HORTICULTURE

Detailed explanation-1: -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-2: -Slash-and-burn is a type of shifting cultivation, an agricultural system in which farmers routinely move from one cultivable area to another. A rough estimate is that 200 million to 500 million people worldwide use slash-and-burn. Slash-and-burn causes temporary deforestation.

Detailed explanation-3: -Slash-and-burn agriculture is often used by tropical-forest root-crop farmers in various parts of the world, for animal grazing in South and Central America, and by dry-rice cultivators in the forested hill country of Southeast Asia. The ash provides some fertilization, and the plot is relatively free of weeds.
