Is a form of agriculture, used especially in tropical Africa, in which an area or ground is cleared of vegetation and cultivated for a several years and then abandoned for a new area until its fertility has been naturally restored.
Shifting cultivation is a type of agricultural process in which you plant a crop in a plot, and when the season finishes (or when the productiveness of the given plot is low), you let the plot "rest" or you plant a different strategical crop (that can help the plot regain fertility) in that plot, which allows the plot to regain fertility.
Explanation:
This is a useful method since you do not have to invest money or time into compost, instead, you let the earths fertility come back naturally, which is the most ecological and natural method you could use, without breaking any vital cycles or anything similar.
