Amendement du sol avec des rameaux d'arbres au Burkina Faso, le Lundi 27 février à Ouagadougou
L'UMR Eco&Sols (Ecologie fonctionnelle et biogéochimie des sols et agrosystèmes ; Montpellier SupAgro-CIRAD-INRA-IRD), en partenariat avec l'Université de Ouagadougou et AgroParisTech, propose un séminaire de restitution de ses résultats sur l'amendement du sol avec des rameaux d'arbres au Burkina Faso. Ce séminaire a eu lieu le lundi 27 février 2012 au Centre IRD de Ouagadougou (688, av. Prof. Ki-Zerbo, Secteur 4) de 14h à 18h15 (informations auprès d'Edmond Hien). Ce séminaire a été suivi par visioconférence depuis le Centre IRD de Daka et depuis l'UMR Eco&Sols à Montpellier.
Les exposés du séminaire sont téléchargeables à partir de la page du projet BRF.

EUROSOIL 2012
L'UMR Eco&Sols co-organise plusieurs session du congrès EUROSOIL 2012 qui aura lieu à Bari (Juillet 2012)
Session S11.5 sur la décomposition des matières organiques dans les sols et les relations avec la diversité microbienne.
Organic matter decomposition: does soil diversity matter? Heterotrophic soil microbial biomass transforms soil and added organic matters under mineral forms available as nutrients and contribute also to soil organic matter builds up. These transformations are key processes also mediated by the soil biotic compartment like the microbiota. The role of soil organisms needs better understanding particularly to improve prediction and modeling of biogeochemical cycles in different agro-ecosystems (agriculture, forest, grassland, bioenergy crops etc…). The key topics in this session will cover functional links between dynamics of plant residue carbon, nitrogen, sulfur and phosphorus and biotic (mainly microbial) diversity in soils. Questions addressed include: To what extent soil microbial diversity affects nutrients turnover in soils ? How diversity of soil communities and organic matters degradation are linked (functional and taxonomic,)?; How plant residues amount, quality or location in soils control microbial biomass diversity and functioning? Is there a threshold of microbial soil diversity to fulfill nutrient recycling functions? Do we need to take into account the soil diversity in decomposition models of soil organic matter? This session will focus on plant residue/litter as sources of C, N, S and P and their transformations through faunal and microbial functioning. Different ecosystems are targeted in arable, forest and grassland soils under temperate and tropical conditions, cropped with annual or perennial plants. We aim at bringing together soil biologists, microbial ecologists, biogeochemists and modelers to answer the above mentioned questions. Key words: chemical quality of organic matter; soil biota diversity; plant residue decomposition

Session S4.5 : Modelling coupled and interactive processes in soil systems
Physical, chemical, biological and mechanical processes interact in soil systems in a complex way. In addition, exchange of water, matter and energy with the atmosphere via the vegetation and the ground water interfere with the soil processes. The objective of this symposium is to discuss the state-of-the art of conceptual and mathematical model approaches and applications dealing with coupled reactive transport and plant-soil interactions. The main focus is on integration of water, heat, solute and colloidal transport subject to biogeochemical equilibrium and kinetic reactions. In the same framework, coupling of plant interactions with soil (water, nutrients and contaminant uptake) using a process-based description is of particular interest. Topics of interest are: (i) conceptual and mathematical models for coupled phenomena such as the effect of unsaturated flow conditions on geochemical and plant-soil interaction parameters, or change in transport properties or plant parameters in response to change in geochemical state variables, (ii) parameterization and integrated sensitivity analysis to identify relevant processes and parameters, (iii) application and validation of such models in contaminant transport, soil degradation, soil remediation, anthropogenic effects on soil, pedogenese.
