Subclasses of this are herbicides, insecticides, fungicides, rodenticides, pediculicides, and biocides depending on its target. With active research in this field safer and greener pesticides are being developed. Insecticides are chemicals that are used to kill insect because they can spread livestock diseases, can eat stored grain, and can feed on growing crops.

However not all insects are harmful, and certain species of insects are needed to pollinate plants to ensure that they set seed. These chemicals prevent crop losses to insects and other pests. Another study. Plastic pipes for improved irrigation : Plastic was derived from chemistry and this is widely used in agriculture. This has increased irrigation massively which results in a better environment for the crops to prosper in.

Storage and preservation of agriculture produce: Sulfur dioxide is used to keep grain fresh and useable for a longer period of time. Food preservatives like sodium benzoate and salicylic acid are used for longer shelf life. New generation refrigerants have been developed.

Chemicals are added to promote the ripening of fruits or the germination of seeds. Food packaging has advanced due to the material produced by advancements in chemistry.

Chemistry in other areas of agriculture: Plastic pipes for improved irrigation : Plastic was derived from chemistry and this is widely used in agriculture. Production of alcohol from bagasse which is used as the feedstock for chemicals is good example, Conclusion: Thus Chemistry has been and is still closely linked to the progress in agriculture field.

The goals of agricultural chemistry are to expand understanding of the causes and effects of biochemical reactions related to plant and animal growth, to reveal opportunities for controlling those reactions, and to develop chemical products that will provide the desired assistance or control. Every scientific discipline that contributes to agricultural progress depends in some way on chemistry.

Hence agricultural chemistry is not a distinct discipline, but a common thread that ties together genetics , physiology , microbiology , entomology , and numerous other sciences that impinge on agriculture. Chemical materials developed to assist in the production of food, feed, and fiber include scores of herbicides , insecticides , fungicides , and other pesticides , plant growth regulators, fertilizers , and animal feed supplements.

Chief among these groups from the commercial point of view are manufactured fertilizers, synthetic pesticides including herbicides , and supplements for feeds. The latter include both nutritional supplements for example, mineral nutrients and medicinal compounds for the prevention or control of disease. Agricultural chemistry often aims at preserving or increasing the fertility of soil , maintaining or improving the agricultural yield , and improving the quality of the crop.

When agriculture is considered with ecology , the sustainablility of an operation is considered. Modern agrochemical industry has gained a reputation for its maximising profits while violating sustainable and ecologically viable agricultural principles. Eutrophication , the prevalence of genetically modified crops and the increasing concentration of chemicals in the food chain e. From Wikipedia, the free encyclopedia. Branches of chemistry.

As mentioned earlier, there are broadly two categories of fertilizers namely, organic and inorganic. The organic fertilizers are naturally derived from the animal manure, compost or the fish and bone meal. Through decomposition by the microorganisms which are found in the soil, these fertilizers release nutrients which are essential for crop growth.

Unlike organic fertilizers, inorganic fertilizers are synthesized through the Haber-Bosch process. In this process, ammonia is produced as the end product which is used in combination with other nitrogen fertilizers. Chemistry has been successful in the production of pesticides which have minimized the crop damage by pesticides. Depending on the targeted pest, pesticides include fungicides, pediculicides, herbicides, biocides, and insecticides. Through the development of vitamins, minerals, sweeteners, and saccharin, consumers have benefited from chemistry regarding appearance, nutritional value, availability, and flavors of their food.

Chemistry is linked to the progression of agriculture. It has helped produce innovative ways which have to broaden the boundaries of agriculture hence increase the production. However, as a chemistry student, understanding how all these chemistry concepts work can be not only complex and tiresome but also time-consuming.

So, how can we classify the role of chemistry in agriculture? Fertilizers Fertilizers are merely materials that are added to the soil to supply one or more nutrients needed for the growth of plants. Pesticides Chemistry has been successful in the production of pesticides which have minimized the crop damage by pesticides.

Food processing Through the development of vitamins, minerals, sweeteners, and saccharin, consumers have benefited from chemistry regarding appearance, nutritional value, availability, and flavors of their food. Need help with your chemistry homework? It plays a role from the basics of photosynthesis to the utilization of agricultural produce. The advancements in this practice is only because of active research carried out in chemistry and then its applications to cause the land to produce more abundantly and at the same time to protect it from deterioration and misuse.

Role of Chemistry in agriculture can be classified as follows:. Photosynthesis: This natural process provides the basic building block for all the agricultural products. The overall process is best shown by the net equation.

No chemical process is more important to life on Earth than photosynthesis. Without photosynthesis, not only would there be no plants, the planet could not sustain life of any kind. Research in this area has led to understanding the mechanism and hence to optimize conditions for maximization of this process.

Fertilizers: Fertilizer is any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants. Fertilizers can be divided into two categories: organic and inorganic. Organic fertilizers are derived from living systems and include animal manure,fish and bone meal, and compost. These organic fertilizers are decomposed by microorganisms in the soil to release their nutrients for use by plants.

Chemical fertilizers are less complex and have high concentrations of chemicals that may be in short supply in the soil namely nitrogen, phosphorous, potassium, calcium, magnesium and sulfur. Fertilizers also provide micro nutrients which are required in much smaller quantities namely boron, chlorice, copper, iron, manganese, molybdenum and zinc. Inorganic fertilizer is synthesized using the Haber-Bosch process, which produces ammonia as the end product.

This ammonia is used for other nitrogen fertilizers, such as anhydrous ammonium nitrate and urea. Now fertilizers with slow release of nutrients have been developed. Appropriate use of fertilizers to increase crop yield has counterbalanced loss of land due to urbanization and significantly supported global population growth, It has been estimated that almost half the people on the Earth are currently fed as a result of synthetic nitrogen fertilizer use. Pesticides and Insecticides: In order to minimize the damage of the crops by pests a large variety of chemicals known as pesticides are used.

Subclasses of this are herbicides, insecticides, fungicides, rodenticides, pediculicides, and biocides depending on its target. With active research in this field safer and greener pesticides are being developed. Insecticides are chemicals that are used to kill insect because they can spread livestock diseases, can eat stored grain, and can feed on growing crops. However not all insects are harmful, and certain species of insects are needed to pollinate plants to ensure that they set seed.
