Agricultural Chemistry: A look into the mechanics of fertalizers, pesticides and human influence on growing crops

Agricultural Chemistry

Modern agriculture depends quite heavily on the advances that have been make in science and chemistry in particular, to maximize the make of crops and animal products. Fertilizers, pesticides, and antibiotics play ever increasing roles in this field.

Fertilizers atomic number 18 perhaps the most widely roled form of chemic in agriculture. Fertilizers be added to the soil in which crops are increase to set aside nutrients required by the plants. Fertilizers can be divide into two categories: natural and inorganic. Organic fertilizers are derived from living systems and overwhelm animal manure, guano (bird or bat excrement), fish and bone meal, and compost. These organic fertilizers are decomposed by microorganisms in the soil to release their nutrients. These nutrients are then taken up by the plants. Inorganic or chemical fertilizers are less chemically complex and usually more highly concentrated. They can be formulated to provide the correct balance of nutrients for the specific crop that is being grown. both(prenominal) organic and inorganic fertilizers supply the nutrients required for maximum developing of the crop. Inorganic fertilizers contain higher concentrations of chemicals that may be in short supply in the soil. The major or macro- nutrients in inorganic fertilizers are nitrogen, phosphorous, and potassium. These fertilizers also may provide new(prenominal) nutrients in much smaller quantities (micro-nutrients).

With the expansion of cities due to increases in population, there has been a sacking of agricultural land. Appropriate use of fertilizers to increase crop has in part counterbalanced this loss of land. The use of fertilizers is not without its faults, however. There are concerns that adding supplements of nitrogen, particularly in the form of inorganic fertilizers, can be detrimental. It is thought that adding surplus nitrogen to the soil can disrupt the action of nitrogen-fixing bacteria, an consequential part of the nitrogen cycle. If these...
