The effect of organic fertilizers (cattle manure and lupine green manure), as well asmicrobial preparation Biohran on the dynamics of the activity process of nitrogen fixation andN2O emissions in the rhizosphere soil of potato plants, crop yield, and product quality have beeninvestigated. The use of manures stimulates activity of nitrogen fixation, but at the same time,accompanied by a significant loss of gaseous nitrogen compounds. The efficiency of Biohran bythis agrobackground is largely levelled. Lupine green manure stimulates nitrogenase activity,especially in combination with biopreparation. At the same time, there is a tendency to reducenitrous oxide emission. Organic fertilizers contributed to a reliable raise of potato yield. Biohranprovide productivity gains only on the background of green manure. Microbial preparationcontributed to the improvement of quality of production parameters by all studiedagrobackgrounds.
