The study of different natural carbon sinks has become especially important because of climate change effects. The restoration of contaminated areas can be an ideal strategy for carbon sequestration. The studied area was affected by toxic Aznalc\uffc3\uffb3llar mine spill in 1998. Restoration process of the contaminated area was based, mainly, on the use of two organic amendments: leonardite (LE) and biosolid compost (BC). The objective of this study was to verify whether the application of these amendments promotes the long\uffe2\uff80\uff90term carbon sequestration in this soil. Five treatments were established: untreated control, biosolid compost (doses 4 and 2) and leonardite (doses 4 and 2). The addition of amendments implied an improvement in soil quality that was directly related to the amendment dose: decrease in bulk density, increase in pH, higher respiration rates and an improvement in the stratification ratio. Dose\uffe2\uff80\uff90dependent changes in the molecular composition of soil organic matter were shown by nuclear magnetic resonance analysis. Both amendments promoted carbon retention, although because of the low mineralization rates of soil organic matter in LE treatments, the carbon storage was higher. The dosage effect on the carbon balance was more important in LE treatments, whereas in the BC treatments, the balance was similar for both doses. Our findings suggest that LE4 significantly increased the total organic carbon and it was the most suitable treatment for long\uffe2\uff80\uff90term carbon storage, because of its molecular composition rich in relatively stable aromatic and lignin\uffe2\uff80\uff90derived compounds.

In the Itasy region, AFS were introduced to improve farmers' livelihoods by diversifying income sources and to address problems related to soil degradation. Previous studies in the region have shown the potential of AFS to store organic carbon in the soil. In the present work, we carried out further studies to assess the main factors affecting SOC stocks in AFS. In 2014, we performed a soil sampling on 137 AFS farmers'plots to assess SOC stocks in different AFS. In 2018, a second sampling was carried out to calculate SOC storage rates using the diachronic approach on 30 most representative AFS. The results revealed that the factors 'age of the system' and 'type of organic inputs' significantly affected SOC stocks in AFS. SOC stocks increased significantly over time in AFS plots, benefiting from regular organic inputs such as manure and/or compost. In contrast, SOC stocks remained unchanged over time in AFS plots where no organic fertilization was used. Our study showed a substantial SOC storage up to 47 parts per thousand year(-1), mainly explained by regular additions of organic inputs to maintain soil fertility and crop production. However, to fully understand the process of SOC storage in this context, further works, such as the analysis of the link between organic matter quality and the SOC storage process, and the quantification of the share of soil carbon inputs derived from tree biomass should be undertaken.", "keywords": ["[SDV.SA.SF]Life Sciences [q-bio]/Agricultural sciences/Silviculture", "agro\u00e9cologie", "stockage", "petite exploitation agricole", "http://aims.fao.org/aos/agrovoc/c_330982", "[SDV.SA.SDS]Life Sciences [q-bio]/Agricultural sciences/Soil study", "910", "630", "Tropical", "syst\u00e8mes agroforestiers", "http://aims.fao.org/aos/agrovoc/c_7427", "C sequestration", "TreeTropical", "http://aims.fao.org/aos/agrovoc/c_1721", "http://aims.fao.org/aos/agrovoc/c_1301", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_4510", "http://aims.fao.org/aos/agrovoc/c_35657", "agroforesterie", "2.

