Abstract (sommario):
Summary. The growth of sugarcane in soils from land monocultured with sugarcane, and from land which had either never been cropped with sugarcane, or just recently cropped, was compared under glasshouse conditions. In general, cane growth in new land soils was greater than in monocultured soil (shoot growth 7.4%, root growth 21.4%). Responses to soil pasteurisation were investigated in some soils and were greater in monocultured soils suggesting that root growth constraints were larger in the monocultured soil (210% response in monocultured soils v. 64% in new land soils). Assays for sugarcane root pathogens suggested that Pachymetra chaunorhiza was a major contributor to the old/new land growth responses, but it is unlikely that Pythium spp. were factors in the growth differences. Monitoring of other groups of organisms in soil from one site suggested that sugarcane monoculture may affect populations in the broader biological community.

Abstract (sommario):
Background Exploring high-quality organic amendments has been a focus of sustainable agriculture. Filtered mud (FM), a sugar factory waste derived from sugarcane stems, could be an alternative organic amendment for sugarcane production. However, the effects of its application proportions on soil fertility, nutrient cycling, structure of soil bacterial and fungal communities, and the growth of sugarcane in clay-loam soils remain unexplored. Methods Three application proportions of FM: (FM1-(FM: Soil at 1:4), FM2-(FM: Soil at 2:3), and FM3-(FM: Soil at 3:2)) were evaluated on sugarcane growth and soil nutrient cycling. High throughput sequencing was also employed to explore soil microbial dynamics. Results We observed that FM generally increased the soil’s nutritional properties while improving NO3− retention compared to the control, resulting in increased growth parameters of sugarcane. Specifically, FM1 increased the concentration of NH4+−N, the N fraction preferably taken up by sugarcane, which was associated with an increase in the plant height, and more improved growth properties, among other treatments. An increase in the proportion of FM also increased the activity of soil nutrient cycling enzymes; urease, phosphatase, and β-glucosidase. High throughput sequencing revealed that FM reduced the diversity of soil bacteria while having insignificant effects on fungal diversity. Although increasing FM rates reduced the relative abundance of the phyla Proteobacteria, its class members, the Gammaproteobacteria and Betaproteobacteria containing some N-cycling related genera, were stimulated. Also, FM stimulated the abundance of beneficial and lignocellulose degrading organisms. These included the bacterial phyla Actinobacteria, Bacteroidetes, Acidobacteria, Chloroflexi, and the fungal phylum Ascomycota. The distribution of the soil microbial community under FM rates was regulated by the changes in soil pH and the availability of soil nutrients. Since FM1 showed more promise in improving the growth properties of sugarcane, it could be more economical and sustainable for sugarcane production in clay-loam soils.

Abstract (sommario):
Bagasse is an agricultural by-product derived from the sugarcane milling process. It is a dry and fibrous residue left after the extraction of sugar juice from sugarcane. Over 2 million metric tons of bagasse is generated each year in South Florida, and need exists to find environmentally sustainable, yet economically viable use for it. Application of bagasse as a potential soil amendment on mineral soils to grow sugarcane seems like a good option to utilize the product. This factsheet explores the feasibilty of using bagasse as a organic soil amendment to grow sugarcane on mineral soils in South Florida.

Abstract (sommario):
AbstractSugarcane is an energy crop with great economic potentials. Information on soil evaluation for sugarcane in central Nigeria is very scanty. This study was carried out to evaluate the suitability of some soils of the floodplains in central Nigeria for sugarcane cultivation. A semi-detailed soil survey was carried out on 18,500 hectares of land straddling the floodplains of Rivers Niger and Benue in Korton-Karfe Local Government Area of Kogi State. Land resource survey was carried out using a 500 m×500 m grid pattern. Identified soil types were further examined with standard soil profiles. Samples were collected from the soil genetic horizons as well as surface (0–30 cm) soils at selected sampling points for fertility analysis. Parametric and non-parametric suitability evaluation methods were used to relate land qualities with land use requirements for commercial sugarcane cultivation. Relationships between evaluation methods were assessed using Spearman’s rank correlation coefficients. Nine soil mapping units were identified in the study areas which were mainly Inceptisols (55.4%) and Alfisols (22.5%) which correlates with Fluvisols (40.4%), Cambisols (15.1%) and Lixisols (22.5%) in the World Reference Base (WRB) classification system. The evaluation methods used revealed that 0%, 4.95%, 49.48%, 23.55% of the soils were highly suitable (S1), moderately suitable (S2), marginally suitable (S3) and not suitable (N) for sugarcane cultivation, respectively. Potentially, 0%, 9.52%, 44.91% and 23.55% of the soils were found to be highly suitable (S1), moderately suitable (S2), marginally suitable (S3) and not suitable (N) for sugarcane cultivation, respectively. The soils were strongly limited by low soil nutrient availability, soil acidity and flood hazard. Soil management practices such as application of organic manures, fertiliser and liming could be adopted to ameliorate the soil acidity and supply deficient nutrients while land development strategies such as drainage, flood control and possibly sub-soiling would mitigate other major limitations to sugarcane cultivation.

Abstract (sommario):
Abstract Wireworms (Coleoptera: Elateridae) are major economic pests of Florida sugarcane (Saccharum spp. hybrid). The corn wireworm, Melanotus communis (Gyllenhal), is the most important wireworm pest of Florida sugarcane occurring in both sandy and muck soils. The objective of this study was to determine survivability, preference, and dispersal of wireworms in sandy and muck soils. There was no significant difference in starved wireworm survival between the soils after 2 mo. However, the starved wireworms gained more weight in muck soil than in sand. Wireworms dispersed at similar rates toward oat baits in both soil types. Interestingly, in free choice tests wireworms showed a high preference to reside in muck versus sandy soil, which corresponds to the greater wireworm weight change found in muck versus sandy soil. The high preference for muck and greater weight gain in muck found in this study partially explains why M. communis is more abundant in muck soils than in sandy soils in Florida sugarcane.

