Mineralisation of crop residues on the soil surface or incorporated in the soil under controlled conditions


Abiven, S; Recous, S (2007). Mineralisation of crop residues on the soil surface or incorporated in the soil under controlled conditions. Biology and Fertility of Soils, 43(6):849-852.

Abstract

In the present work, we compare the effect of mature crop residues mixed into a ferralitic soil or placed as a single layer on soil surface on the mineralisation of C and N over 55 days. As residues, we used dry stems of rice, soybean, sorghum, brachiaria and wheat. There were no significant effects of residue placement on C mineralisation kinetics. Decomposition of the residues on the soil surface slightly increased net N mineralisation for residues having the smallest C/N ratio.
