 4,401.7 kg ha-1 year-1, similar to Caatinga environment values, with the leaves fraction contributing with the highest percentage (64%). On the other hand, litter decomposition rate was estimated at 0.003 g day-1, similar to rates found in Cerrado environments, highlighting the importance to better understand this ecozone litter dynamics. Wind speed had significative correlation with litterfall production. The number of species in the sample plot had highest correlation with the decomposition rate, and the diameter growth rate was the dendrometric variable most correlated to litterfall production.

Full textAbstract:
Land-use change, including tropical deforestation for agriculture and subsequent agricultural abandonment, may change the stoichiometry of nutrient cycling in tropical secondary forests relative to mature forests. While phosphorus (P) is conservatively cycled in these mature forests, nitrogen (N) losses during an agricultural phase may provoke conservative N cycling processes in young secondary forests. Here we explore differences in nutrient cycling properties among secondary and mature forests of the eastern Amazon, including litter nutrient concentrations and rates of litter production and decomposition. In a chronosequence of successional forest age, N production in litterfall and N loss during litter decomposition were low in young forests but increased with increasing forest age, whereas P was conservatively cycled in all forest ages. Litter N concentration was positively correlated with the rate of mass loss in a litterbag study and with a mass balance estimate of litter decomposition based on annual litterfall and litter stock measurements. Therefore, while P is conservatively cycled and may limit or co-limit productivity in these forests, variation in N content of litter among forest successional stages may be related to differences in decomposition rates and mean residence times of litter, thus linking N availability with rates of litter decomposition and P cycling.

ABSTRACT Mangrove litter leaf represent the organic substance supplier towards fertility of mangrove ecosystem, that able to support the mortal life within. The area of forest of mangrove represent the nursery ground, feeding ground, and area of spawning ground for various fish type, prawn and other biota sea and also as producer of amount of detritus for plankton as main foods source of the sea. The objectives of this research were to know production and decomposition rate of mangrove litter leaf in the mangrove ecosystem of Durian Village and Batu Menyan Village, Padang Cermin subdistrict, Pesawaran regency. Data was analysed by calculating the dry weight mean of litter leaf production and to counting decomposition rate was using the exponential rank function or from absolute decomposition percentage of litter leaf per day. This research was conducted in two place (station) based on the difference of substrate characteristic. The research conducted from October to December 2013. The productivity of mangrove’s litter leaf in both places is 0,56 g/m2/day, where the leaf organ gave the higgest contribution, (66%), stick and branch (14%), flower and fruit (20%). Decomposition rate of mangrove litter leaf showed that at the second station ( 0,20 g / hr) was faster than the first station ( 0,19 g / hr).

While Si influences nutrient stoichiometry and decomposition of graminoid litter, it is still unclear how Si influences anoxic litter decomposition and CH4 formation in graminoid dominated fen peatlands. First, Eriophorum vaginatum plants were grown under different Si and P availabilities, then shoots and roots were characterized regarding their proportions of C, Si, N and P and regarding C quality. Subsequently the Eriophorum shoots were subjected to anoxic decomposition. We hypothesized; that (I) litter grown under high Si availability would show a higher Si but lower nutrient mass fractions and a lower share of recalcitrant carbon moieties; (II) high-Si litter would show higher CH4 and CO2 production rates during anoxic decomposition; (III) methanogenesis would occur earlier in less recalcitrant high-Si litter, compared to low-Si litter. We found a higher Si mass fraction that coincides with a general decrease in C and N mass fractions and decreased share of recalcitrant organic moieties. For high-Si litter, the CH4 production rate was higher, but there was no long-term influence on the CO2 production rate. More labile high-Si litter and a differential response in nutrient stoichiometry led to faster onset of methanogenesis. This may have important implications for our understanding of anaerobic carbon turnover in graminoid-rich fens.

Litter production was evaluated in successional pine-oak forests in two localities in Chiapas; simultaneously we assessed the leaf-litter decomposition of seven tree species ( <em>Alnus acuminata subsp. arguta, Chiranthodendron pentadactylon, Clethra suaveolens, Liquidambar styracifl ua, Quercus crassifolia, Quercus sapotifolia and Pinus oocarpa </em>). After 1-year, the highest litter production was recorded in pine-oak-forests (7.59±0.29 Mg·ha-1·year-1), followed by the oak forests (6.58±0.27 Mg·ha-1·year-1), pineoak-Liquidambar forests (5.33±0.18 Mg·ha-1·year-1), pine forest (5.18±0.19 Mg·ha-1·year-1), and the lowest annual litter production occurred in the plots under forest restoration (2.43±0.13 Mg·ha-1·year-1). After 10-mo, the highest rate of leaf-litter decomposition occurred in <em>Alnus acuminata </em> (61-67%) regardless of the forest conditions and in the rest of the species, litter decomposition ranged from 34-52%, but not signifi cant differences between forest conditions were observed.