Testo completo
Abstract (sommario):
Soil microbial activity can be constrained by availability of energy because soil carbon (C) occurs mostly as complex soil organic matter (SOM), with relatively small quantities of high-energy, labile C. Decomposition of SOM is mediated by energy-requiring processes that need extracellular enzymes produced by soil microbial communities. We examined how an increase in energy status via sucrose supplementation affects the production of SOM-degrading enzymes, comparing matched soils under forest and sugarcane agriculture with histories of contrasting inputs of complex and labile C. Activities of SOM-degrading enzymes increased in both soils after sucrose addition, but CO2 production increased more rapidly in the sugarcane soil. The forest soil had greater increases in phosphatase and glucosidase activities, whereas the sugarcane soil had greater increases in protease and urease activity. The contrasting microbial community-level physiological profiles of the soils further diverged at 30 and 61 days after sucrose amendment, before returning to near pre-treatment profiles by 150 days. We interpreted the increasing soil enzyme production as indicative that enzyme production was limited by energy availability in both soils, despite contrasting histories of labile v. recalcitrant C supply. Quicker responses in sugarcane soil suggest pre-selection towards populations that exploit labile inputs.

Testo completo
Abstract (sommario):
Current strategies for phosphorus (P) fertiliser management in the Australian sugar industry do not account for the differences between different soils in their ability to sorb and release P. However, the off-site export of P from land under sugarcane has been shown to be a major factor contributing to elevated concentrations of P in stream waters draining catchments dominated by sugarcane production. This paper presents the results of a study conducted in the lower part of the catchment of the Herbert River, north Queensland, a major sugarcane growing region. Our approach was to combine a knowledge of P sorption by soil and riverine sediments with an assessment of the risk of P loss from lower Herbert sugarcane soils and knowledge of the requirements of sugarcane for P. The results provide a basis for future P fertiliser management by canegrowers which accounts for both production and environmental imperatives. They also point to an urgent need for experimentation, based on rundown of soil P fertility, to determine critical soil test values in soils of varying P sorption, and provide a useful regional framework for the design of such experimentation.

Abstract (sommario):
This paper studied the vertical distribution of heavy metals in sugarcane soils by using sugarcane vinasse. The results showed that the sugarcane vinasse not only reduced the pH value of the sugarcane fields, but also increased the concentration of organic matter. The Cu content decreased with soil depth, and six sampling points appeared peaks in the range of 30~40cm.There was not obvious change of Cd content in soil depth of 0~60cm. And the content of Zn and Pb showed different changes with different sampling points. The study also showed that the mobility of four heavy metals followed the order Cu> Zn> Pb> Cd. Besides, the content of Cu and Cd in some layers were exceeded soil background value of Guangxi. The geo-accumulation index indicated that the 36 samples collected from different layers were not contaminated by Cu, Zn, Pb and Cd, and the sugarcane soils were in clean state.

Abstract (sommario):
Sugarcane intercropping with soybean [Glycine max (Linn.) Merr.], mung bean [Vigna radiata (Linn.) Wilczek] and peanut (Arachis hypogaea Linn.) as well as a sugarcane monoculture were conducted to study the impacts of intercropping on soil biological characteristics and bacterial diversity. The results showed that soil cultivable microorganisms, the activities of soil enzymes and microbial biomass carbon, nitrogen, and phosphorus were all significantly improved by intercropping with soybean and mung bean. Additionally, soil bacterial diversity and richness in sugarcane fields were also significantly enhanced by intercropping with soybean and mung bean. In addition, soil bacterial community structures in sugarcane fields can be altered by intercropping with different legumes. Proteobacteria, a high-nutrient-tolerant bacterial assemblage, became the dominant bacteria in the sugarcane-soybean and sugarcane-mung bean intercropped soils. Twenty four, 28, 26 and 27 dominant soil bacterial genera were found after the sugarcane-soybean, sugarcane-mung bean, sugarcane-peanut and sugarcane monoculture treatments, respectively. Sugarcane-mung bean intercropping being the most promising system for regaining and improving soil fertility and soil heath and facilitate agriculture intensification of sugarcane.

Abstract (sommario):
Nowadays, due to the expansion of agricultural borders, it is highly desirable to increase the sustained productivity of sugarcane cultivars using the knowledge of soil microbial communities. In this study, twelve shotgun metagenomic datasets based on genomic DNA from soil were analyzed using the Metagenomics Rapid Annotation using Subsystem Technology (MG-RAST) and Statistical Analysis of Metagenomic Profiles (STAMP) to assess differential responses for the total soil bacterial community composition and nitrogen-cycling microbial community functional potential in soils from sugarcane field with pre-harvest burning and adjacent forest in dry and wet seasons in Southeast Brazil. The soil bacterial community revealed higher abundance for Actinobacteria in forest soil than sugarcane soil in dry and wet seasons, and an opposite pattern for Proteobacteria and Planctomycetes in these soils in both seasons. The results obtained in this study based on the KEEG map suggest that the forest soil has a higher nitrogen-cycling microbial community functional potential compared to the sugarcane soil, independently of the season. The gene sequences associated with carbohydrate metabolism were the most frequent in all soil metagenomes. Taken together, the results confirm previous findings regarding the effects of forest conversion to sugarcane production area, providing new insights regarding to this conversion through the prism of the seasonality and pre-harvesting method on microbially mediated nitrogen cycle in sugarcane production fields.

