cultivo migratorio

cultivo migratorio

A farming system, common in the tropics, in which land is cleared, the debris burned, and crops grown for a relatively short period until yields decline. The land is then abandoned. The original land is cleared and cropped again after a uncontrolled fallow period of 3-20 years, usually when soil fertility has been naturally restored by woody vegetation.
