Reducing Usage Of Chemicals

Various chemicals such as pesticides, insecticides and fungicides play important roles in plant growth; however the overuse of these chemicals is considered to be one of the prime factors leading to soil pollution. Reducing or even avoiding the use of such chemicals is one of the most elementary and important preventive measures. Manures and bio-fertilization can be used as alternatives to chemicals. Manures are often recommended by environmentalists and agriculturists because, as compared to pesticides, manures have minimal adverse effect on the environment. Bio-fertilization is a process in which certain microorganisms such as rhizobium are used to increase the soil fertility in place of chemicals.