Abstract (sommario):
Sugarcane is considered as the most abundant plant based crop grown in the tropics and part of the temperate climates. Its by-product, sugarcane bagasse, constitutes 30% of the total production. In the past, it was considered as waste material but contemporaries through innovative research projects over the years have found uses for it. Among these projects is soil reinforcement, which provides an alternative application to industrial by-products and natural fibres as a way of reducing their environmental footprints and contributing to sustainable geotechnics. Although bagasse morphological composition contains structural elements ideal for reinforcement and composite materials, it has received little research as a standalone reinforcement material. Because of this, a direct shear test was therefore initiated to establish the usefulness of using sugarcane bagasse as a soil reinforcement material by comparing the extent of shear strength and stiffness response due to its inclusion to unreinforced soil. Three different types of bagasse, fibre, millrun and pith, were added to unreinforced soil in percentage by weight content of 0.3 - 1.7. The bagasse was added to Klipheuwel sand, Cape Flats sand and Kaolin Clay at both dry and moist conditions. In addition, durability studies involving 12 cycles of wetting and drying, and soaking for a period of 14 days were constituted.

Abstract (sommario):
Nitrogen (N) plays a vital role in plant metabolic processes, and may cause severe economic losses in crop production if deficient. When agricultural composts are used to counteract soil impoverishment and supply crop nutrients, it is crucial to understand the dynamics of nitrogenous compounds to optimize N uptake. Five major soil groups of Mauritius were amended with three types of compost, filtercake (FC), poultry litter (PL), and poultry manure-sugarcane thrash (PM), at application rates to supply 140 kg N ha-1in a laboratory incubation experiment over 215 days. In each soil group, only specific types of agricultural composts resulted in a statistically significant (P < 0.05) increase in cumulative N mineralized, relative to the control: PM in the Low Humic Latosol (L), PM and PL in the Humic Latosol (H), PL in the Humic Ferruginous Latosol (F), PL in the Latosolic Reddish Prairie (P) group, and FC and PL in the Latosolic Brown Forest (B) group. In general, the N-NO3- form was dominant in all the treatments across the soil groups. Only in the H soil amended with PM and PL was the N-NH4+ form pre-dominant. The index of N availability, N0k, showed that in control soils, the daily N availability (mg N kg-1 soil day-1) was in the order B (1.242) > H (0.975) > F (0.674) > P (0.637) > L (0.524). The relatively high N availability in the B may explain why sugarcane cultivated in this soil islowly responsive to increments in N fertilizers. Relative to the control soils, FC resulted in a decrease in N availability, mostly due to a relatively slower rate of N mineralization. Poultry litter compost increased daily N availability in all the soil groups. Increased N availability was also noted in all soils amended with PM, except in the P soil. In general, the percentage of organic N mineralization in control soils varied from 2% to 4%. In FC-amended soils, between 2% and 5% of the organic N from soil and compost mineralized. Applied in the weathered soil groups (H, L and F), PM resulted in an appreciable increase in organic N mineralized that varied between 6% and 9%. However, in the immature soil, PM had a relatively mitigated effect, with 1% of total N mineralization in the amended P soil, and 3% in the B soil. Across the soil groups amended with PL, from 4% to 8% of the total soil and compost organic N mineralized.

Abstract (sommario):
The environmental conditions driving the microbial community dynamics in crop soils remain unclear. Here, we focused on the spatial and temporal dynamics of microbial communities in soils cultivated with sugarcane under different soil managements, during two years. Our work was divided into three essential parts, where i) we discuss ecological models and theories for the microbial exploration in crop soils, arguing that those ecological models, which partitioned the microbial communities, may increase the resolution of the environmental and the microbial interactions; ii) we developed a probabilistic model based on the occurrence frequency of microorganisms across systems identifying the core microbial community. The model is based on the Poisson distribution, and it was tested in four datasets available in the Earth Microbiome Project; iii) we identified the core bacterial and fungal communities across soils cultivated with sugarcane, verifying which abiotic components could drive the composition of groups. We increased the resolution of the environmental and the microbial interactions, showing that the core and the variable microbial communities are driven by distinct abiotic components. We also observed that the core and variable microbial communities harbor distinct potential functionality, as nitrogen fixation being more predicted to the core bacterial commmunity, and nitrification process for the variable bacterial community. Our finds increase the knowledge of microbial dynamics and functionality, helping to reveal and explore the crop system microbiome.
As condições ambientais que podem modular a dinâmica da comunidade microbiana em solos de culturas são pouco conhecidas. O presente trabalho foi dividido em três partes essenciais, onde i) discutiu-se modelos e teorias ecológicas para a exploração microbiana em solo agrícolas, argumentando-se que os modelos ecológicos que particionam as comunidades microbianas, poderiam aumentar a resolução entre interações microbianas e o ambiente, ii) desenvolveu-se um modelo probabilístico baseado na freqüência de ocorrência de microorganismos através de sistema identificando a comunidade microbiana \"core\". O modelo baseou-se na distribuição de Poisson, sendo este testado em quatro conjuntos de dados disponíveis no Projeto \"Earth Microbiome\", e iii) identificou-se as comunidades bacterianas e fúngicas core em solos cultivados com cana-de-açúcar, verificando-se quais componentes abióticos poderiam modular a composição dos grupos. Com isso, elevou-se a resolução das interações ambiental e microbiana, indicando que o core microbiano e as comunidades microbianas variáveis são moduladas por componentes abióticos distintos. Observou-se também que as comunidades core e variável possuem funcionalidade potencial distinta, como fixação de nitrogênio mais predita para o core bacteriano e processo de nitrificação para a comunidade variável de bactérias. Os resultados do presente trabalho elevam o conhecimento da dinâmica e funcionalidade microbiana, ajudando a revelar e explorar o microbioma do sistema de cultivo.