We evaluated the role of two representative Cerrado Oxisols (350 and 650\u00a0g clay\u00a0kg\u22121) as sources or sinks of atmospheric C when managed under three tillage systems (conventional tillage (CT), reduced tillage (RT), and no-till (NT)) in 8- and 5-year long-term experiments. A literature review was also carried out and the mean C sequestration rates in no-till soils of tropical and subtropical regions of Brazil were calculated and compared with values for soils from temperate regions of the world. The original C stocks in 0\u201320\u00a0cm layer of soils under native Cerrado were higher in the clayey (54.0\u00a0Mg\u00a0ha\u22121) than in the sandy clay loam soil (35.4\u00a0Mg\u00a0ha\u22121), suggesting a higher physical stability of organic matter associated with variable clay minerals in the clayey Oxisol. The original C stocks of the native Cerrado soils appear not to have decreased after 23 years of conventional tillage in the sandy clay loam Oxisol, except when the soil had been subjected to erosion (15% loss of C), or after 25 years in the clayey Oxisol. Compared to conventionally tilled soil, the C stocks in no-till sandy clay loam Oxisol increased by 2.4\u00a0Mg\u00a0ha\u22121 (C sequestration rate\u00a0=\u00a00.30\u00a0Mg\u00a0ha\u22121\u00a0year\u22121) and in the clayey Oxisol by 3.0\u00a0Mg\u00a0ha\u22121 (C sequestration rate\u00a0=\u00a00.60\u00a0Mg\u00a0ha\u22121\u00a0year\u22121). The mean rate of C sequestration in the no-till Brazilian tropical soils was estimated to be 0.35\u00a0Mg\u00a0ha\u22121\u00a0year\u22121, similar to the 0.34\u00a0Mg\u00a0ha\u22121\u00a0year\u22121 reported for soils from temperate regions but lower than the 0.48\u00a0Mg\u00a0ha\u22121\u00a0year\u22121 estimated for southern Brazilian subtropical soils. Considering the large area (about 70 million hectares) of the Cerrado which is currently used and potentially available for cropland, the adoption of no-till systems could turn the Cerrado soils into a significant sink for atmospheric C and contribute to the mitigation of global climate change.", "keywords": ["Carbon sequestration", "2.

Global warming is accompanied by increasing water stress across much of our planet. We studied soil biological processes and changes in soil organic carbon (SOC) storage in 30 Hungarian oak forest sites in the Carpathian Basin along a climatic gradient (mean annual temperature (MAT) 9.6\uffe2\uff80\uff9312.1\uffc2\uffa0\uffc2\uffb0C, mean annual precipitation (MAP) 545\uffe2\uff80\uff93725\uffc2\uffa0mm) but on similar gently sloped hillsides where the parent materials are loess and weathered dust inputs dating from the end of the ice age. The purpose of this research was to understand how a drying climate, predicted for this region, might regulate long-term SOC sequestration. To examine the effects of decreasing water availability, we compared soil parameters and processes in three categories of forest that represented the moisture extremes along our gradient and that were defined using a broken-stick regression model. Soil biological activity was significantly lower in the driest (\uffe2\uff80\uff9cdry\uffe2\uff80\uff9d) forests, which had more than double the SOC concentration in the upper 30\uffc2\uffa0cm layer (3.28\uffc2\uffa0g C/100\uffc2\uffa0g soil\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.11 SE) compared to soils of the wettest (\uffe2\uff80\uff9chumid\uffe2\uff80\uff9d) forests (1.32\uffc2\uffa0g C/100\uffc2\uffa0g soil\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.09 SE), despite the fact that annual surface litter production in humid forests was\uffe2\uff80\uff89~\uffe2\uff80\uff8937% higher than in dry forests. A two-pool SOM model constrained to fit radiocarbon data indicates that turnover times for fast and slow pools are about half as long in the humid soil compared to the dry soil, and humid soils transfer C twice as efficiently from fast to slow pools. Enzyme activity and fungal biomass data also imply shorter turnover times associated with faster degradation processes in the soils of humid forests. Thermogravimetry studies suggest that more chemically recalcitrant compounds are accumulating in the soils of dry forests. Taken together, our results suggest that the predicted climate drying in this region might increase SOC storage in Central European mesic deciduous forests even as litter production decreases.

Aboveground herbage biomass and leaf litter production were not altered by elevated CO2 but root growth rate, as measured with the ingrowth core method, and root turnover were strongly stimulated by elevated CO2 particularly at low soil moisture contents during summer. Consequently, significantly more plant material was returned to the soil under elevated CO2 leading to an accumulation of coarse (> 1\u00a0mm) particulate organic matter (POM) but not of finer POM fractions. The accumulating POM exhibited a lower C/N ratio, which was attributed to the higher proportion of legumes in the pasture under elevated CO2. Only small changes were detected in the size and activity of the soil microbial biomass in response to the POM accumulation, suggesting that higher organic substrate availability did not stimulate microbial growth and activity despite the apparent lower C/N ratio of accumulating POM.

