Detailed explanation-1: -Policies favoring sedentary farming over nomadic herding can contribute to desertification. The majority of dryland areas (65%) are rangelands that are more suited to sustainable grazing than crop production.

Detailed explanation-2: -Conservation tillage means any minimal tillage system that leaves sufficient crop residue to cover the soil surface by at least 30%. No-till farming, in which the soil is left undisturbed by tillage and the residue is left on the soil surface, is the most effective soil conservation system.

Detailed explanation-3: -No-till farmers grow crops with minimal disturbance to their fields and the organisms that call them home. This builds healthier soils while reducing money spent on fuel and labor – a win-win. With harvest season winding down, you’re no doubt making an important decision for your working land.

Detailed explanation-4: -Zero tillage reduces cost of cultivation by nearly Rs 2, 500-3, 000/ha through reduction in cost of land preparation, and reduces diesel consumption by 50-60 litres per hectare. Zero tillage reduces water requirement of crop and the loss of organic carbon by oxidation.
