Zero tillage

Zero-tillage, or no-tillage or no-till, is designed to generate higher yields while reducing production costs, erosion, and inputs. Adopters of zero-tillage practices in South Asia, for the wheat crop following the rice crop, have reported wheat yields that are greater than or equal to yields obtained through conventional practices.

Zero-tillage practices primarily reduce carbon dioxide (CO2) emissions and save on water use by 25% compared with the conventional methods. The largest CO2 abatement is achieved through reduced diesel fuel consumption as plowing or harrowing before planting is not needed. Air pollution is also lessened because the no-till method discourages the burning of crop residue on the field.