A imobilização dos contaminantes utilizando carvão vegetal funcionalizado (CVf) ou também chamado biocarvão (BC) em tratamento de água e solo recebe um papel cada vez mais importante e é considerado como uma boa alternativa de remediação. Além disso, atualmente tem se muito em conta a produção do CV, utilizando biomassa, ou subprodutos agrícolas. O biocarvão possui alta capacidade de troca de cátions, grande área de superfície, bem como um grande tamanho de micro poros. Estes fatores geram uma adsorção significativa de metais contaminantes. Deste modo, o CVf desempenha um papel importante no controle de contaminantes ambientais. O objetivo deste trabalho foi avaliar amostras de carvão vegetal funcionalizado (CVf) obtido a partir do bagaço da cana, a fim de determinar a retenção de alumínio para a sua possível aplicação em solos contaminados. O projeto foi dividido em etapas. Em primeiro lugar, foi desenvolvido um protocolo para a obtenção de carvão vegetal funcionalizada (CVF). Na segunda parte, foram realizados ensaios de retenção de alumínio em CVf, variando o pH, a quantidade de CVF e da concentração de metal. A partir de esta avaliação, determinou-se as condições ideais para a máxima remoção de metal em solução aquosa, sendo pH 5, tempo de 6 hr e concentração de CVf de 10 mg/l, para depois estudar sua possível aplicação no condicionamento do solo. Foram realizadas análises químicas e complementares das amostras do CVf, tais como MEV/EDS, Infravermelho (FTIR) e espectrofotometria de absorção atômica para caracterizar o produto. O comportamento do fenômeno de adsorção foi demonstrado testando os modelos de Langmuir e Freundlich. Os resultados da caracterização e processo adsortivo, foram similares aos relatados na literatura, e os dados de adsorção se acoplaram o modelo de Freunlinch. Como esperado, na interação do material obtido e o solo, a capacidade de adsorção do alumínio, e a CTC e pH, aumenta com o acréscimo da concentração de CVF assim como a quantidade de alumínio retido, concluindo que o CVF é uma boa opção como condicionador de solo, especialmente em solos ácidos para remoção de alumínio livre.
The Immobilization of contaminants using functionalized charcoal (CVf), or also called biochar (BC) in water and soil treatment gets an increasingly important role and it is considered as a good alternative of remediation. In addition, currently it has taken account the CVf production, using biomass, or agricultural by-products. The biochar has a High cation exchange capacity (CEC), large surface area as well as a big micropores size. These factor will generate a significant adsorption of contaminating metals. Thus, the CVf plays an important role in the control of contaminants. The objective of this work is to evaluate samples of functionalized Biochar (CVf) which was obtained from the sugarcane bagasse in order to determine the aluminum retention for its possible applicability in contaminated soil. The project was divided into stages. Firstly, it was developed a protocol in order to obtain functionalized charcoal (CVf). In the second part, aluminium adsorption test were carried out in CVf, varying the pH, amount of sorbent and metal concentration. Finally, it was determined the optimum conditions for the maximum metal removal on liquid media, being pH 5, time of 4 hr, and CVf concentration of 10 mg/l, following its possible application in the soil conditioning. It was necessary to carry out chemical and complementary analysis of the samples such as SEM-EDS, infrared (FTIR), and atomic absorption spectrophotometry to characterize the product. The behavior of the adsorption phenomenon was demonstrated by testing the Langmuir and Freundlich models. The results of the characterization and adsorption process were similar to those reported in the literature, and the adsorption data were coupled to the Freunlinch model. As expected, in the interaction of the material obtained and the soil, the CEC and pH, increases with the increase of CVf concentration as well as the amount of aluminum retained, concluding that functionalized charcoal (CVf) is a good option for soil conditioner, especially in acid soils for free aluminum removal.

Knowledge of the factors related to the dynamics of herbicides in the environment is of fundamental importance to predict the behavior of herbicides in different soil types and selection of appropriate doses and to avoid harmful effects to the environment and subsequent crops. Three experiments were conducted in order to analyze the dynamics of sulfentrazone in five soils of sugarcane areas of the Brazilian Northeast: Quartzipsamment (Peter Old-RN), Cambisol (Quixeré-CE); Oxisol (Coastal Plains - Maceió-AL), Red-Yellow Ultisol (Coastal Plains - Maceió-AL) and an Epiaquic Haplustult (floodplain - Maceió-AL). The first experiment aimed to characterize chemically, physically and mineralogically the topsoil of different soil classes. The characterization of soil attributes allowed to observe that areas with cane sugar cultivation vary depending mainly physical attributes, with soils of different textural classes and chemical attributes, highlighted with total Organic Carbon content and P available. Regarding the mineralogy, it was observed that the sugarcane areas are installed from young soils with predominance of 2: 1 clay soils to more developed with the presence of kaolinite, gibbsite and iron oxides. The second experiment aimed to evaluate the sorption and desorption of sulfentrazone in the five soils mentioned above was conducted in laboratory conditions. Freundlich equation was adjusted to obtain the sorption coefficients, Kf (sorption capacity) and 1 / n (intensity sorption). It was observed that the soils have different behavior in relation to sulfentrazone sorption potential. Based on the results of this second study, we concluded that the increasing order of sorption was: Argisol (Kf = 8.74)> Oxisol (Kf = 8.23)> Quartzipsamment (Kf = 7.50)> Inceptisol (Kf = 6 98)> Gleysol (Kf = 6.67); while desorption decreased in the following order: Argisol Oxisol (35 cm)> Argisol (20 cm) = Inceptisol (20 cm) = Gleysol (20 cm). Before making the recommendation of sulfentrazone, we must know the chemical, physical and mineralogical characteristics of soils and their interactions with the herbicide, in order to ensure technical efficiency and environmental sustainability