Abstract Peat swamp forest is an important ecosystem in global climate change through its high carbon content and role as a carbon sink. In peat swamp forest, there is a near-closed cycle of nutrients including carbon. In order to better understand the rate of plant litter production and decomposition, a study was carried out in three secondary peat swamp forests in Central Kalimantan, Indonesia. Litterfall collection was undertaken using a litter trap with samples collected every month in the first year and every two months thereafter between June 2018 and June 2021. The rate of litter decomposition was assessed by measuring the reduction in dry weight of litter at 3, 6, 12 and 24 months. At each of three study sites, two sets of recently fallen litterfall were placed in 25cm x 25cm mesh bags on the peat soil surface to assess decomposition rates under aerobic conditions, and another two sets of litter were placed at a depth of 40 cm to assess decomposition rates under anaerobic conditions. Dry weight of fresh litterfall and decomposed litter samples was determined at 3, 6, 12 and 24 months, and total carbon content was analyzed using the loss of ignition method. The results showed that litterfall production in secondary peat swamp forests was about 9.52 ± 3.57 t ha−1 and it followed a seasonal pattern, with higher production in the dry season. The rate of litter decomposition was exponential and faster under aerobic conditions.

Invasive Acacia species can alter nutrient cycling processes in forest ecosystems, particularly affecting total litterfall production and litter decomposition patterns. This study examined the effects of exotic Acacia mangium Willd. on total litterfall production, nutrient concentrations in leaf litterfall fractions, leaf litter decomposition, and nutrient release in lowland heath (HF) and mixed dipterocarp forests (MDF) in Brunei Darussalam, Borneo. Above-ground litterfall traps were installed in HF and MDF with and without invasive Acacia present, representing four habitat types in total, and monthly collections were conducted for 12 months. Litter decomposition bags were deployed to determine the rates of decomposition and nutrient release. Habitats invaded by Acacia exhibited higher total litterfall production, increased leaf litter concentrations of nitrogen, potassium, and calcium, and increased addition of all nutrients measured in litter (nitrogen, phosphorus, potassium, calcium, and magnesium, especially in the Acacia-invaded mixed dipterocarp forest (AMDF) and nitrogen and potassium in Acacia-invaded heath forest (AHF)), reduced nitrogen and potassium use efficiencies in AHF, and reduced stand-level nitrogen and calcium use efficiencies in AMDF. Litter decomposition rates and nutrient release were lower in AMDF than in the three other habitats. The significantly higher total litterfall production coupled with higher nutrient addition in the two Acacia-invaded habitats is expected to progressively increase the abilities of these habitats to produce large quantities of nutrient-rich litter and will likely eventually lead to an enrichment of nutrients in the soil, thus facilitating further invasion by Acacia, particularly in the MDF.

The ecosystem processes in the caatinga, such as litter dynamic, are threatened and little is known about it in these environments. The litter processes can be used as indicators of degradation or recovery of an ecosystem because these processes react to changes in the ecosystems. The litterfall deposition was collected monthly over 23 months in collectors of 1.0 m2. The litter accumulation on soil was collected monthly over 23 months in frames of 0.25 m2. The coefficient of decomposition (K) was estimated by the relation between annual litter production and litter stock in the soil surface. Annual litterfall production increased with stand age. Total annual litter production in different age stands varies from 1.37 Mg ha-1 in the 15 years to 2.37 Mg ha-1 in the 50 years stand. K and renewal times were also significantly different among the sites. K was higher in 50 years, followed by 30 years and 15 years. There were a higher litter production and accumulation in the older stands. The older stands presented faster litter decomposition and renew, which evidences a better utilization of litter in the nutrient cycling process and the incorporation of organic matter into the soil. These results show that litter processes are effective indicators of the stage of degradation in a caatinga ecosystem.

Abstract Backgrounds and aims Litter protects the underlying soil, depending on litterfall and decomposition, but dynamics of the standing litter stock in agroforestry systems remain poorly understood. We aimed to unravel effects of litter quality, temporal patterns, microclimate, and a possible home-field advantage (HFA) on standing litter dynamics across a land-use gradient. Methods We quantified litterfall, the standing litter stock, and microclimate during a year in (remnant) forest, cacao-based simple and complex agroforestry, cacao monocultures, and annual crops in a cacao producing area in Indonesia. We conducted a reciprocal litter transfer experiment, and tested decomposition rates of pruning residues. Standing litter stocks during the year were estimated from monthly litterfall and decomposition rates. Results Variation in litter quality influenced decomposition rates more strongly than variation in microclimate or HFA. Lower litter quality in complex agroforestry and in the cacao monoculture decreased the decay rate compared to simple agroforestry systems; mean litter residence time was over a year. Mixing high- and low-quality material in pruning residues modified the decomposition rate, soil C and N changes, offering options for targeted management of soil protection and nutrient release. Conclusions The seasonal patterns of litterfall and relatively slow decomposition rates supported permanence of the litter layer in all cacao production systems, protecting the underlying soil.

