Conservation tillage, according to FAO, is a general term that has been defined as any sequence of tillage that reduces soil and water losses compared to conventional tillage.
▶ This tillage system does not invert the soil and maintains stubble on the surface depending on the system used to till the land, theoretically "any tillage or planting system that maintains at least 30% of the soil surface covered with residues after planting, to reduce water erosion.

Conservation tillage includes the types of tillage that are carried out on soils for their conservation and improvement, after correcting the physical factors of the soils, the selected tillage should contribute to the formation of an arable layer without physical, chemical or biological limitations that allow sustained crop responses.
The types of tillage used as conservationist systems of soil use and management are minimum or reduced tillage and no-tillage or direct seeding.
Reduced tillage refers to the cultivation of the entire soil area but with the elimination of one or more tillage compared to conventional tillage systems.
And depending on the implements used and the number of passes, reduced tillage can be classified as a conservation or non-conservation system depending on the stubble cover remaining at the time of planting.