Increasing food demand coupled with climate change pose a great challenge to agricultural systems. In this review we summarize recent advances in our knowledge of how plants, together with their associated microbiota, shape rhizosphere processes. We address (molecular) mechanisms operating at the plant\uffe2\uff80\uff93microbe-soil interface and aim to link this knowledge with actual and potential avenues for intensifying agricultural systems, while at the same time reducing irrigation water, fertilizer inputs and pesticide use. Combining in-depth knowledge about above and belowground plant traits will not only significantly advance our mechanistic understanding of involved processes but also allow for more informed decisions regarding agricultural practices and plant breeding. Including belowground plant-soil-microbe interactions in our breeding efforts will help to select crops resilient to abiotic and biotic environmental stresses and ultimately enable us to produce sufficient food in a more sustainable agriculture in the upcoming decades.\u00a01\u00a0m depth and analyzed for soil organic carbon (SOC) and BC.

In topsoils BC vs. SOC accumulation was affected by management for Andosol, Alisols in China, and Vertisols. However, both flooding and crop-residue management seemed to control this. BC contents relative to SOC also differed between the reference soil groups, independent of management (p\u00a0<\u00a00.0001), yet were surprisingly constant within replicates. We conclude that BC co-accumulated with SOC in all soils. However, the overall storage of BC (1\u00a0m depth) was affected by a combination of soil group and management. Vertisols contained the largest BC stocks (17\u201319\u00a0t\u00a0ha\u2212\u00a01 in non-paddy and paddy fields), followed by Andosols and Alisols (6\u201310\u00a0t\u00a0BC\u00a0ha\u2212\u00a01 under paddy management; 3\u20138\u00a0t\u00a0ha\u2212\u00a01 under non-paddy management). The Gleysol and Fluvisol had the smallest BC stocks, independent of soil use (3\u20134\u00a0t\u00a0ha\u2212\u00a01). Aromatic N proportions increased to >\u00a050% of total N after combustion of rice straw. However, aromatic N was barely, or not detectable in soil, and there was no correlation to BC. We conclude that burned crop residues were not a major source for aromatic N in soil. BC and aromatic N showed no distinct relations to soil properties, such as the abundance of clay-sized minerals, and Al and Fe oxides. Differences in BC stocks between the soils were most pronounced in the subsoils, likely caused by physical processes, such as swelling and shrinking of clays and/or translocation by leaching. Climate and regional soil-adjusted management also affected BC accumulation, but this first snapshot indicates that global BC maps may be linked to global soil maps.", "keywords": ["2.

Cover crops play an increasingly important role in improving soil quality, reducing agricultural inputs and improving environmental sustainability. The main objectives of this critical global review and systematic analysis were to assess cover crop practices in the context of their impacts on nitrogen leaching, net greenhouse gas balances (NGHGB) and crop productivity. Only studies that investigated the impacts of cover crops and measured one or a combination of nitrogen leaching, soil organic carbon (SOC), nitrous oxide (N2O), grain yield and nitrogen in grain of primary crop, and had a control treatment were included in the analysis. Long\uffe2\uff80\uff90term studies were uncommon, with most data coming from studies lasting 2\uffe2\uff80\uff933\uffc2\uffa0years. The literature search resulted in 106 studies carried out at 372 sites and covering different countries, climatic zones and management. Our analysis demonstrates that cover crops significantly (p\uffc2\uffa0<\uffc2\uffa00.001) decreased N leaching and significantly (p\uffc2\uffa0<\uffc2\uffa00.001) increased SOC sequestration without having significant (p\uffc2\uffa0>\uffc2\uffa00.05) effects on direct N2O emissions. Cover crops could mitigate the NGHGB by 2.06\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.10\uffc2\uffa0Mg CO2\uffe2\uff80\uff90eq\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0year\uffe2\uff88\uff921. One of the potential disadvantages of cover crops identified was the reduction in grain yield of the primary crop by \uffe2\uff89\uff884%, compared to the control treatment. This drawback could be avoided by selecting mixed cover crops with a range of legumes and non\uffe2\uff80\uff90legumes, which increased the yield by \uffe2\uff89\uff8813%. These advantages of cover crops justify their widespread adoption. However, management practices in relation to cover crops will need to be adapted to specific soil, management and regional climatic conditions.

Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.

To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta\uffe2\uff80\uff90analysis with field measurements across a European\uffe2\uff80\uff90wide network of sites. In the meta\uffe2\uff80\uff90analysis, we related crop species averages of leaf N, leaf\uffe2\uff80\uff90dry matter content, fine\uffe2\uff80\uff90root C and N, with SOC stocks and sequestration responses in OF vs. CF. Across six European sites, we measured the management\uffe2\uff80\uff90induced changes in SOC stocks and leaf litter traits after long\uffe2\uff80\uff90term ecological intensive (e.g. OF) vs. CF comparisons.

Our global meta\uffe2\uff80\uff90analysis showed that the positive OF\uffe2\uff80\uff90effects on soil respiration, SOC stocks, and SOC sequestration rates were significant even in organic farms with low manure application rates. Although fertilization intensity was the main driver of OF\uffe2\uff80\uff90effects on SOC, leaf and root N concentrations also played a significant role. Across the six European sites, changes towards higher leaf litter N in CF also promoted lower SOC stocks.

Our results highlight that crop species displaying traits indicative of resource\uffe2\uff80\uff90acquisitive strategies (e.g. high leaf and root N) increase the difference in SOC between OF and CF. Indeed, changes towards higher crop residue decomposability was related with decreased SOC stocks under CF across European sites.

Synthesis and applications. Our study emphasizes that, with management, changes in crop residue traits contribute to the positive effects of organic farming (OF) on soil carbon sequestration. These results provide a clear message to land managers: the choice of crop species, and more importantly their functional traits (e.g. leave and root nitrogen), should be considered in addition to management practices and climate, when evaluating the potential of OF for climate change mitigation.

Nitrogen fertilizer and harvest management will alter soils under bioenergy crop production and the long\uffe2\uff80\uff90term effects of harvest timing and residue removal remain relatively unknown. Compared to no\uffe2\uff80\uff90tilled corn (NT\uffe2\uff80\uff90C, Zea mays L.), switchgrass (Panicum virgatum L.) is predicted to improve soil properties [i.e. soil organic C (SOC), soil microbial biomass (SMB\uffe2\uff80\uff90C), and soil aggregation] due to its perennial nature and deep\uffe2\uff80\uff90rooted growth form, but few explicit field comparisons exist. We assessed soil properties over 9\uffc2\uffa0years for a rainfed study of N fertilizer rate (0, 60, 120, and 180\uffc2\uffa0kg N\uffc2\uffa0ha\uffe2\uff88\uff921) and harvest management on switchgrass (harvested in August and postfrost) and NT\uffe2\uff80\uff90C (with and without 50% stover removal) in eastern NE. We measured SOC, aggregate stability, SMB\uffe2\uff80\uff90C, bulk density (BD), pH, P and K in the top 0\uffe2\uff80\uff9330\uffc2\uffa0cm. Both NT\uffe2\uff80\uff90C and switchgrass increased SMB\uffe2\uff80\uff90C, SOC content, and aggregate stability over the 9\uffc2\uffa0years, reflecting improvement from previous conventional management. However, the soils under switchgrass had double the percent aggregate stability, 1.3 times more microbial biomass, and a 5\uffe2\uff80\uff938% decrease in bulk density in the 0\uffe2\uff80\uff935 and 5\uffe2\uff80\uff9310\uffc2\uffa0cm depths compared to NT\uffe2\uff80\uff90C. After 9\uffc2\uffa0years, cumulative decrease in available P was significantly greater beneath NT\uffe2\uff80\uff90C (\uffe2\uff88\uff9224.0\uffc2\uffa0kg P\uffc2\uffa0ha\uffe2\uff88\uff921) compared to switchgrass (\uffe2\uff88\uff925.4\uffc2\uffa0kg P\uffc2\uffa0ha\uffe2\uff88\uff921). When all measured soil parameters were included in the Soil Management Assessment Framework (SMAF), switchgrass improved soil quality index over time (\uffce\uff94SQI) in all depths. NT\uffe2\uff80\uff90C without residue removal did not affect \uffce\uff94SQI, but 50% residue removal decreased \uffce\uff94SQI (0\uffe2\uff80\uff9330\uffc2\uffa0cm) due to reduced aggregate stability and SMB\uffe2\uff80\uff90C. Even with best\uffe2\uff80\uff90management practices such as NT, corn stover removal will have to be carefully managed to prevent soil degradation. Long\uffe2\uff80\uff90term N and harvest management studies that include biological, chemical, and physical soil measurements are necessary to accurately assess bioenergy impacts on soils.

