Conservation agriculture (CA) is a crop management system based on three principles: 1) minimum soil movement (i.e., no soil inversion by tillage); 2) soil surface cover with crop residues and/or living plants; and 3) diversification through crop rotation and intercropping.

Besides these three main principles, CA depends on good agricultural practices (e.g., adequate fertilization, weed control, timely planting, and improved varieties) to show its greatest benefits. Most crops can be grown successfully under CA in Africa and there are large areas of maize, cowpea, soybean, groundnut, cotton, sunflower, and many other crops grown under this system. Even root crops, inclu….
