The Brainliest Answer!
Buffer stock is the stock of foodgrains , namely wheat and rice procured by the government through food corporation of india (FCI). The FCI purchases wheat and rice from the farmERS in the state where there is a surplus production. The purchased foodgrains are stored in grainaries . This is done to distribute foodgrains in the deficit areas and among the poorer strata of the society at a price lower than market price , also known as Issue price . This helps in resolving the problem of the of shortage of food
