Centre for Science backed magazine Down to Earth in a 10-year long study named Indian Nitrogen Assessment reports the excessive use of nitrogenous fertilizers implicit in nitrogen pollution of soil and water resources.
They reported that an average farmer used about 6000 Kg of Urea in past five decades. Only 33% of the nitrogen is transferred to the plant and 67% enters our soil and groundwater.
Poor soil quality, high nitrate presence in groundwater and declining soil chemistry are the resultant effects.
Excessive uptake of nitrogen is harmful in children while formation of Nitrous Oxide a more potent greenhouse gas than Carbon dioxide is another big issue.
