By 2009-10 total fertilizers consumption in the country was 26.49 million nutrient tones.

Arable soils leak considerable amounts of nitrate, phosphate, potassium and other nutrients mainly through run-off and erosion, which enrich the water body in terms of nutrients leading to luxurious growth of algae and other organisms and resultant eutrophication problems in ponds Ammonia Volatilization Volatilization of NH3 is not only a major loss of N but also a cause of environmental pollution. From the atmosphere NH3, is washed out by clouds and redeposit' on the terrestrial ecosystem In the atmosphere it is oxidized to N2O, which acts as a greenhouse gas and is responsible for the destruction of ozone layer. It also forms salts with acidic gases and these salt particles can be transported long distances especially in the absence of clouds. The deposition close to the source is substantial, but hard to estimate due to interaction with other pollutants. Acid