Considering the importance of nutrient cycling as an indicator in the maintenance of the ecosystem productivity, the present study aimed to assess the seasonal dynamics of production and decomposition rate of litter in a fragment of Cerrado sensu stricto. The litter collections were carried out monthly from june 2016 to may 2017, after which the leaves, branches and reproductive material were separated. The litter decomposition was evaluated using the litter bags method, with a random distribution of 288 litter bags. The annual production of litterfall was quantified in 6.042,50 kg.ha-1.yr-1, in which the leaf prevalent fraction presented a production of 4.644,40 kg.ha-1.yr-1, then, the fractions branches (1.084,10 kg.ha-1.yr-1) and reproductive material (329,90 kg.ha-1.yr-1). The litterfall obtained higher production in july with 1.464,00 kg.ha-1 and lower production in the month of December (138,70 kg.ha-1). A significant negative correlation was observed between litterfall and its fractions with the precipitation and relative humidity. The decomposition of foliar mass reached 49% and 50% of twigs during the nine-month period, in which the decomposition constant (k) for leaf mass and for branches was 0.0030g g-1day-1. For this constant, the estimate for the disappearance of total mass has been estimated to be 1.000 days (29 months). The breakdown proved to be slow for both leaves and branches thus obtaining the value of the constant of decomposition 0.0030g g-1 day-1for both.

Full textAbstract:
Plant litter decomposition is critical for terrestrial ecosystem productivity. Poa ligularis Nees ex Steud and Nassella tenuis (Phil.) Barkworth are native, desirable perennial grasses in central Argentina’s rangelands. Amelichloa ambigua (Speg.) Arriaga & Barkworth is only consumed when a better forage is unavailable. Litter traps were used to collect aboveground litter during two years. In March 2012, six bags, each one containing either leaf blade (three bags, one per species) or root litter (three bags, one per species) of the three species were located below the canopy of each replicate plant of the studied species (hereafter referred to as ‘location’). Blade litter bags were located on the soil surface, and root litter bags buried at 10cm soil depth. This allowed evaluation of the effects of defoliation, the different species canopies and the microbial community activity around their roots on decomposition of above- and belowground litter. For each species, twenty plants were either defoliated twice (5cm stubble height) or remained undefoliated during the growing season. Litter bags were collected after 2, 7, 13 and 24 months incubation. The study was repeated in 2013, with additional bags were placed for N content determination on leaf blade and root litters. Aboveground litter production was highest in P. ligularis; however, no differences were observed among species when the effect of plant size was eliminated. Aboveground litter of desirable species had higher N content and decomposed faster than that of A. ambigua. The opposite was recorded for root litter. Defoliation had no effect on litter decomposition, but location effects were detected after one year of incubation. Desirable perennial grasses promoted organic matter loss from litter, a key factor in increasing soil fertility in this semiarid ecosystem.

Land degradation is the result of soil mismanagement that reduces soil productivity and environmental services. An alternative to improve degraded soils through reactivation of biogeochemical nutrient cycles (via litter production and decomposition) is the establishment of active restoration models using new forestry plantations, agroforestry, and silvopastoral systems. On the other hand, passive models of restoration consist of promoting natural successional processes with native plants. The objective in this review is to discuss the role of litter production and decomposition as a key strategy to reactivate biogeochemical nutrient cycles and thus improve soil quality in degraded land of the tropics. For this purpose the results of different projects of land restoration in Colombia are presented based on the dynamics of litter production, nutrient content, and decomposition. The results indicate that in only 6–13 years it is possible to detect soil properties improvements due to litter fall and decomposition. Despite that, low soil nutrient availability, particularly of N and P, seems to be major constraint to reclamation of these fragile ecosystems.

In cranberry production systems, stands are covered by 1–5 cm of sand every 2–5 years to stimulate plant growth, resulting in alternate layers of sand and litter in soil upper layers. However, almost intact twigs and leaves remain in subsurface layers, indicating a slow decomposition rate. The Tea Bag Index (TBI) provides an internationally standardized methodology to compare litter decomposition rates (k) and stabilization (S) among terrestrial ecosystems. However, TBI parameters may be altered by time-dependent changes in the contact between litter and their immediate environment. The aims of this study were to determine the TBI of cranberry agroecosystems and compare it to the TBI of other terrestrial ecosystems. Litters were standardized green tea, standardized rooibos tea, and cranberry residues collected on the plantation floor. Litter decomposition was monitored during two consecutive years. Added N did not affect TBI parameters (k and S) due to possible N leaching and strong acidic soil condition. Decomposition rates (k) averaged (mean ± SD) 9.7 × 10−3 day−1 ± 1.6 × 10−3 for green tea, 3.3 × 10−3 day−1 ± 0.8 × 10−5 for rooibos tea, and 0.4 × 10−3 day−1 ± 0.86 × 10−3 for cranberry residues due to large differences in biochemical composition and tissue structure. The TBI decomposition rate (k) was 0.006 day−1 ± 0.002 in the low range among terrestrial ecosystems, and the stabilization factor (S) was 0.28 ± 0.08, indicating high potential for carbon accumulation in cranberry agroecosystems. Decomposition rates of tea litters were reduced by fractal coefficients of 0.6 for green tea and 0.4 for rooibos tea, indicating protection mechanisms building up with time in the tea bags. While the computation of the TBI stabilization factor may be biased because the green tea was not fully decomposed, fractal kinetics could be used as additional index to compare agroecosystems.

