♤ In this practice a patch of land is cleared, vegetation is burned and the ash is mixed with the soil thus adding nutrients to the soil.
♤ This patch of land is used for raising crops for two to three years, and the yield is modest.
♤ Then this area is abandoned and is left to recover its fertility, and the same practice is repeated elsewhere on a fresh piece of land.
♤ All that is required for this method of cultivation is a set of simple tools, not high level of mechanisation.
