Buffer Stock - It is the stock of food grains, particularly wheat and rice, which the government procures through the Food Corporation of India (FCI). The FCI purchases these cereals directly from the farmers of those states where they are in surplus. The price of these commodities is much before the actual sowing season of these crops. The food grains thus purchased by the FCI are kept in big granaries and are called Buffer Stock. Maintaining buffer stock is a step taken by the government in order to ensure food security in the country.
