International audience; The potential contributions of exogenous organic matters (EOMs) to soil organic C and mineral N supply depend on their C and N mineralization, which can be assessed in laboratory incubations. Such incubations are essential to

Publikováno v: Fourrages

La valorisation des travaux analytiques conduits par le CIRAD sur l'île de la Réunion au cours de la période 2005 à 2012 a permis de préciser les fournitures en azote associées à la minéralisation de l'azote organique en l'absence d'apport d'

International audience; The sensitivity of C and N mineralization in soil to water potential is mostly described in simulation models as a linear function independent of the pedoclimatic conditions. We hypothesized that water sensitivity could be sit

Increasing soil organic matter (SOM) is of primary importance for maintaining soil fertility and mitigating climate change. Leaving crop residues on top of soil is not always an efficient means of increasing SOM because (i) of the high mineralization

Publikováno v: European Journal of Soil Science

Changes in the carbon (C) and nitrogen (N) compartments that result from the addition of organic material (OM) to the soil are predicted by the transformation of added OM (TAO) model with three parameters: very labile (P′L) and stable (PS) fraction