Foram conduzidos três experimentos, visando a analisar a dinâmica do herbicida sulfentrazone em cinco solos de regiões canavieiras do Nordeste brasileiro: Neossolo Quartzarênico (Pedro Velho-RN), Cambissolo Háplico (Quixeré-CE); Latossolo Vermelho-Amarelo (Tabuleiros Costeiros - Maceió-AL), Argissolo Vermelho-Amarelo (Tabuleiros Costeiros - Maceió-AL) e um Gleissolo Háplico (várzea - Maceió-AL). O primeiro experimento objetivou caracterizar química, física e mineralogicamente a camada arável de diferentes classes de solos. A caracterização dos atributos dos solos permitiu observar que as áreas com cultivo de cana-de-açúcar variam em função principalmente dos atributos físicos, com solos de diferentes classes texturais e atributos químicos, tendo destaque o teor de Carbono Orgânico total e P disponível. Em relação à mineralogia, foi possível observar que as áreas canavieiras são instaladas desde solos jovens com predomínio de argilominerais 2:1 até solos mais desenvolvidos com presença de caulinitas, gibsita e óxidos de ferro. O segundo experimento, com objetivo de avaliar a sorção e a dessorção do sulfentrazone nos cinco solos anteriormente mencionados foi conduzido em condições de laboratório. Foram ajustadas equações de Freundlich para obtenção dos coeficientes de sorção, Kf (capacidade de sorção) e 1/n (intensidade de sorção). Observou-se que os solos estudados apresentam comportamento diferenciado em relação ao potencial de sorção do sulfentrazone. Com base nos resultados deste segundo trabalho, conclui-se que a ordem crescente de sorção foi: Argissolo (Kf = 8,74) > Latossolo (Kf = 8,23) > Neossolo Quartzarênico (Kf = 7,50) > Cambissolo (Kf = 6,98) > Gleissolo (Kf = 6,67); ao passo que a dessorção decresceu na seguinte ordem: Argissolo < Gleissolo < Neossolo Quartzarênico < Cambissolo < Latossolo. O terceiro trabalho propôs avaliar a lixiviação do herbicida sulfentrazone nos referidos solos por meio de bioensaios e cromatografia líquida de alta resolução. Baseado nos resultados, conclui-se que a mobilidade do sulfentrazone nos solos é influenciada pelas suas características químicas, físicas e mineralógicas, apresentando a seguinte sequência de potencial de lixiviação: Neossolo Quartzarênico (45 cm) > Latossolo (35 cm) > Argissolo (20 cm) = Cambissolo (20 cm) = Gleissolo (20 cm). Antes de fazer recomendação do sulfentrazone, é necessário conhecer as características químicas, físicas e mineralógicas dos solos e suas interações com o herbicida, no intuito de garantir eficiência técnica e sustentabilidade ambiental

Abstract (sommario):
O Brasil se destaca como o maior produtor de cana-de-açúcar do planeta. Como resultado do aumento da demanda de açúcar e etanol, cerca de 4 milhões de hectares foram convertidos em áreas de cana-de-açúcar nos últimos 10 anos. Espera-se que outros 6 milhões de hectares sejam convertidos nos próximos 10 a 20 anos para suprir a demanda nacional de derivados dessa cultura. Estas modificações podem ocasionar a emissão de gases do efeito estufa, resultantes principalmente da decomposição da matéria orgânica do solo, o que pode levar a dívida de carbono. Por outro lado, a substituição de áreas degradadas pelo cultivo da cana-de-açúcar pode acarretar no incremento dos estoques de carbono dos solos promovendo o sequestro de carbono. O principal objetivo foi proceder a metodologia proposta pelo Painel Intergovernamental de Mudanças Climáticas (IPCC) da Organização das Nações Unidas para avaliar o impacto ocasionado pela expansão do cultivo da cana-de-açúcar sobre a matéria orgânica do solo e seu resultado em emissão de CO2 ou em sequestro de carbono. O total de 142 situações de campo foram avaliadas na região Centro Sul do Brasil, onde a cana-de-açúcar vem substituindo outros usos da terra gerando o total de 6318 amostras de solo que foram analisadas considerando as três principais conversões existentes para cana-de-açúcar no país: i) Cerrado; ii) Pastagens e iii) Áreas de cultivo anual. Os resultados obtidos indicam o decréscimo dos estoques de carbono dos solos quando o cultivo de cana-de-açúcar substitui o cerrado e áreas de pastagens, e promove o incremento quando áreas de culturas anuais são substituídas. Os fatores de mudança de uso da terra referente ao período de 20 anos após a conversão de cerrado para cana-de-açúcar referente às camadas 0-30 cm, 0-50 cm e 0-100 foram respectivamente 0,79 (±0,04), 0,86 (±0,04) e 0,94 (±0,04). Para a conversão de pastagens para o cultivo de cana-de-açúcar, os fatores de impacto de mudança de uso da terra foram 0,91 (±0,04), 0,94 (±0,04) e 0,98 (±0,04), e para a conversão de áreas de cultivo anual os fatores de impacto de mudança de uso da terra foram 1,20 (±0,18), 1,20 (±0,18) e 1,21 (±0,18). O período de compensação da dívida de carbono gerada foi estimado entre 3,5 a 6,3 anos considerando a substituição de cerrado, 1 a 2 anos para áreas convertidas de pastagens e zero para áreas oriundas de cultivo anual, onde não foi observada dívida de carbono. Espera-se que os resultados gerados por este trabalho de pesquisa possam subsidiar os tomadores de decisão como forma de desenvolver políticas apropriadas para a expansão do cultivo da cana de açúcar na região Centro Sul do Brasil promovendo desenvolvimento com baixo impacto ao meio ambiente
Brazil figures as the major sugarcane producer in the world and as result of increasingly demand for sugar and ethanol about 4 millions of hectares were converted into sugarcane systems on last 10 years and others 6 millions of hectares are expected to be converted in next 10 to 20 years. This modification can increase greenhouse gas emissions as result of soil organic matter decomposition and lead to a carbon debt. The aim of this research paper was to perform the IPCC\'s Tier 2 approach to evaluate the impact of sugarcane expansion over the soil organic matter, and their results in CO2 emissions or soil carbon sequestration. A total of 142 field situations were studied in South-Central Brazil where sugarcane substituted other land uses, providing 79 comparison pairs and 6,318 soil samples that were analyzed considering three major conversions to sugarcane: i) Cerrado (Brazilian savannah); ii) Pastures; iii) Annual Cropland (maize or soybean). Our results indicate the decrease of soil carbon stocks when sugarcane overcomes cerrado and pastures, and an increase when annual cropland is replaced. The land use change impact factors after 20 years of conversion from cerrado to sugarcane for 0-30 cm, 0-50 cm and 0-100 cm layers were respectively 0.79 (±0.04), 0.86 (±0.04) and 0.94 (±0.04). For sugarcane replacing pastures the impact factors were 0.91 (±0.04), 0.94 (±0.04) and 0.98 (±0.04), and for the conversion from annual agriculture impact factors were 1.20 (±0.18), 1.20 (±0.18) and 1.21 (±0.18). The repay time for the carbon debt was estimated in 3.5 to 6.3 years considering the substitution of cerrado, 1 to 2 years for areas coming from pastures and zero for areas coming from cropland, where no carbon debt was found. We expect that results of this research paper can subsidize appropriate policies for sugarcane expansion in South-Central Brazil, promoting development with a lower environmental impact

