What is slash and burn practice?

Answer: Slash and Burn is a way of cultivating land where farmers clear a piece of land by slashing or cutting down trees and bushes. These are then burnt, which releases the nutrients into the soil. Now crops are grown in this cleared field for a few years. After repeatedly using the patch of land, the soil looses its nutrients. So it is abandoned. Then they clear another plot of land to plant. In the meantime young trees grow in the old field. In this way soil fertility is restored. People can then return to it and start cultivating it again.
