Update study on agrarian changes and the status of conservation agriculture in southern Sayaboury, 2015

The cropping systems experimented and disseminated by the PRONAE and PASS projects and the CADF are all gathered under the broad concept of Direct seeding Mulch-based Cropping (DMC) systems. DMC systems are cropping systems that involve no tillage and a permanent plant cover ofthe soil. The expression ‘plant cover’ further refers to dead mulch (crop residue, cover plants or dead weeds) or live mulch associated with the crop.