Full textAbstract:
This study aimed to evaluate the relative importance of the factors whereby tree species composition can influence leaf litter dynamics. Leaf litter production and chemical composition were measured in pure and mixed stands of oak ( Quercus petraea Liebl.) and beech ( Fagus sylvatica L.). Pure and mixed leaf litter of both species were incubated in each stand type to assess separately the environmental, litter quality, and litter mixture effects on decomposition. To better understand the environmental effects, ground climate was measured in the different stands and the effects of soil water content on decomposition were evaluated using roofs to simulate drought conditions. Although total leaf litter amounts were not affected by stand composition, leaf decomposition varied with litter quality and with the environmental conditions. In the same environment, oak leaf litter disappeared on average 1.7 times faster than beech leaf litter. Decomposition of oak leaves increased significantly in the mixed-species litterbags. In contrast, the overall mass loss of the mixed litter tallied with the mass loss estimated by examining the decomposition of the component litter separately (additive-effect hypothesis). The effects of stand type appeared in the third year of incubation: leaf mass loss of both species was greater in the beech stand. In addition, soil water content affected leaf decomposition: the oak and beach leaf mass losses dropped by 24% and 17%, respectively, in the dry modality.

Chemical changes in leaf input to forest soils have been reported to affect decay processes. In this work, litter mass loss and decomposition constants (k) during 200 days in solid-state fermentation of the native tree Celtis tala Gill. ex Planch. and the exotic one Ligustrum lucidum Ait. with three common litter saprotrophic basidiomycetes were compared. Alterations in litter quality were characterized by solid-state13C NMR spectroscopy, pH, soluble sugars, ammonium, proteins, and phenol content determination and were associated with extracellular lignocellulolytic enzyme production. Differences in substrate decomposition related to litter type were observed for Leratiomyces ceres, achieving a higher k in the exotic L. lucidum litter, which might be attributed to the induction of manganese peroxidase activity. Substrate preference for alkyl C and more degradation of lignified compounds were found in such substrates. Although no statistical differences in mass loss were observed for the rest of the fungi assayed, we detected changes in several of the parameters evaluated. This suggests that exotic invasions may alter ecosystem functioning by accelerating decomposition processes through an increased fungal ligninolytic activity.

The present investigation was attempted to assess the leaf litter production, decomposition rate and amount of major nutrient return in Populus deltoides, Eucalyptus tereticornis, Tectona grandis and Pyrus pyrifolia based agroforestry land use systems in Taran Taran district which falls in the north western agro-climatic zone of thePunjab state, India. The litter production in selected tree species was quantified using litter traps and decomposition pattern of leaf litter was investigated by litter bag technique. Litterfall in the selected tree species varied significantly (5 % level of significance) during different months of the study period. Among the four species, P. deltoides exhibited highest leaf litter production (7.8 tons/ha) followed by T. grandis (1.83 tons/ha) and E. tereticornis (1.77 tons/ha) whereas, lowest leaf litter production was observed in P. pyrifolia (0.34 tons/ha). The present study also showed that temperature as compared to rainfall play a significant (5 % level of significance) role in litter decomposition. In case of P. pyrifolia, P. deltoides and T. grandis decomposition take place 100 per cent, 98 per cent and 99 per cent respectively after 10 months whereas in E. tereticornis 87.7 per cent leaf decomposed after 10 months. The nutrients percentage through litter fall was maximum of nitrogen (2.27 %) followed by potassium (1.90 %) and phosphorous (0.32 %). Maximum and minimum N input through leaf litter was in P. deltoides (2.27 %) and P. pyrifolia (1.15 %). The K input (%) was maximum in leaves of T. grandis (0.32) and minimum in E. tereticornis (0.21). The maximum input of P (%) through leaf litter was in P. deltoides (1.90) whereas, minimum value was observed in E. tereticornis (1.27). Tree based agroforestry land use systems improve soil nutrient status as compared to traditional wheat and paddy based land use systems under this region of Punjab. Therefore tree based land use systems need to be promoted over the traditional field crops for realizing better environmental benefits in this region.

Mangrove restoration projects are now widely established, aiming to regain the carbon benefit of the mangrove ecosystem that is essential for climate change mitigation. This study aimed to investigate mangrove litter as the source of carbon in restored mangrove forests in Perancak Estuary, Bali, Indonesia, which previously experienced substantial mangrove loss due to shrimp aquaculture development. We assessed the production and decomposition of mangrove litter and associated macrozoobenthic biodiversity in restored forests with plantation age ≥14 years and intact mangrove forests as the reference. The monthly production of three groups of mangrove litter (leaf, reproductive, and wood) was assessed over 12 months. A leaf litter decomposition experiment was performed to inspect the interspecific and disturbance history variation in organic matter formation among four major mangrove species: Rhizophora apiculata, Bruguiera gymnorhiza, Avicennia marina, and Sonneratia alba. Our results showed that annual litterfall production from restored and intact mangroves in Perancak Estuary were 13.96 and 10.18 Mg ha−1 year−1, which is equivalent to approximately 6282 and 4581 kg C ha−1 year−1 of annual litterfall carbon sink, respectively. Although restored mangroves had significantly higher plant litterfall production than intact mangroves, no significant difference was detected in leaf litter decomposition and macrozoobenthic biodiversity between these forest types.

