| Abstract: | A summary is presented of progresses that have been achieved since the 1930s in the research on soil nitrogen(N) in China,covering 1) nature of soil N and soil N fertility,2) N in organic manure,3) the fate and yield-increasing effect of chemical fertilizer-N applied to agricultural fields,4) impacts on the environment of the losses of chemical fertilizer-N applied to agricultural fields,and 5) N balance in the agricultural ecosystem.It is obvious that the research benefits much from the progresses made in ... |
