Mineral fertilizers role in nitrogen biological activity increase on grain rhizocenosis under the Caucasus conditions

The natural–geographic, soil–climatic conditions of Ganja–Qazakh massive in the Lesser Caucasus are characterized in the article, the experimental results of the mineral fertilizers various doses, impact on microorganism’s development in wheat and maize wheat are examined. In the course of the research, it was established that the fertilizer system has a significant effect on the nitrogenase activity of the rhizosphere bacteria. The amplitude of the oscillation is different for individual crops. As is customary, the amount of nitrogenase activity is variable in relation to the plant physiology itself, which reaches its maximum values with the active growth of crops, especially during the period of winter wheat and cornflower. The biological potential of the soil is inversely proportional to the anthropogenic load. From which it should be concluded that an increase in the mass of agrochemicals reduces the possibility of natural resources, like the molecular nitrogen of the atmosphere
