Impacts of long-term cassava-based conservation agriculture systems on soil greenhouse gas emissions in Cambodia

This study examines how long-term cassava-based conservation agriculture systems affect soil greenhouse gas emissions in Cambodia. Drawing on experimental data since 2009, it compares conventional tillage with no-tillage systems that include cover crops and residue retention. The results show that conservation agriculture can improve the greenhouse gas balance by increasing soil carbon inputs and reducing emissions per unit of yield. The findings highlight the potential of integrated soil and crop management practices to reconcile productivity with climate mitigation in tropical farming systems.
