Abstract Climate and litter quality are primary drivers of terrestrial decomposition and, based on evidence from multisite experiments at regional global scales, universally factored into models. In contrast, soil animals considered key regulators local scales but their role larger is unresolved. Soil consequently excluded models organic mineralization processes. Incomplete assessment the roles stems difficulties manipulating invertebrate experimentally across large geographic gradients....
The Paris Agreement calls for limiting global warming below 2°C. "4 per 1000 Initiative: Soils food security and climate" was launched in 2015 to increase soil organic carbon sequestration with three objectives: mitigation of climate change, adaptation change improved security. One the challenges Initiative relates its feasibility contrasted biophysical, social economic environments, questioning adoption rate required new practices. We conducted participatory multi-stakeholder workshops...
Agroecology has multiple interpretations and goals, driven by social movements, political contexts, scientific needs. Agroecological transition processes generate tensions between movements institutionalisation processes. Researchers are thus caught two potentially contradictory tasks: (i) advising policy-makers (ii) supporting farmers stakeholders in their endogenous trajectories. Here, we review a reflexive workshop that explored how agroecology narratives challenge researchers when...
Acacia holosericea seedlings were planted in 1-l pots filled with a soil collected from an Australian plantation Southern Senegal. After 6 months of culture, mycorrhizosphere soil, roots, galls induced by root-knot nematodes and Rhizobium nodules sampled each pot. The diversity this bacterial group was characterized siderotyping (pyoverdine IsoElectric Focusing (IEF) analysis) restriction fragment length polymorphism (RFLP). effect these isolates on the establishment ectomycorrhizal...
Abstract SOMKO is a new simulation model of soil organic matter (SOM) dynamics aimed at predicting long‐term and short‐term SOM based on mechanistic approach focusing microbes as the key agents decomposition. partitioned into cohorts chemical quality pools (classified by age composition), microbial community processes are explicitly represented, C : N stoichiometric constraints accounted for through mechanism offer demand. The analysis equations shows that: (1) cannot decrease below N; (2)...
Summary An individual‐based model, called MIOR, was designed to assess hypotheses on the effect of spatial distribution organic matter and microbial decomposers soil carbon nitrogen dynamics. Two main types object were defined represent substrates. All these objects positioned in a 3D space. The exchange between various entities simulated. scenarios tested according degrees clustering microorganisms. results simulations highlighted ratio accessible dynamics biomass CO 2 release. This...