Abstract (sommario):
The interest in using sugarcane straw as a feedstock for bioenergy production has been increased considerably. However, indiscriminate straw removal may negatively affect soil functioning. Therefore, this work aimed to quantify and characterize soil solution translocating along the profile, under straw removal rates from the soil surface. Lysimeter systems were built with 1, 20, 50, and 100 cm soil columns, with a sandy clay loam texture, from a commercial sugarcane field in Piracicaba-SP, southeastern Brazil. The experiment was conducted in open area, where the lysimeters were subjected to rainfall and sun radiation. After the soil stabilization within the lysimeters, the treatments were added, consisting of four straw amounts (0, 3, 6, and 12 Mg ha-1), representing straw removal rates of 100 (bare soil), 75, 50, and 0%, respectively. After one year of the first straw addition, the same straw amounts were added again simulating the second harvest. Drained solution was collected and quantified by 17 months and soil moisture was determined over a period of two months using sensors. Dissolved organic carbon (DOC) concentration was measured in automatic analyzer. The soil solution and straw solution, made in water infusion, were characterized in High performance liquid chromatography (HPLC) to verify the presence of toxic compounds. After that, straw and soil solution were used in tests with soybean seed to evaluate the effects in plant germination and initial growth. At the end of the experiment, soil bulk density and soil organic carbon (SOC) analyses were performed. Remaining straw was weight before the new addition, and weight again at the end to determine the decomposition rates. The accumulated volume of solution drained was 30, 11 and 4% lower under 100, 75 and 50% removal rates compared to no removal. Bare soil stored less water, indicating susceptibility to lose water by evaporation. Simulation showed that 100% and 75% removal can induce longer periods of water restriction, which impair sugarcane growth. The DOC production on topsoil was higher in no straw removal; the retention was higher in 1 to 20 cm in no removal and higher in 20 to 50 cm in 50 and 75% removal rates. Bare soil released more DOC below 01 cm indicating a possible C loss. Below 100 cm DOC leachate was quite similar in all treatments, what shows a higher C retention and small C loss even in higher DOC production. Even with differences in DOC retention, increases in C stock below 5 cm were not noticed. We found many phenolic compounds in the straw solution, not found in the soil solution, indicating that in natural conditions straw does not release toxic compounds into soil solution. Plant growth was negatively affected by straw solution, but not by soil solution. Our findings suggest that the medium straw maintenance prevents variations and loss on soil water content. Higher straw amount increases DOC production, which likely alters its composition and subsequent retention in soil. Carbon stock did not increase in the soil subsurface, but probably will in the long-term. The higher straw removal, proportionally, the higher the C losses in the form of CO2 and DOC, consequently the lower soil C retention. More straw on soil surface release more C amounts to the soil, retained or translocated with soil water, may be stored in deeper soil layers. Higher water percolation in the soil profile does not mean higher C losses by leaching in deeper soil. This study has the practical objective of finding an amount of straw to be maintained in the field that ensures the C storage and the better soil functioning, and also supply feedstock for bioenergy production.
O interesse no uso da palha de cana-de-açúcar como matéria-prima para a produção de bioenergia vem crescendo consideravelmente. No entanto, a remoção excessiva da palha pode afetar negativamente o funcionamento do solo. Portanto, o objetivo deste trabalho foi quantificar e caracterizar a solução ao longo do perfil sob níveis de remoção de palha da superfície do solo. Para isso, foi construído um sistema de lisímetros com colunas de 1, 20, 50 e 100 cm de solo, de textura franco argilo arenosa, proveniente de área comercial de cana-de-açúcar em Piracicaba-SP, Brasil. O experimento foi conduzido em área aberta, sujeito a precipitação e luz natural. Depois da estabilização do solo dentro dos tubos, foram adicionados os seguintes tratamentos: 0, 3, 6 e 12 Mg ha-1 de massa seca, representando 100 (solo nu), 75, 50 e 0% de intensidade de remoção de palha, respectivamente, sendo adicionados novamente após um ano. A solução percolada foi coletada e quantificada por 17 meses, a umidade do solo foi determinada por dois meses usando sensores. A concentração de carbono orgânico dissolvido (COD) foi mensurada com analisador automático. A solução do solo e solução da palha, feita por infusão em água, foram caracterizadas em HPLC para verificar a presença de compostos tóxicos. Posteriormente, as soluções da palha e solo foram usadas em testes de sementes de soja para avaliar os efeitos na germinação e crescimento inicial. Ao final do experimento, foram realizadas análises de densidade do solo e carbono orgânica do solo (COS). A palha remanescente foi pesada após um ano, anterior a nova adição, e pesada novamente ao final do experimento, para determinar a taxa de decomposição. O volume de solução percolado foi 30, 11 e 4% menor em 100, 75 e 50% do que em 0% de remoção, respectivamente. O solo descoberto armazenou menos água, indicando susceptibilidade à perda de água por evaporação. A simulação mostrou que 100 e 75% de remoção induzem longos períodos de restrição hídrica, que pode prejudicar o crescimento da planta. A produção de COD na camada superficial foi maior no solo sem remoção; a retenção foi maior de 1 a 20 cm em solo sem remoção, e maior em 20 a 50 cm em 50 e 75% de remoção. O solo descoberto liberou mais COD em de 20 cm do que em superfície, indicando perda de C. Abaixo de 100 cm, o COD lixiviado foi similar nos tratamentos, indicando grande retenção de C e pequenas perdas por lixiviação, mesmo em alta produção de COD. Mesmo com diferenças na retenção de COD, não foi identificado aumento no estoque de C abaixo de 5 cm. Foram encontrados compostos fenólicos na solução da palha, não encontrados na solução do solo, indicando que em condições naturais a palha não libera quantidades significativas de compostos tóxicos na solução do solo. O crescimento de plantas foi negativamente afetado pela solução da palha, mas não pela solução do solo. Nossos resultados sugerem que a manutenção de quantidade média de palha previne perdas e variação no conteúdo de água do solo. Maior quantidade de palha aumenta a produção de COD, que provavelmente altera sua composição, alterando a retenção no solo. O estoque de C não aumentou consideravelmente em subsuperfície, mas muito provavelmente aumentará em escala de tempo maior. Quanto maior a remoção de palha, proporcionalmente maior as taxas de C liberadas na forma de CO2 e COD em subsuperfície, consequentemente, menor a retenção de C no solo. Maiores quantidades de palha na superfície liberam mais C para o solo, retido ou translocado com a água, podendo ser estocado em maiores profundidades do solo. Maior percolação de água no solo não significa maiores perdas de C por lixiviação em profundidade.

