Conservation agriculture: implementation guidance for policymakers and investors

imgCA Conservation agriculture is an approach to agricultural management based on three principles: (i) Minimum soil disturbance (ii) Retention of crop residues or other soil surface cover (iii) Use of crop rotations.
