Der volle Inhalt der QuelleForest ecosystems often grow on acidic, nutrient-poor soils. In many places, high acidic atmospheric deposition (sulfuric and nitric acids) has significantly accelerated the acidification of soils and surface waters during the second half of the 20th century, frequently leading to soil fertility degradation and forest decline. In addition, species selection and/or substitution by forest management can also have a significant effect on the biogeochemical functioning of soils and forest ecosystems. In this context, their sustainability is questioned and it is necessary to quantify the evolution of the chemical fertility of forest ecosystems in the face of these pressures and to better understand their biogeochemical functioning, in order to ensure sustainable forest management. The main objectives of this thesis are i) to quantify the evolution of chemical fertility of forest ecosystems using four diagnosis methods: soil resampling, monitoring of soil solutions, foliar concentrations and calculation of the "input-output" budget, ii) to understand the mechanisms underlying this evolution and iii) to compare the results obtained by the different methods, taking into account the uncertainty surrounding the budget. To do this, we quantified the evolution of fertility over a period of 20 to 30 years by these 4 methods, on monospecific plots of the Breuil-Chenue site and on 8 level III plots of the RENECOFOR network. The results showed that the species had an effect on soil acidification and on the pools of exchangeable nutritive cations in the soil. Hardwoods appear to acidify soils less intensely than coniferous. A restoration of pH is observed under oak and beech, whereas acidification seems to continue under coniferous, especially under Douglas fir and pine, and even more under Nordmann fir and spruce. Soil acidification and associated nutrient losses have also been demonstrated on some RENECOFOR sites. Nitrate and sulphate seem to be the main drivers of acidification. However, their origin depends on the site studied: they are sometimes derived from current atmospheric deposition, but internal sources to the ecosystem may also intervene via excess nitrification (especially under Douglas fir, pine, oak at Breuil and CPS 77) or desorption of S into the soil (especially on RENECOFOR sites). Leaching of S and N and associated cations tends to acidify soils. However, the response of sites to acidification can vary, depending on the predominance of either biological or geochemical cycling. Sites identified with predominant geochemical cycling (CHS 41, CPS 77, HET 30, and SP 38) have nutrient pools supported more by weathering and atmospheric deposition fluxes, whereas the sites dominated by biological cycling (EPC 08, EPC 87, PS 67a, SP 57) have nutrient pools supported primarily by recycling fluxes. Finally, the results showed that the comparison between the different fertility diagnosis methods is not easy. Differences were highlighted, with sometimes contradictory results. Taking into account the uncertainty around the budget does not alone explain the differences observed by the soil resampling approach. Uncertainty in the choice of model could perhaps partly explain the origin of the discrepancies. This work highlights the importance of continuing research on i) understanding the response of forest ecosystems to changes in atmospheric deposition and species substitution and ii) assessing the uncertainties surrounding the different approaches to fertility diagnosis

Der volle Inhalt der QuelleIn view of the depletion of primary resources and the increase in global waste production, the concept of agromining proposes phytoextracting the metals contained in abandoned materials. The solution proposed in this concept is inspired by Nature (NbS) and the principles of agronomy and is part of a circular economy. Thus, hyperaccumulator plants (HA) are able to collect metals from their root system and to store them at high concentrations in their aerial parts. The challenges of the thesis are to give value to waste or secondary materials by extracting the elements of interest that they contain and to identify the plants able to develop on these media. The objective is to formulate, from the chosen materials, a functional substrate, that is to say, capable of rendering a Ni supply service. From this point of view, the substrate must allow the installation and the development of the HAs in order to transfer the metals to the aerial parts. The work focuses on an acid phosphating sludge essentially composed of Fe, Zn, P and Mn and containing 0.5% Ni. Germination and growth tests were carried out with different substrates prepared from this sludge assembled with a soil sample mixture. The retained substrate consists of 10% sludge and 90% soil (w/w). On the latter, HA Alyssum murale produces a higher biomass compared to a control soil (ultramafic soil at the same pH and containing the same amount of bioavailable Ni), despite signs of toxicity to plants. One of the major locks is the high toxicity due to the presence of 6% Zn in the sludge. Two ways of improving the substrate are tested: i) the use of amendments and ii) the arrangement of materials in the profile. The most efficient amendment is a wood biochar; it improves the development of plants and thus the amount of phytoextracted Ni. In addition, by modifying the layout of the materials within the profile by a layered distribution, biomass production and phytoextraction are improved. This device makes it possible to remove Zn-related toxicity. It is essential to control the pH of the substrate during multi-contamination because the immobilization of the metal varies according to the element. The association of soil engineering and plant engineering has made it possible to formulate a functional substrate for the recovery of elements of interest such as Ni. This work demonstrates the possibility of upgrading by-products conventionally called "waste" in order to obtain a surplus value, also reducing their metallic charge and bringing about a new source of "plant-derived" metals obtained by agromining

