How is ‘jhooming’ carried out?

Jhooming agriculture is also known as 'shifting' or 'Slash and burn' agriculture. This type of agriculture is mostly practised in North-East India. In Jhooming agriculture, a patch of forest land is cleared by burning and crops are grown. After 2-3 years, when the fertility of soil is exhausted, the land is abandoned. The farmers then clear another piece of land and process continues. After 10-15 years the farmer may return to the first piece of land.
