Agriciltural microbiology| Резюме: | The paper depicts the study of mineral nitrogen and pre-sowing seeds bacteryzation on the development of nitrogen fixing bacteria and the activity of autotrophic and heterotrophic nitrification. It was revealed that nitrification activity in the root zone of winter rye plants rises together with the increase of mineral nitrogen doses. Heterotrophic nitrification plays a significant role in the formation of nitrate pool in the root zone, especially during the early stages of plants organogenesis. Application of the microbial preparation Diazobakteryn had enhanced the activity autotrophic and heterotrophic nitrification processes in the rhizosphere soil of plants in the spring, during the early stages of their development while during the next organogenesis phases the reduction of nitrification processes was observed. In plants-free soil the contribution of heterotrophic nitrification to biological transformation of nitrogen was negligible. |