Der volle Inhalt der QuelleCommunity gardens (e.g. allotments, shared gardens) currently experience a renewed interest among the French and are often associated with many functions and services within urban ecosystems (vegetable supply, biodiversity). As such, garden soils are a major concern and their characteristics (physico-chemical as well as biological ones) need to be better understood. What connection is there between the functional quality of garden soils and the alteration of their physico-chemical characteristics by gardening practices? What influence do these properties in garden soils have on functional and taxonomic biodiversity? In order to answer these questions, investigations were conducted in vegetable gardens chosen as representative of the ecosystemic variability within French territory. On one hand work was done on the topsoil's agronomical properties and toxicity. On the other hand these soils were characterised using several biological indicators, such as vegetal species and soil microarthropods. With the help of several databases, we were able to place these garden soils among other french topsoils by comparing them to other land uses. Despite having high total metallic contents garden soils show an undeniable physico-chemical fertility, and support a high level of soil biodiversity. In contrast, an increasing plant biotic homogenisation can be observed within cities. Indeed, there is a selection of species with traits that are particularly adapted to urban environments. In conclusion, even though garden soils exist in a highly anthropised urban context they are not degraded ecosystems, but rather a precious resource

Der volle Inhalt der QuelleTwo forest ecosystems in Lorraine, France (Clermont-en-Argonne CA and Azerailles AZ) developed on polycyclic soils have a complex functioning due to the presence of two different materials within the soil profile, leading to an abrupt disruption in soil texture. Indeed, they have low exchangeable Ca and Mg stocks in the silty soil upper layers (with a greater poverty in CA than in AZ), and very large stocks in deep clayey layers. These differences in upper soil fertility between the studied sites can be partly explained by a weaker aggregation in CA than in AZ (with aggregates poor in organic matter and clays). The CA soil then holds less nutrients than AZ one, despite higher atmospheric inputs and more rapid mineralization of litter. The richness of the deep soil layers in both sites, cannot be explained by the two conventional inputs i.e. atmospheric deposition and mineral weathering, A third un-expected source was identify using Sr, Ca and Mg isotopes, i.e. a mineralized groundwater table, which allows the CEC recharging of the deep clay layers by simple ion exchange when its invades the subsoil during the winter period. Trees have developed an uptake strategy into these Ca and Mg rich clay layer, to overcome the relative poverty of the upper soil layers. However the consequence of the Mg limititation of the soil upper layers in CA is visible through the increase in the internal Mg-translocation before leaf senescence

