Agriculture fertilizer is a type of substance that is used to enhance the fertility and productivity of soil for crop production. It provides essential nutrients to plants, such as nitrogen, phosphorus, and potassium, as well as micronutrients such as calcium, magnesium, and sulfur, that are necessary for healthy plant growth.There are several different types of agriculture fertilizers available, including organic and inorganic varieties. Inorganic fertilizers are typically made from chemicals, whereas organic fertilizers are made from natural sources, such as animal manure, compost, and plant-based materials.Agriculture fertilizers can be applied to crops in various ways, including broadcasting, drilling, and foliar application. They can also be applied at different stages of the plant's growth cycle, depending on the specific nutrient requirements of the crop.
