What is zero tillage management?

Zero tillage management require different skills to preserve higher yields. It combines various farming techniques, equipment, crop rotation practices, cover crop, fertilization and pesticide use to achieve better soil properties. Crop rotation eliminates soil weeds, pests and diseases. By rotating the crops on a multi-layer cycle, pests and disease amount will decrease due to the reduced food supply. Cover crops are used to control weeds, increase nutrients in the soil and to pull mobile nutrients back to the surface of the soil from the lower layers by growing plants with long roots.
