Organic farming in India

 Organic farming avoids chemical pesticides and fertilizers and seeks to increase soil fertility through feeding soil micro-life with residues from life such as garbage compost and sewage, manure, plant residues, food processing wastes etc. Organic farming rely on biological processes to obtain high quality and yields which are as good as these achieved using modern techniques as agricultural production.

Organic manure involves blending the carbon, nitrogen, phosphorus, potash rich materials, in which the trace elements are present in proportion and the crucial carbon- nitrogen ratio (C/N) is neither too high nor too low. This kind of preparation is within the competence of farmers. There is no need of adding some nitrogenous fertilizer as supplement. The chemical nitrogenous fertilizer upsets the nutrient balance of soil. Nitrogenous fertilizer is known as stimulant of growth and there is craze for it among the farmers.

Nature has made ample provisions for the supply of nitrogen through the variety of ways. Bacteria in the nodules of leguminous plants capture nitrogen from the atmosphere and fix it into the soil. Various genera have been endowed with nitrogen fixing quality so that this operation could continue under different conditions. So do some ferns (azolla), blue green algae and some genera of free living bacteria (azatobacter, Clostridium).
