Agricultural chemistry

Agricultural chemistry deals with the substances and chemical reactions that are involved with the production, protection and use of crops and livestock. Agricultural chemists develop fertilizers, insecticides and herbicides necessary for large-scale crop production. They must also monitor how these products are used and their impacts on the environment as many of these products can have a strong negative impact on the surrounding environment causing much damage if not used correctly. As for livestock, nutritional supplements are developed to increase the productivity of meat and dairy herds which lead to more fertile and faster bigger growth of livestock. Agricultural biotechnology is a very important topic for many agricultural chemists. Genetically manipulating crops to be resistant to herbicides used to control weeds in the fields requires detailed understanding of both the plants and the chemicals at the molecular level. Biochemists must understand genetics and chemistry to help develop crops that are easier to transport or that have a longer shelf life therefore increasing profits for businesses.