Slash-and-burn agriculture has been practiced for a very long time by the traditional populations (caiçaras) on Ilha Grande, Rio de Janeiro State, Brazil. After a few years of use the plots are abandoned to fallow. We examined the processes of litter production and decomposition and the relationships between forest lands used by caiçara populations and landscape functionality. Five and 25-year-old forests growing on areas once used for subsistence agriculture were compared to a near-climax forest site. No significant differences between the three areas were noted in terms of litter production over a 2-yr period; the average litter productions were 9,927, 8,707 and 10,031 kg/ha/yr for the 5-year, 25-year and climax forests respectively. N and K nutrient input through litter was greatest in the climax forest; P and Mg input was greatest in the 5-yr forest; and Na greatest in the 25-yr forest. Ground litter accumulation (3,040-3,730 kg/ha/yr) was not significantly different in the three areas. Litter turnover times (1/K) were 0.33, 0.42 and 0.38 for the 5-yr, 25-yr and climax forests respectively. These secondary forests cover almost all of Ilha Grande and demonstrate low species diversity, but they have production and decomposition systems similar to those of mature forests.

The litter is an important way of returning the organic matter to the soil, through the cycling of the nutrients, aiding in the development of the vegetation present in the ecosystems. The study aimed to estimate the spatio-temporal variation of deposition, accumulation and decomposition of the litter present in the preserved caatinga vegetation, located in the RPPN Fazenda Tamanduá in Santa Terezinha-PB, Brazil and the interference of climatic variables in the dynamics of these events. The research was conducted at RPPN Fazenda Tamanduá, in Santa Terezinha-PB, Brazil. The deposition of litter on 20 collectors of 1.0 m × 1.0 m was collected monthly in two periods: period I (August/2015 to July/2016) and period II (August/2016 to July/2017), the collected material was separated into leaves, branches + barks, reproductive and miscellaneous fractions. To estimate the rate of decomposition the litter accumulated on the forest floor was quantified using a 0.5 m × 0.5 m metal frame. The deposition of the total litter in periods I and II was 2,356.83 kg ha-1 and 1,163.67 kg ha-1, respectively. The leaf fraction was the one that contributed the most during the two collection periods. The analysis of the data allowed to conclude that the total litter deposition in the two periods is in line with the average production for the Caatinga. The increase in precipitation provided higher deposition of litter after the rainy season. Due to several factors, the decomposition of litter in the caatinga is slower than in other biomes.

Biogeochemical cycling study of ecosystems and their functioning are fundamental for planning conservation practices and management of forest remnants in Brazil. The objective of the study was to characterize the leaf litterfall production rate and the nutrients release via decomposition in a fragment of Seasonal Semideciduous Forest, in Southern Brazil, in advanced stage of regeneration. For two years, evaluations of litterfall and leaf litter decomposition (using the mass loss method with litterbags) were performed monthly, as well as their nutrient content analysis. Annual input of leaf litterfall was 4,532.7 kg ha-1 of dry matter, which promoted, for the two-year period, a supply of 195.5, 9.2 and 55.3 kg ha-1 of N, P and K, respectively. The litter nutrients use efficiency followed the decreasing order P > K > N. The annual decomposition constant for leaf litter was 1.16, reaching a half-life at 215 days, making 84.4% N, 72.7% P and 92.9% K available at the decomposition end of two years. In the two years of collection, the largest deposition rate of litter occurred in the spring, with the highest peak in October, indicating a seasonal deposition behavior. The forest fragment presents high production of leaf litter (66% leaves) and input of N. The rapid decomposition of leaf litter contributes to the release of nutrients over time, N and K initially, and P in the long run. P is limited due to the high efficiency of its use.

Abstract:Trends in structural and chemical leaf traits along a chronosequence of semi-evergreen tropical forest and their correlation with litter production and decomposition and associated carbon (C) and nitrogen (N) fluxes were assessed. Leaves of 15 dominant species in each plot were collected to measure leaf area, specific leaf area (SLA), C and N concentration and C:N ratio. Litterfall was measured and litter decomposition experiments were set up in 16 experimental plots in a chronosequence of secondary and mature forest. All five leaf traits combined discriminated the secondary forests from mature forest. SLA, N and C:N were significantly correlated to litter decomposition rates. Litter decomposition was significantly slower in mature forest compared with secondary forests. The N concentration of litter was lowest during the dry season, when litterfall was highest. N concentration in fresh leaves was higher than in litter, indicating that N is re-absorbed before leaf abscission. Leaf dynamics and associated nutrient cycling differ significantly between secondary forests and mature forest. Ecosystem-level leaf structural and chemical traits are good predictors of the stage of the forest and explain well the differences in decomposition rates between secondary and primary forests.

Litter production and its decomposition play an important role in the terrestrial carbon cycle and soil quality, being a crucial process involved in ecosystem productivity and functioning. Understanding this process under pine commercial stands or pine invasions is crucial to design forest management or ecosystems restoration. We conducted a study in a commercial pine plantation (Pinus taeda L.) under Atlantic Forest biome to investigate (1) the contribution of soil fauna to pine litter mass loss; (2) the litter fauna feeding activity within seasons. Litter bags with pine needles (5 g dry weight) were prepared as exclusion treatments for different sized soil fauna by varying mesh size (2 mm and 0.06 mm). Litter bags were removed after 60, 120, 180, 240, 300, and 365 days to estimate the decomposition rates. Bait lamina sticks were exposed seasonally and horizontally in soil surface to determine the fauna feeding activity on litter. We found: (1) no differences in litter mass loss and decomposition rate when soil macrofauna and most of the mesofauna were excluded; (2) feeding activity of litter organisms was higher in the summer, probably stimulated by a combination of high temperature and rainfall. In commercial pine stands, we can conclude that the nutrient cycling is slower than in natural areas, related to litter traits, as described in the scientific literature. Our results indicated that soil macro and mesofauna play a low role in the pine litter decomposition, where the organic material decomposition is more related to microorganism’s activity.

