. Most of the drugs and pharmaceuticals are also organic compounds. In agriculture too, organic chemistry is well represented. Fertilizers like urea, pesticides like DDT, malathion and gammaxene, and plant growth regulators are all organic chemicals. Among va..

Soil's fertility is its capacity to sustain plant life with required nutrients. Fertility of soil decreases when the same crop is grown in the same land repeatedly, or by soil erosion. Erosion is the physical removal of soil particles from their original places and transporta..
