Fate and management of fertilizer nitrogen in agro-ecosystems,987 (ISFCAAS 1986; ECACA 1988), accounting for 19% of the total world consumption in 1986/1987 (FAO 1987). It was forecast that in the year 2000 fertilizer N consumption in China will be further increased to 18 million t (ISFCAAS 1986; Lu 1979). Therefore, the efficient use of fertilizer N is more i

Nitrification,tion is inter-linked with the mineralization-immobilization and N loss processes, it is an important N transformation which is related not only to the efficiency of fertilizer N, but also to the contamination of the environment. In this chapter some aspects of nitrification relating to investigations in China will be discussed.