The temporal impact of clearing trees on litter production, litter decomposition and on C, N and P release through decomposition of litter was examined in the pasture systems of a semi-arid zone of central Queensland. Paired sites for cleared pastures (developed from clearing woodlands) and uncleared (intact woodland) pastures were selected to represent three dominant tree communities of the region i.e. Eucalyptus populnea, E. melanophloia and Acacia harpophylla, with three different time-since-clearing (5, 11–13 and 33 y) treatments. Yearly litter production was greater at uncleared sites (1732–1948 kg ha−1 y−1 for eucalypt and 2596 kg ha−1 y−1 for acacia communities) compared with cleared sites (1038–1282 kg ha−1 y−1 for eucalypt and 1100 kg ha−1 y−1 for acacia communities averaged over three time-since-clearing treatments). Rates of litter decomposition and of release of C, N and P from decomposing litter were higher at cleared than uncleared sites for all three tree communities. The cleared and uncleared sites did not differ significantly in total amount of C and N released per year since the concentrations of C and N were greater in litter from uncleared sites but the rate of release was less than that at cleared sites. Slow but continuous release of nutrients in eucalypt and acacia woodlands may be an adaptation of these communities to maintain the nutrient cycle and to avoid leaching of nutrients in the nutrient-poor soils of the region.

Litter fall consists of all organic material deposited on the forest floor, being of extremely important for the structure and maintenance of the ecosystem through nutrient cycling. This study aimed to evaluate the production and decomposition of litter fall in a secondary Atlantic forest fragment of secondary Atlantic Forest, at the Guarapiranga Ecological Park, in São Paulo, SP. The litter samples were taken monthly from May 2012 to May 2013. To assess the contribution of litter fall forty collectors were installed randomly within an area of 0.5 ha. The collected material was sent to the laboratory to be dried at 65 °C for 72 hours, being subsequently separated into fractions of leaves, twigs, reproductive parts and miscellaneous, and weighed to obtain the dry biomass. Litterbags were placed and tied close to the collectors to estimate the decomposition rate in order to evaluate the loss of dry biomass at 30, 60, 90, 120 and 150 days. After collection, the material was sent to the laboratory to be dried and weighed again. Total litter fall throughout the year reached 5.7 Mg.ha-1.yr-1 and the major amount of the material was collected from September till March. Leaves had the major contribution for total litter fall (72%), followed by twigs (14%), reproductive parts (11%) and miscellaneous (3%). Reproductive parts had a peak during the wet season. Positive correlation was observed between total litter and precipitation, temperature and radiation (r = 0.66, p<0.05; r = 0.76, p<0.05; r = 0.58, p<0.05, respectively). The multiple regression showed that precipitation and radiation contributed significantly to litter fall production. Decomposition rate was in the interval expected for secondary tropical forest and was correlated to rainfall. It was concluded that this fragment of secondary forest showed a seasonality effect driven mainly by precipitation and radiation, both important components of foliage renewal for the plant community and that decomposition was in an intermediate rate.

AIMS: This study aimed to evaluate, through an experiment with short sampling intervals, (1) the effects of detritus quality on dissolved oxygen (DO) consumption, on dissolved inorganic carbon (DIC) formation and on the stoichiometric ratio between the DO consumed and mineralized carbon (O/C ratio) during leaching of plant detritus in the early decomposition; (2) the temporal variation of the variables mentioned above according to changes in the quality of each detritus over time. METHODS: The detritus of leaves, branches and litter (3 g) previously dried were incubated in decomposition chambers containing 1 L of inoculum. The chambers were maintained at 24 ± 2 °C in aerobic condition. The DO concentrations dissolved organic carbon (DOC) and DIC were evaluated. The consumption of DO was adjusted to a first-order kinetic model. The hourly rates of DO consumption, DIC production and O/C ratios were determined. RESULTS: The DO consumption (2.62 mg.g-1) and DIC production (1.20 mg.g-1) were higher in leaves decomposition, and smaller in litter (1.50 and 0.42 mg.g-1, respectively). Inversely, the O/C ratio was higher in the decomposition of litter (3.56). The rates of DO consumption (0.50 mg.g-1.h-1) and DIC production (0.41 mg.g-1.h-1) were greatest in the early decomposition of leaves. CONCLUSIONS: Short sampling intervals are key to understanding the dynamics of decomposition in the leaching phase. Higher consumption of DO in leaves decomposition indicated a higher content of labile compounds in this detritus. The highest O/C ratios in the litter decomposition can be attributed to its higher content of refractory substances. Variations in DO consumption rates and in O/C ratios over time suggest that the leachate is heterogeneous, comprising labile and refractory fractions, analogous to the detritus as a whole. In terms of water quality alterations, leaves constituted the most critical resource and the litter presented less pronounced effects.