Belowground root biomass is infrequently measured and simply represented in models that predict landscape\uffe2\uff80\uff90level changes to soil carbon stocks and greenhouse gas balances. Yet, crop\uffe2\uff80\uff90specific responses to N fertilizer and harvest treatments are known to impact both plant allocation and tissue chemistry, potentially altering decomposition rates and the direction and magnitude of soil C stock changes and greenhouse gas fluxes. We examined switchgrass (Panicum virgatum L.) and corn (Zea mays L.,) yields, belowground root biomass, C, N and soil particulate organic matter\uffe2\uff80\uff90C (POM\uffe2\uff80\uff90C) in a 9\uffe2\uff80\uff90year rainfed study of N fertilizer rate (0, 60, 120 and 180\uffc2\uffa0kg\uffc2\uffa0N\uffc2\uffa0ha\uffe2\uff88\uff921) and harvest management near Mead, NE, USA. Switchgrass was harvested with one pass in either August or postfrost, and for no\uffe2\uff80\uff90till (NT) corn, either 50% or no stover was removed. Switchgrass had greater belowground root biomass C and N (6.39, 0.10\uffc2\uffa0Mg\uffc2\uffa0ha\uffe2\uff88\uff921) throughout the soil profile compared to NT\uffe2\uff80\uff90corn (1.30, 0.06\uffc2\uffa0Mg\uffc2\uffa0ha\uffe2\uff88\uff921) and a higher belowground root biomass C:N ratio, indicating greater recalcitrant belowground root biomass C input beneath switchgrass. There was little difference between the two crops in soil POM\uffe2\uff80\uff90C indicating substantially slower decomposition and incorporation into SOC under switchgrass, despite much greater root C. The highest N rate decreased POM\uffe2\uff80\uff90C under both NT\uffe2\uff80\uff90corn and switchgrass, indicating faster decomposition rates with added fertilizer. Residue removal reduced corn belowground root biomass C by 37% and N by 48% and subsequently reduced POM\uffe2\uff80\uff90C by 22% compared to no\uffe2\uff80\uff90residue removal. Developing productive bioenergy systems that also conserve the soil resource will require balancing fertilization that maximizes aboveground productivity but potentially reduces SOC sequestration by reducing belowground root biomass and increasing root and soil C decomposition.

Under elevated atmospheric CO2 concentrations, soil carbon (C) inputs are typically enhanced, suggesting larger soil C sequestration potential. However, soil C losses also increase and progressive nitrogen (N) limitation to plant growth may reduce the CO2 effect on soil C inputs with time. We compiled a data set from 131 manipulation experiments, and used meta\uffe2\uff80\uff90analysis to test the hypotheses that: (1) elevated atmospheric CO2 stimulates soil C inputs more than C losses, resulting in increasing soil C stocks; and (2) that these responses are modulated by N. Our results confirm that elevated CO2 induces a C allocation shift towards below\uffe2\uff80\uff90ground biomass compartments. However, the increased soil C inputs were offset by increased heterotrophic respiration (Rh), such that soil C content was not affected by elevated CO2. Soil N concentration strongly interacted with CO2 fumigation: the effect of elevated CO2 on fine root biomass and \uffe2\uff80\uff93production and on microbial activity increased with increasing soil N concentration, while the effect on soil C content decreased with increasing soil N concentration. These results suggest that both plant growth and microbial activity responses to elevated CO2 are modulated by N availability, and that it is essential to account for soil N concentration in C cycling analyses.

