LAND ROTATION / BUSH FALLOWING
It involves growing crops on a piece of land until it is exhausted and the land is left to fallow for some years before it is used again.
Under this system, the land is used for 3-4 years after which it is left to revert to bush. The reason for this is to allow the land to rest and regains its lost nutrients.
The time land the land is left to regain its fertility is referred to as fallow period which may be between 4-8 years depending on the history of the land, population density and land availability.
