Their effect on carbon storage and composition need to be evaluated. Method: The study investigates soil from mesocosms cultivated with maize and amended with four different kinds of amendments: only mineral fertilizers (control), buffalo manure, compost or vermicompost as well as biochar. Results: All organic amendments showed a positive effect on soil carbon storage and significantly influenced soil organic matter quality. The presence of biochar increased lignin-derived compounds abundance as well as both plant and microbial sugar content of soil amended with vermicompost but had no effect in the case of control soil. Conclusion: Synergistic effects between plants and different organic amendments influence carbon storage and soil organic matter composition. specialized SOL DEGRADE FERTILITE DU SOL SOL CULTIVE MAIS AMENDEMENT DU SOL CARBONE AZOTE STOCK ENGRAIS ORGANIQUE ENGRAIS MINERAL COMPOST MATIERE ORGANIQUE ETUDE COMPARATIVE BIOCHAR SEQUESTRATION DU CARBONE VIET NAM ZONE TROPICALE 076AGRO05 068PEDAPP 5 2 155-168 2014 1758-3004 https://www.documentation.ird.fr/hor/fdi:010062828 10.1080/17583004.2014.912868 1758-3004 [F B010062828] https://www.documentation.ird.fr/hor/fdi:010062828 https://www.documentation.ird.fr/intranet/publi/depot/2014-09-01/010062828.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-09-01 2024-07-09 fdi:010062828 fre
