Fertilizer

Summary: When plants grow, they remove minerals from the soil. These would normally be replaced when the plant dies, or when leaves drop off. However, when crops are cut and gathered, this cannot happen. To prevent future crops suffering from a mineral deficiency, farmers add chemicals to the soil to replace missing minerals – these chemicals are called fertilizers.
