Detailed explanation-1: -Slash and burn agriculture is a widely used method of growing food in which wild or forested land is clear cut and any remaining vegetation burned. The resulting layer of ash provides the newly-cleared land with a nutrient-rich layer to help fertilize crops.
Detailed explanation-2: -In slash and burn agriculture, the farmers cut down the trees of the forest and burn the plant remains and the land is used for farming. After cultivation, the area is left alone for several years so as to allow its recovery. The farmers then move on to other areas and repeat this process.
Detailed explanation-3: -The vegetation is typically cleared by fire, and the ashes contribute to the soil’s fertility by adding potash (fertilizer).