Field monitoring and incubation experiments were conducted to evaluate the litter yield and examine the decomposition of the litter of three representative mangrove species frequently used for mangrove re-vegetation in a subtropical mudflat on the South China coast. The results show that the litter yield of the investigated mangrove species varied significantly from season to season. The annual litter production was in the following decreasing order: Heritiera littoralis > Thespesia populnea > Kandelia obovata. Initially, rapid decomposition of easily degradable components of the litter materials resulted in a marked weight loss of the mangrove litter. There was a good linear relationship between the length of field incubation time and the litter decomposition rate for both the branch and the leaf portion of the three investigated mangrove species. Approximately 50% or more of the added mangrove litter could be decomposed within one year and the decomposed litter could be incorporated into the underlying soils and consequently affect the soil carbon dynamics. An annual soil carbon increase from 2.37 to 4.64 g/kg in the top 5 cm of the soil was recorded for the investigated mangrove species.

Full textAbstract:
The analysis of litter quantity, litter decomposition and its pattern of nutrient release is important for understanding nutrient cycling in forest ecosystems. Plant growth and maintenance are partly met through nutrient cycling (O'Connell & Sankaran 1997) which is dominated by litter production and decomposition. Litter fall is a major process for transferring nutrients from above-ground vegetation to soils (Vitousek & Sanford 1986), while decomposition of litter releases nutrients (Maclean & Wein 1978). The rate at which nutrients are recycled influences the net primary productivity of a forest. Knowledge of these processes from tropical rain forests is relatively poor (O'Connell & Sankaran 1997), and in particular there are no known published studies on nutrient cycling from lowland tropical forests in Papua New Guinea. The few studies from Papua New Guinea are confined to the mid-montane forest zone (Edwards 1977, Edwards & Grubb 1982, Enright 1979, Lawong et al. 1993).

Full textAbstract:
The growing demand for products of forest origin in the middle north region of Mato Grosso, Brazil has been increasing the production of the genus eucalyptus. This study aimed to assess the deposition and decomposition rates of litter at the central plot areas of Eucalyptus urograndis (Clone H13) areas of three, five, seven and nine years of age. In five and seven-year areas, the interfaces (borders) eucalyptus–crop and eucalyptus–native forest, and further, native forest remnant areas were assessed. Litter collectors with 1 m² area were installed and the deposited material was collected monthly. For quantifying the decomposition rates, collections were carried out at 30, 60, 120, 180, 240, and 300 days after installing the decomposition bags. In the dry season, higher amounts of deposited litter were observed, with a greater representation of the leaf fraction. Bark fraction presents positive and negative correlations with wind speed and relative air humidity, respectively. The litter balance found indicates that even under a tropical climate, high deposition rates occur when compared to the litter decomposition of E. urograndis, allowing significant increases of litter in planted areas as the age increased.

Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.

Full textAbstract:
Studies providing direct experimental evidence of species impact on litter dynamics in forest ecosystems are limited. The decomposition processes in subtropical forests are also poorly understood. We studied variation in quality and quantity of leaf litter production, decomposition, and N and P loss from decomposing foliar litter in three tree species as well as a mixed-species plot in a subtropical broad-leaved forest of northeastern India. The annual leaf litter production was highest in Rhododendron arboreum Sm. (7293 kg·ha–1·year–1) followed by Myrica esculenta Buch.-Ham. ex D. Don (6902 kg·ha–1·year–1), mixed plots (6808 kg·ha–1·year–1), and Neolitsea cassia (L.) Kosterm (6299 kg·ha–1·year–1). The annual N and P inputs through litter were highest in the mixed plot (N, 111.0 kg·ha–1·year–1; P, 4.8 kg·ha–1·year–1) and lowest in the Rhododendron plot (N, 65.6 kg·ha–1·year–1; P, 2.9 kg·ha–1·year–1). The highest decay rate was recorded for Neolitsea (k = 0.89) and lowest for Myrica (k = 0.53) litter. The rate of N loss was highest for Neolitsea (kN = 1.39) and lowest for Myrica (kN = 0.68) species, and P loss was in the order of mixed (kP = 1.02) > Neolitsea (kP = 0.88) > Rhododendron(kP = 0.84) > Myrica (kP = 0.62). Acid-insoluble residue, which indicates lignin content and P-related litter chemistry, were correlated with the differential decomposition rates and nutrient loss pattern among the species.

Litterfall is the essential source of organic matter and soil nutrients. The quality and quantity of litter production affect the carbon and nutrient fluxes in forest ecosystems. This study aims to determine the litter decomposition rate and macronutrients (N. P, K, Ca and Mg) in Taxus contorta Griff forests. The results showed that the maximum weight loss due to decomposition was recorded from June to October, and decay constant (K) was 0.534 during two years of study. Decomposition was significantly affected by climatic variables and positively correlated with temperature, rainfall, number of rainy days and relative humidity. The decomposing needles showed a continuous increase in nitrogen (0.97-1.27%) and phosphorus (0.11-0.13%) concentration and a gradual decrease in potassium (0.35-0.31%), calcium (0.93-0.45%) and magnesium (0.21-0.16%). Total nutrient return (37.33 kg ha-1) from the decomposing litter were observed in the order of Ca (15.09) > N (12.13) > K (5.73) > Mg (2.87) > P (1.50) through the input from different litter components, which were found in the order of needles > twigs > bark > miscellaneous litter > reproductive litter. Maximum nutrient return (15.82 kg ha-1) was observed through needle litter and was recorded as N (6.49), P (0.85), K (2.84), Ca (4.39) and Mg (1.24). Out of the total nutrients returned through needle litter, an annual release of 67% and accumulation of 33% nutrients over the forest floor of Taxus contorta was recorded.

