Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value-added crops with complementary marketing opportunities.
Crop residues are the left overs in the field after grains have been harvested. In the past, they were considered as waste but researches have shown that they have very high value in nutrient, erosion control, infiltration, carbon sequestration and many more. Crop residue should be left in the field instead of harvesting.
Minimum soil disturbance is the basic principle of CA which aims at improving soil physical and chemical properties, reduce soil compaction, water loss and erosion and establish satisfactory crop stand.