Soil management practices that result in increased soil carbon (C) sequestration can make a valuable contribution to reducing the increase in atmospheric CO2 concentrations. We studied the effect of poultry manure, cattle slurry, sewage sludge, NH4NO3 or urea on C cycling and sequestration in silage grass production. Soil respiration, net ecosystem exchange (NEE) and methane (CH4) fluxes were measured with chambers, and soil samples were analysed for total C and dissolved organic C (DOC). Treatments were applied over 2\uffe2\uff80\uff83years and measurements were carried out over 3\uffe2\uff80\uff83years to assess possible residual effects. Organic fertilizer applications increased CO2 loss through soil respiration but also enhanced soil C storage compared with mineral fertilizer. Cumulative soil respiration rates were highest in poultry manure treatments with 13.7\uffe2\uff80\uff83t\uffe2\uff80\uff83C\uffe2\uff80\uff83ha\uffe2\uff88\uff921 in 2003, corresponding to 1.6 times the control value, but no residual effect was seen. Soil respiration showed an exponential increase with temperature, and a bimodal relationship with soil moisture. The greatest NEE was observed on urea treatments (with a CO2 uptake of \uffe2\uff88\uff924.4\uffe2\uff80\uff83g CO2\uffe2\uff80\uff83m\uffe2\uff88\uff922\uffe2\uff80\uff83h\uffe2\uff88\uff921). Total C and DOC were significantly greater in manure treatments in the soil surface (0\uffe2\uff80\uff9310\uffe2\uff80\uff83cm). Of the C added in the manures, 27% of that in the sewage pellets, 32% of that in the cattle slurry and 39% of that in the poultry manure remained in the 0\uffe2\uff80\uff9310\uffe2\uff80\uff83cm soil layer at the end of the experiment. Mineral fertilizer treatments had only small C sequestration rates, although uncertainties were high. Expressed as global warming potentials, the benefits of increased C sequestration on poultry manure and sewage pellet treatments were outweighed by the additional losses of N2O, particularly in the wet year 2002. Methane was emitted only for 2\uffe2\uff80\uff933\uffe2\uff80\uff83days on cattle slurry treatments, but the magnitudes of fluxes were negligible compared with C losses by soil respiration.

Among the organic waste materials produced by agricultural and industrial activities, olive mill wastes derived from the olive oil extraction process may represent a suitable soil amendment. The aim of the study was to evaluate the effect of fresh (SOMW) or composted mixture of SOMW and shredded olive tree prunings (C-SOMW+P) on the vegetative and productive activities of olive trees, on the C stored in the tree non-permanent structures (prunings and fruits) and in the soil. The plots treated with SOMW or C-SOMW+P showed higher vegetative and productive activities than the untreated plots, and this was attributed to the higher total N and availability of P and K supplied by the amendments. Consequently, treatments increased the C sequestered in the tree non-permanent structures than in the control trees. However, no significant different effect between SOMW and C-SOMW+P treatments was found for the C stored in prunings and fruits, whereas it was evident a stronger influence of C-SOMW+P than SOMW on soil C sequestration. Indeed, about 50% the C supplied by the treatment with C-SOMW+P was sequestered in the olive grove system, with more than 90% of the sequestered C stored into the soil. The low amount of C sequestered in the soil following the addition of SOMW was attributed to its richness of moisture and easily degradable compounds that triggered the mineralization processes controlled by the soil microbial community. Although the 8 years of amendment produced a higher fruit yields than the control, no difference occurred between the characteristics and the oil content of the olive fruits.

The possibility of reducing greenhouse gas (GHG) emissions by ruminants using improved grazing is investigated by estimating GHG emissions for cow-calf farms under light continuous (LC), heavy continuous (HC) and rotational grazing, also known as multi-paddock (MP), management strategies in Southern Great Plain (SGP) using life cycle assessment (LCA).