Full textAbstract:
Abstract Soil enzyme activities are “sensors” of soil organic matter (SOM) decomposition since they integrate information about microbial status and physico-chemical condition of soils. We measured dehydrogenase enzyme activity in a deciduous temperate oak forest in Hungary under litter manipulation treatments. The Síkfőkút Detritus Input and Removal Treatments (DIRT) Project includes treatments with doubling of leaf litter and woody debris inputs as well as removal of leaf litter and trenching to prevent root inputs. We hypothesized that increased detrital inputs increase labile carbon substrates to soils and would increase enzyme activities particularly that of dehydrogenase, which has been used as an indicator of soil microbial activity. We also hypothesized that enzyme activities would decrease with detritus removal plots and decrease labile carbon inputs to soil. After ten years of treatments, litter removal had a stronger effect on soil dehydrogenase activity than did litter additions. These results showed that in this forest ecosystem the changed litter production affected soil microbial activity: reduced litter production decreased the soil dehydrogenase activity; increased litter production had no significant effect on the enzyme activity.

The litterfall and decomposition represent the main transfer of organic matter and nutrients from the vegetation to the soil surface and determine positive trajectories in the process of rehabilitating and restoring degraded ecosystems. The aim of this study was to evaluate the contributions of organic materials and nutrients through the characterization of fine litter in an urban dry forest fragment. Litter production was monitored for one year by collecting 29 traps (0.5 m2). To evaluate leaf nutrient resorption, green leaves were collected from 5-10 individuals that represented the dominant tree species. Litter-bags (20 x 20 cm, 2 mm pore) were used for six months to evaluate the decomposition of leaf litter. Annual fine litter production was found to be 8 574 kg ha-1, with the Cordia alba species contributing the most leaf litter (1 134 kg ha-1) and nutrients (N: 6.16; P: 0.21; Ca: 4.72; Mg: 0.47; K: 1.27 kg ha-1). Decomposition rates (k constant) followed the decreasing order: C. alba (k: 4.6) > Machaerium milleflorum (k: 3.5). M. milleflorum and Albizia niopoides presented a pattern of rapid N and P release in the first 30 days, with more than 80 % and 60 % released from M. milleflorum and C. alba, respectively, by the end of the experiment. The litterfall monitoring carried out in this urban dry forest fragment revealed some important aspects of the functioning of an ecosystem as seriously threatened as the tropical dry forest. Rev. Biol. Trop. 66(2): 571-585. Epub 2018 June 01.

Full textAbstract:
In the present study we investigated the production and decomposition of leaves, branches and roots in two moist regenerating tropical forests (5 and 15 years old; RF-5 and RF-15 respectively) and a natural forest (NF) in north-east India. Total litter input increased during vegetation succession (759, 1089 and 1284 g m–2 year–1 in RF-5, RF-15 and NF respectively), whereas the contribution of soft litter decreased sharply. Decomposition over 450 days indicated significant seasonal (P < 0.001) patterns in mass loss of litter components, with greater rates during the wet period. Soil CO2 efflux was strongly seasonal. C stock loss followed patterns similar to those of mass loss, whereas N increased initially, followed by its gradual release. Rainfall explained 74–90% of the variability in mass loss rates. Concentrations of cellulose and N were significantly positively correlated with mass loss at an early stage of decomposition (r = 0.54–0.65, P < 0.05), whereas lignin : N and C : N ratios were negatively correlated with mass loss at later stages. Regenerating forests adapted ecosystem-level strategies that induced early leaf fall to reduce soil water loss, increase organic matter return to the soil and conserve N through immobilisation during the process of decomposition to speed up vegetation succession in the regenerating forest.

Full textAbstract:
Termites are abundant arthropods in tropical ecosystems and actively participate in the process of litter decomposition. The objective of this study was to evaluate the population structure of Microcerotermes indistinctus in arboreal nests and to estimate their contribution to the consumption of wood litter in an area of Caatinga, a type of seasonally dry tropical forest located in the Brazilian semi-arid region. The populations of fifteen nests were quantified and separated into castes, “larvae”, and eggs. Wood blocks of four typical Caatinga species were offered to termites under laboratory conditions. Litter production was estimated in the area over the course of one year. The mean population size of M. indistinctus was 73,897 individuals/nest, while the mean nest density in the area was 25 active nests/ha. Total consumption of the four types of wood was estimated to be 10.5 mg of wood/g termite (fresh weight)/day. Based on consumption and population size, M. indistinctus consumes 0.35% of the total litter and 1.71% of the annual production of branches and twigs in the area. Wood-consuming termites are highly affected by anthropogenic disturbances in the semi-arid region of Brazil, putting the ecosystem services they perform related to the process of litter decomposition at risk.