Abstract (sommario):
Concerns about global warming and climate change have triggered a growing demand for renewable energy. In this scenario, the interest in using sugarcane straw as raw material for energy production has increased. However, straw plays an important role in maintaining soil quality. In addition, uncertainties as to produced straw amount and the straw removal impact on the stalk yield have raised doubts as to the use this raw material. In this sense, the objective this study was evaluate the short-term (2-year) the sugarcane straw removal impacts on soil and yield modeling of sugarcane stalk and straw, using soil attributes of different layers. Two experiments were carried out in São Paulo state, Brazil: one at Capivari (sandy clay loam soil) and another at Valparaíso (sandy loam soil). We have tested five rates of straw removal (i.e., equivalent to 0, 25, 50, 75 and 100 %). Soil samples were taken from 0-2.5, 2.5-5, 5-10, 10-20 and 20-30 cm layers to analyze pH, total C and N, P, K, Ca, Mg, bulk density and soil penetration resistance. Plant samples were collected to determine the straw and stalk yield. The impacts caused by straw removal differed between the areas, however, they concentrated on the more soil superficial layer. In sandy clay loam soil, straw removal led to organic carbon depletion and soil compaction, while in the sandy loam soil the chemical attributes (i.e. Ca and Mg contents) were the most impacted. In general, the results suggest that straw removal causes reduction more significant in soil quality for the sandy clay loam soil. The results indicate the possibility to remove about half-straw amount deposited on soil\'s surface (8.7 Mg ha-1 straw remaining) without causing severe implications on the quality of this soil. In contrast, although any amount of straw was sufficient to cause alterations the quality of the sandy loam soil, these impacts were less intense and are not magnified with the increase of straw removal. It was possible to model sugarcane straw and stalk yield using soil attributes. The 0-20 cm layer was the most important layer in the stalk yield definition, whereas the 0-5 cm layer, which the impacts caused by the straw removal were concentrated, was less important. Thus, we noticed that impacts caused to soil by straw removal have little influence on crop productivity. Straw prediction has proved more complex and possibly requires additional information (e.g crop and climate information) for good results to be obtained. Overall, the results suggest that the planned removal of straw for energy purposes can occur in a sustainable way, but should take into account site conditions, e.g soil properties. However, long-term research with different approaches is still necessary, both to follow up and confirm our results, and to develop ways to reduce damage caused by this activity.
Preocupações acerca do aquecimento global e mudanças climáticas tem provocado uma crescente demanda por energias renováveis. Nesse cenário, tem aumentado o interesse em utilizar a palha de cana-de-açúcar como matéria prima para produção de energia. Contudo, a palha desempenha importante papel na manutenção da qualidade do solo. Aliado a isso, incertezas quanto a quantidade de palha produzida e o impacto da remoção da palha na produção de colmos tem levantado duvidas quanto ao uso dessa matéria prima. Nesse sentido, o objetivo desse estudo foi avaliar a curto prazo (2 anos) os impactos da remoção da palha de cana-de-açucar no solo, e modelar a produção de palha e colmo de cana-de-açucar utilizando atributos do solo de diferentes camadas. Para tanto, foram conduzidos dois experimentos nos municípios de Capivari (solo de textura média) e Valparaíso (solo de textura arenosa), estado de São Paulo, Brasil. Foram testados cinco taxas de remoção de palha (i.e., equivalentes a 0, 25, 50, 75 e 100 %). Amostras de solo foram coletadas nas camadas 0-2,5, 2,5-5, 5-10, 10-20 e 20-30 cm de profundidade para determinação de C, N, pH, P, K, Ca, Mg, densidade do solo e resistência do solo a penetração. Amostras de planta foram coletadas para determinar a produção de colmo e palha. Os impactos causados pela remoção da palha diferiu entre as áreas, no entato, se concentraram na camada mais superficial do solo. No solo de textura média a remoção da palha levou a depleção do carbono orgânico e a compactação do solo, enquanto que, no solo de textura arenosa os atributos químicos (i.e teores de Ca e Mg) foram os mais impactados. Os resultados indicam a possibilidade de remover cerca de metade da quantidade de palha depositada sobre o solo (8.7 Mg ha-1 palha remanecente) sem causar graves implicações na qualidade deste solo. Em contraste, no solo de textura arenosa, qualquer quantidade de palha foi suficiente para causar alterações na qualidade do solo, contudo, essas alterações foram menos intensas e não aumentaram com as taxas de remoção da palha. Foi possível modelar a produção de colmo e palha de cana-de-açucar utilizando atributos do solo. A camada 0-20 cm foi a mais importante na definição da produção de colmos, ao passo que a camada 0-5 cm, camada em que se concentra os impactos causados pela remoção da palha, foi menos importante. Assim, notamos que os impactos causados ao solo pela remoção da palha tem pouca influencia na produtividade da cultura. A predição da palha se mostrou mais complexa e possivelmente requer informações adicionas (e.g informações da cultivar e de clima) para que bons resultados sejam obtidos. No geral, os resultados sugerem que a remoção planejada da palha para fins energéticos pode ocorre de maneira susutentável, porém deve levar em conta condições locais, e.g propriedades do solo. Contudo, pesquisas de longo prazo com diferentes abordagens ainda são necessárias, tanto para acompanhar e confirmar nossos resultados, como para desenvolver soluções que atenuem os danos causados por esta atividade.

