If you are a farmer, it makes sense to insure your crop. Let me explain.
You planted rice, you are expecting a good harvest. However, unfortunately, it rains hailstone and your crop is destroyed. While hailstone is a natural phenomenon, so there is no way you can stop or predict hailstone, you can insure your crop and recover from financial loss.
In order to insure your crop, you will have to first apply to the insurance company that provides crop insurance (not all insurance companies have this offer). Someone from the company will come to your farm and assess the potential value of your crop. You then pay the premium and insure your crop. If there is no damage to your crop, the insurance company keeps your premium, but in case the crop is destroyed, the company will provide financial assistance as agreed on the policy document.