Der volle Inhalt der QuelleShifting cultivation on brulis (ai) is a convenient method of cultivation without inputs. After two or three crop cycles, the degradation of soil fertility forces farmers to move their crops and the land is left fallow. Fallowing can be used to reconstitute a biomass, which will release during the next production period, after burning, the mineral elements necessary for the growth and development of crops. The purpose of this study was to provide support for the decision, with a view to eventually establishing these traditional systems. It required an analysis of the management of Qi systems, an important component of reproducibility of fertility, and the condition of fixation. At first, the spatial management of these systems and their capacity to cope with the agro-ecological and socio-economic constraints of the environment, to reproduce, were studied. This study was carried out at the scale of the agrarian system and more precisely at the level of the production systems which correspond to the level of the choices and decisions of the farmers. In a second step, the evolution of the components of fertility, likely to influence the yield of cassava, was analyzed - the cassava constituting the main crop of West Guiana. Three levels were considered: the cropping system that allows to understand the modes of behavior and association of crops, but especially the cultivated plot and the experimental plot, place of measurement and monitoring. In the first stage of this work, a balancing capacity of the giblets is established from the Piaget model. This typology makes it possible to identify 5 functional types of giblets in the region and 2 modes of evolution. In the second stage, during a first cycle of giblets, after secondary forest, the evolution of stocks of carbon, nitrogen and exchangeable bases shows that there is no degradation in relation to the material organic soil. On the other hand, there is a decrease in exchangeable bases following the cultivation and in particular potassium. Comparing this decrease with the needs of the crop, it was possible to identify potassium as a factor limiting production

Der volle Inhalt der QuelleIn the sahelian zone, sail organic matter (SOM) and microbial biomass (MBc) are two essential components of soil fertility, SOM because of it's role in sail physical properties and stock of nutrients, and MBc as the key of most of the biological processes involved in SOM evolution. Our objective is (1) to evaluate the effects of organic inputs on sail fertility, using chemical and biological variables as well as yield components and (2) to determine the relationships between these variables so as to define types of soil behaviour that could explain the large variability of the response to manure in field conditions. We worked on medium-term and annual experiments as weil as a multilocal experiment in field conditions. Our variables are soil physico-chemical caracteristics, MBc, nitrification determined in situ (Nitn1) and in controlled conditions (Nitpot) as the biological variables, and plant prùductivity as an integrative variable. Our results confirm the fast degradation of SOM the first year of cultivation after 15 years of herbaceous fallow (-40% C the first year). This study also presents new results : (1) it validate, in field conditions, the increase of MBc during the cultivation period observed by other authors in agronomical station and precises the relationships between soil biological component (MBc and Nitm) and chemical ones (CEC, SOM) ; (3) it shows that the variability of the soil and plant reponse to manure is a function of it's composition and of the ecological zone; this variability is used to define types of sail behaviour; (4) it shows that residual effects of manure is still sensible, even after two years, on yield and MBc. This work also led to methodological studies. Controlled conditions are necessary for a better knowledge of biological mecanisms

Der volle Inhalt der QuelleThis thesis, by measuring wood chemical content called dendrochemistry, tries to respond to some ecological questions linked to tree nutrition and bio-indication of environmental conditions. Methods based on X-rays spectrometry like SXRF (Synchrotron X-Ray Fluorescence) and EDS (Energy Dispersive Spectrometry), which are still scarcely used in dendrochemistry have been tested. First study, by EDS, showed that Ca and Mn wood and bark content of Beech (Fagus sylvatica L.) varied significantly with the soil type (calcareous vs acidic). Mn content was highly related to soil pH. These results suggest that wood and bark Mn content may be used as a nutritional proxy. Significant differences in wood chemical content between heart- and sapwood were measured for K. For Ca and Mn, these differences became significant depending on the soil type suggesting that the tree origin site could influence the temporal trends. Wood chemical composition, obtained by SXRF, of Rhizophora mucronata Lam., a Kenyan mangrove species, allowed us to detect an annual cyclicity for Br, Ca, Mn et Sr. These results, as if preliminary, are promising for the datation of tropical woods. The comparison of beech trees fertilized by NPKCa with controls showed a high significant effect of fertilization on wood mean concentrations in Br, Ca, Hg and K by SXRF. Hg and Br could be indicators of soil past fertilizations. The high inter-tree variability (Ca, K and Mn) at the temporal scale which is partly linked to differences in tree dominance status limits the possibilities to use this species as an indicator of past soils acidifications. For methodological aspects, these two methods presented results in agreement with classical methods like ICP