Abstract (sommario):
This book illustrates the main results deriving from fourteen studies, dealing with the impact of climate change on different agricultural and natural ecosystems, carried out within the Impact of Climate change On agricultural and Natural Ecosystems (ICONE) project funded by the ALFA Programme of the European Commission. During this project, a common methodology on several Global Change-related matters was developed and shared among members of scientific communities coming from Latin America and Europe. In order to facilitate this interdisciplinary approach, specific mobility programmes, addressed to post-graduate, Master and PhD students, have been organized. The research, led by the research groups, was focused on the study of the impact of climate change on various environmental features (i.e. runoff in hydrological basins, soil erosion and moisture, forest canopy, sugarcane crop, land use, drought, precipitation, etc). Integrated and shared methodologies of atmospheric physics, remote sensing, eco-physiology and modelling have been applied.

Abstract (sommario):
Our capacity to maintain world food production depends heavily on the thin layer of soil covering the Earth's surface. The health of this soil determines whether crops can grow successfully, whether a farm business is profitable and whether an enterprise is sustainable in the long term. Farmers are generally aware of the physical and chemical factors that limit the productivity of their soils but often do not recognise that soil microbes and the soil fauna play a major role in achieving healthy soils and healthy crops. Soil Health, Soil Biology, Soilborne Diseases and Sustainable Agriculture provides readily understandable information about the bacteria, fungi, nematodes and other soil organisms that not only harm food crops but also help them take up water and nutrients and protect them from root diseases. Complete with illustrations and practical case studies, it provides growers and their consultants with holistic solutions for building an active and diverse soil biological community capable of improving soil structure, enhancing plant nutrient uptake and suppressing root pests and pathogens. The book is written by scientists with many years' experience developing sustainable crop production practices in the grains, vegetable, sugarcane, grazing and horticultural industries. This book will be useful for: growers, consultants, agronomists and soil chemists, extension personnel working in the grains, livestock, sugarcane and horticultural industries, professionals running courses in soil health/biological farming, and students taking university courses in soil science, ecology, microbiology, plant pathology and other biological sciences.

Abstract (sommario):
Biomass-based energy has characteristics that could help Maui Island meet multiple long-term goals, including decreasing reliance on oil for electricity and transportation fuels, increasing use of local resources that do not need to be shipped long distances, and diversifying the island economy beyond tourism by preserving agriculture. Biomass can be used for liquid fuel production and for electricity production. On Maui, sugarcane has been grown at plantation scale for over a century. Accordingly, sugarcane-derived ethanol and combustible sugarcane bagasse have long been of interest as energy sources for the island. State and county level focus on increasing renewable energy utilization on Maui have renewed study of potential crops and available land, with a special emphasis on sugarcane. However, there is some concern about the water requirements associated with biomass-based energy. A primary motivation for using local, renewable energy sources is that Maui is an island with limited resources, fresh water among them: thus, exploring ways to increase energy sustainability without compromising water availability is of interest to many. This work examines the water needs associated with growing sugarcane for ethanol and combustible biomass on Maui Island. Virtually all sugarcane on Maui is irrigated because soil and sunlight resources do not generally coincide with natural precipitation patterns. Growing sugarcane for energy represents a large water demand that is limiting under certain development scenarios on Maui, such as a scenario where environmental streamflows are highly prioritized. By comparing the irrigation demand of Maui’s currently grown sugarcane with published figures for ethanol yield from cane, this work finds that 700 to 1,500 gallons (gal) of irrigation water are needed per gallon of sugarcane-based ethanol (from fermentable sugars and fiber; 0.7 to 1.5 cubic meters, m3, per liter, L). More water is needed for processing. However, combustible waste streams could provide additional energy return per unit of water. This paper discusses how water demand for sugarcane-based energy interacts with other island water demands, given that about 37,000 acres (150 km2) of sugarcane land are potentially available for bioenergy production. Though seawater cannot be successfully directly used for irrigation, sugarcane can tolerate some salinity and other contamination, so this paper also considers brackish water and treated wastewater — for which there is little other demand — as potential irrigation resources. Notably, the range of tolerable water quality expands significantly when sugarcane is not intended for human ingestion or when biomass yield, not sugar content, is targeted (as for cellulosic ethanol or combustible biomass production).

Abstract (sommario):
Soft clay is a natural soil that spreads in the south of Iraq and many countries in the world. It is a problematic soil causing trouble for the structures built on it because of, high water content, low shear strength, and high compressibility. This work investigated the geotechnical behavior of soft clay by using mix of Metakaolin (M) and Sugarcane Straw Ash in air (SCSAA).The experimental work contains the following tests: chemical tests, physical tests, Compaction tests and shear test. These tests were carried out on soil samples prepared from soft soil; the replacement materials by weight of dry unit weight for different percentages of M (4%, 6%, 8%, 10%) mix with different percentages of SCSAA (4%, 6%, 8%, 10%). The tests results showed that the best percentage for the plasticity test was M1B4. Also,the percentage which gave the best value for undrained shear strength test was M4B4 (135).Finally, the treatment soil is good sub grade materials and also can be used in highway sub-base material.