Abstract. Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata plantation (PINUS). Total carbon content of the 0-10cm soil layer was higher for GRASS (6.7 kg C m-2) than for PINUS (4.3 kg C m-2, while TC content of SGFOR (5.8 kg C m-2) was not significantly different from either one. High extractable oxalate and pyrophosphate Al concentrations (varying from 20.3-24.4 g kg-1, and 3.9-11.1 g kg-1, respectively) were found in all sites. In this study, SOC and aggregate dynamics were studied using size and density fractionation experiments of the SOC, \uffce\uffb413C and total carbon analysis of the different SOC fractions, and C mineralization experiments. The results showed that electrostatic sorption between and among amorphous Al components and clay minerals is mainly responsible for the formation of metal-humus-clay complexes and the stabilization of soil aggregates. The process of ligand exchange between SOC and Al would be of minor importance resulting in the absence of aggregate hierarchy in this soil type. Whole soil C mineralization rate constants were highest for SGFOR and PINUS, followed by GRASS (respectively 0.495, 0.266 and 0.196 g CO2-Cm-2d-1 for the top soil layer). In contrast, incubation experiments of isolated macro organic matter fractions gave opposite results, showing that the recalcitrance of the SOC decreased in another order: PINUS>SGFOR>GRASS. We deduced that electrostatic sorption processes and physical protection of SOC in soil aggregates were the main processes determining SOC stabilization. As a result, high aggregate carbon concentrations, varying from 148 till 48 g kg-1, were encountered for all land use sites. Al availability and electrostatic charges are dependent on pH, resulting in an important influence of soil pH on aggregate stability. Recalcitrance of the SOC did not appear to largely affect SOC stabilization. Statistical correlations between extractable amorphous Al contents, aggregate stability and C mineralization rate constants were encountered, supporting this hypothesis. Land use changes affected SOC dynamics and aggregate stability by modifying soil pH (and thus electrostatic charges and available Al content), root SOC input and management practices (such as ploughing and accompanying drying of the soil).

Global warming is accompanied by increasing water stress across much of our planet. We studied soil biological processes and changes in soil organic carbon (SOC) storage in 30 Hungarian oak forest sites in the Carpathian Basin along a climatic gradient (mean annual temperature (MAT) 9.6\uffe2\uff80\uff9312.1\uffc2\uffa0\uffc2\uffb0C, mean annual precipitation (MAP) 545\uffe2\uff80\uff93725\uffc2\uffa0mm) but on similar gently sloped hillsides where the parent materials are loess and weathered dust inputs dating from the end of the ice age. The purpose of this research was to understand how a drying climate, predicted for this region, might regulate long-term SOC sequestration. To examine the effects of decreasing water availability, we compared soil parameters and processes in three categories of forest that represented the moisture extremes along our gradient and that were defined using a broken-stick regression model. Soil biological activity was significantly lower in the driest (\uffe2\uff80\uff9cdry\uffe2\uff80\uff9d) forests, which had more than double the SOC concentration in the upper 30\uffc2\uffa0cm layer (3.28\uffc2\uffa0g C/100\uffc2\uffa0g soil\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.11 SE) compared to soils of the wettest (\uffe2\uff80\uff9chumid\uffe2\uff80\uff9d) forests (1.32\uffc2\uffa0g C/100\uffc2\uffa0g soil\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.09 SE), despite the fact that annual surface litter production in humid forests was\uffe2\uff80\uff89~\uffe2\uff80\uff8937% higher than in dry forests. A two-pool SOM model constrained to fit radiocarbon data indicates that turnover times for fast and slow pools are about half as long in the humid soil compared to the dry soil, and humid soils transfer C twice as efficiently from fast to slow pools. Enzyme activity and fungal biomass data also imply shorter turnover times associated with faster degradation processes in the soils of humid forests. Thermogravimetry studies suggest that more chemically recalcitrant compounds are accumulating in the soils of dry forests. Taken together, our results suggest that the predicted climate drying in this region might increase SOC storage in Central European mesic deciduous forests even as litter production decreases.Increasing food demand coupled with climate change pose a great challenge to agricultural systems. In this review we summarize recent advances in our knowledge of how plants, together with their associated microbiota, shape rhizosphere processes. We address (molecular) mechanisms operating at the plant\uffe2\uff80\uff93microbe-soil interface and aim to link this knowledge with actual and potential avenues for intensifying agricultural systems, while at the same time reducing irrigation water, fertilizer inputs and pesticide use. Combining in-depth knowledge about above and belowground plant traits will not only significantly advance our mechanistic understanding of involved processes but also allow for more informed decisions regarding agricultural practices and plant breeding. Including belowground plant-soil-microbe interactions in our breeding efforts will help to select crops resilient to abiotic and biotic environmental stresses and ultimately enable us to produce sufficient food in a more sustainable agriculture in the upcoming decades.
