The stock of foodgrains acquired through the Food Corporation of India (FCI) by the Government is known as buffer stock. Mainly rice and wheat are procured.
Granaries are used to store the food grains that are purchased.
Government uses this buffer stock to distribute the food grains to poorer sections of the society at lower than the market price which is also known as the issue price.
Buffer stocks help in solving the problem of food shortage during calamity and when weather conditions are adverse.
To give incentives to the farmers to raise crop production, the Government declares the Minimum Support Price (MSP) before the beginning of the sowing season.
When the FCI purchases the foodgrains from the farmers with surplus production, they are paid a pre announced price.
Minimum Support Price (MSP) is the term used to describe the pre announced price that is paid to the farmers.
