Abstract
The effect of different combinations of what straw with (NH4NO3)-N-15- N-15 having a wide range of C:N ratio-2.5 to 108, on the dynamics of m obilization-immobilization of fertilizer nitrogen, as well as on its l osses and utilization by plants has been studied in a vegetation exper iment on gray forest soils. The importance of the phytomass carbon for stabilizing the soil nitrogen cycle is shown. Correlations between im mobilization processes of N-15 of fertilizer and mobilization of soil N-14 are discussed.
