Fertilizers

It is very difficult to meet the demands of the increasing population with fewer resources. Loss of soil fertility, pests, and lack of nutrients has resulted in decreased agricultural production. This has increased the importance of fertilizers in agriculture. A fertilizer is any material of natural or synthetic origin that is applied to soils or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Without the addition of fertilizers, agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops. Thus, in order to meet human nutritional needs in the crops we eat, we need to replace what we take out. The key is to get this balance right and to maintain a level of nutrients in soils that will support our crops without applying excess. Fertilizers can be divided into two groups viz., Mineral fertilizers (phosphorus and potash) which are mined from the environment and crushed or chemically treated before being applied and Industrial fertilizers (ammonium phosphate, urea, ammonium nitrate) which are produced industrially by humans through chemical reactions. Fertilizers are essential to the security of the world’s food supply, and they must be used properly. The manufacture, sale and transportation of fertilizers is heavily regulated. States have difference regulations and statutes that address fertilizer use and production to protect human health and the environment. Fertilization is a central component of farming that impacts both crop productivity and the quality of the environment. The goal is to ensure there are sufficient levels of nutrients based on crop requirements, peak harvest times, and the soil’s natural ability to provide nutrients. Since proper fertilization means achieving a dynamic balance, any imbalance can lead to economic losses and the contamination of groundwater and surface water. The risks are even greater when the soil’s health is affected. Therefore, fertilizer recommendations have to made based on native soil available nutrients
