Clearing a plot of ground in a forest, especially in tropical areas, and planting crops on it for a few years (typically 2-5 years) until the soil is depleted of nutrients or the plot has been invaded by a dense growth of vegetation from the surrounding forest. Then a new plot is cleared and the process is repeated. The abandoned plot cannot successfully grow crops for 10-30 years.
See also slash-and-burn cultivation.
Cutting down trees and other vegetation in a patch of forest, leaving the cut vegetation on the ground to dry, and then burning it. The ashes that are left add nutrients to the nutrient-poor soils found in most tropical forest areas. Crops are planted between tree stumps. Plots must be abandoned after a few years (typically 2;5 years) because of loss of soil fertility or invasion of vegetation from the surrounding forest.
