Abstract:

Foodstuff increase w ith increasing nitrogen fertilizer applied in ag riculture.But, unreasonable applying ni trogen fertilizer will cause some kickback such as polluting rivers and lake, polluting g roundw ater, polluting atmosphere, increasing NO3- content of drinking w ater and plant, accordingly be harmful to health of people.Loss of nitrogen fertilizers in ag riculture mainly includes several routes : nit rification loss, denit rification loss, ammonia volatilization loss, leaching loss and loss f rom erosion. S tudy on route and mechanism of nit rogen fertilizer loss w ill benefit to apply nitrogen fertilizer reasonably, to avoid wasting nit rogen fertilizer, to improve nit rogen fertilizer ef ficiency and toreduce nitrogen fertilizer pollution.This paper discusses the loss routes of nit rogen fertilizer from agriculture.its harmfulness to environment and countermeasure.

Key words: nit rogen fert ilizer loss, farmland, environmental pollution, countermeasure
