摘　　要：探讨了农田氮肥损失的途径及其对环境造成的危害 。Foodstuff increase with increasing nitrogen fertilizer applied in agriculture. But,unreasonable applying nitrogen fertilizer will cause some kickback such as polluting rivers and lake,polluting groundwater,polluting atmosphere,increasing NO 3 - content of drinking water and plant,accordingly be harmful to health of people.Loss of nitrogen fertilizers in agriculture mainly includes several routes:nitrification loss,denitrification loss,ammonia volatilization loss,leaching loss and loss from erosion.Study on route and mechanism of nitrogen fertilizer loss will benefit to apply nitrogen fertilizer reasonably, to avoid wasting nitrogen fertilizer,to improve nitrogen fertilizer efficiency and to reduce nitrogen fertilizer pollution.This paper discusses the loss routes of nitrogen fertilizer from agriculture.its harmfulness to environment and countermeasure.\;
