chemistry assignment on contribution of chemistry in the field of agriculture

Significant contributions towards securing enough food grains and protecting crops have been made by the use of chemistry. These are: Chemical fertilizers like urea, ammonium sulphate, calcium nitrate etc., for the better production of crops. Insecticides such as DDT, BHC,..

Nuclear reactions, such as nuclear fission, nuclear fusion, transmutation processes etc. are studied under this branch. In addition, with new developments emerging in recent years, more branches of chemistry are being added. These include, pharmaceutical chemistry, geochemistry..

Soil Erosion occurs when the weathered soil particles are dislodged and carried away by wind or water. Deforestation, agricultural development, temperature extremes, precipitation including acid rain, and human activities contribute to this erosion. Humans speed up this process..

The electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate in regular,..

B ), which is equal to 9.27 x 10 - 2 4 Am 2 . For each electron in an atom, the spin magnetic moment is..

Biotechnology is science of manufacturing useful substances, chemicals, medicines by use of living organisms and their life process. In fact, biotechnology is not a new science. Alcohol was the first product manufactured by ancient biotechnologist. In recent years, biotechnology is growing as a sep..
