Distinguish between plantation and shifting agriculture.

Shifting agriculture: it is the process of agriculture in which a small area of a forest is cleared by cutting down all the trees and the area is banned.the ashes are mixed with the soil to make it more fertile for the crops to grow.when the land becomes less fertile it is abandoned.this practice is known as slash and burn agriculture.these regions are generally with heavy rainfall plantation agriculture:in this cultivation vast lands are brought under a single crop.large amounts of chep but skilled labour,scientific technique,transport network and marketing skills are employed.the farm produced are either processed in their factories or are sold as raw material to other industries.some of the farm produce is exported too
