What is slash and burn agriculture? …

Slash and burn is  a method of agriculture used in the tropics, in which forest vegetation is felled and burned, the land is cropped for a few years, then the forest is allowed to reinvade.
Salient features of slash and bum agriculture are as follows:

1. Slash and burn agriculture is most often practised in places where open land for farming is not readily available because of dense vegetation.
2. This type of farming is carried out by tribal communities in India.
3. A patch of land is cleared and burned for cultivation for a few years.
4. Digging stick is mainly used for cultivation.
5. Cultivation largely depends on monsoon rains for irrigation and natural fertility of the soil.
6. They grow only sedentary crops like cereals and other crops for their bare sustenance.
7. Land productivity is quite low as farmers do not use fertiliser and other modern inputs.
