Conservative agriculture greatly reduces soil erosion and actually builds up soil organic matter reserves and soil fertility. CA has been successfully adapted to work for cultivating a wide variety of crops such as soybean, groundnut, pigeonpea, sugar cane, potatoes, beets, cassava, other vegetables and pulses, and several perennial fruit and vine species. The principles of minimal soil disturbance, permanent soil cover and rotations work for all crops.
Conservation agriculture has three principles (i) minimum soil disturbance (ii) maintaining a 30% surface cover with cash or cover crop residues (iii) legume-based crop rotation.
It has 3 aspects: 1. As a farmer to do CA in his farm; 2. As an performance expert to encourage farmers to perform CA in their farms and 3. As a researcher to select his priority to assess in CA;
