Abstract

The research on soil nitrogen dynamics of crop structures of the feed system studied had se purpose to reveal the amounts of Nt  made at the end of  the vegetation periods and on the entire cumulative period of each system, both in unfertilized and fertilized variants with nitrogen. Following the obtained results there was found that the introduction into the feed of corn silage and aristed ryegrass the cumulative amount of Nt in soil was 181.5 kg / ha, at the unfertilized variants and 190.2 kg/ha in the nitrogen fertilized variants.
