描述The study of soil nitrogen has long been an active field, but it was generally pivoted on agricultural and forestry production, and animal husbandry. With the rapid increase in the use of fertilizer nitrogen, more attention has been paid to the rela­ tionship between nitrogen management and environmental quality and human of soil nitrogen has become more comprehensive with health. In addition, the study the development of related sciences. The quantitative study of the processes in nitrogen cycling and their interrelationships has been an important part of this project and has attracted the attention of scientists allover the world. Nitrogen is one of the most important nutrients for plant growth and the applica­ tion of fertilizer nitrogen is playing an important role in agricultural production. The annual consumption of fertilizer nitrogen in the world has reached 70 million tons, and China has an annual consumption of more than 15 million tons and is the largest fertilizer nitrogen consumer in the world. However, the efficiency of nitro­ gen fertilizer is low and losses are large. It is estimated that nitrogen losses from agriculture in our country can be as high as 40-60% of th

Transformation and management of manure nitrogen,tilizer industry, consumption of fertilizers has been raised dramatically, while the relative contribution of organic manure to the total input of nutrients, especially N, has declined continuously. Nevertheless, the absolute amount of nutrients applied as organic manure has increased significantly.

Forms and amount of nitrogen in soil, of N in soil is essential for understanding the N supply characteristics of a soil and for the efficient management of fertilizer N. In this chapter, a brief account of the forms, distribution and amounts of N in the soils of China is presented.

Fixation and release of ammonium,son 1959; Stevenson and Dhariwal 1959). Fixed ammonium may account for as much as 50% of the total N in the top metre of some soils, and the fixation and release of ammonium plays a prominent role in the internal cycle of N in soils.

Nitrogen management and environmental and crop quality, Dalian, reviewing the progress in the related research fields in China (EBESIN 1983). This chapter will discuss the problems for environmental quality caused by N loss from fertilizer applications to field crops, their counter measures, and the interrelationships between field N management, crop quality and animal health.

Denitrification,ion so that the terminal product is N2 rather than gaseous N oxides (Picard and Faup 1980; Roger .. 1976). In this way, it is possible to prevent the water body from being polluted by nitrate and ensure that the atmosphere is not contaminated with gaseous N oxides.

Ammonia volatilization,s negligible (Denmead .. 1977), but it was as high as 47% of the applied N when the fertilizer was applied to the floodwater after transplanting rice, when the weather was sunny and the winds were strong (Fillery .. 1984).

Biological nitrogen fixation,ural production throughout the world. Dou (1989a) estimates that N input through BNF was greater than fertilizer N input in Australia, New Zealand and USA. In China, N input through BNF in 1987, though much less than fertilizer input, still amounted to 14.5% of the total input in agriculture (Table 14.9).
