Effect of multi-purpose compost and Azotovit preparation on content of separate microorganism groups

In the article the influence of highly technological organic fertilizer of the multi-purpose compost (MPC) and the biologic preparation on the basis of Azotovit on the content of separate microorganism groups in the model experiment on sod-podzolic soil is considered. The MPC is the basic development of the All-Russian Research Institute of Reclaimed Lands, which was awarded the State premium of the Russian Federation, it is implemented in the Russian Federation and the near abroad. Azotovit is included in the modern list of pesticides and agrochemicals, has a complex effect, enriching the soil with nitrogen, simultaneously synthesizes vitamins, auxins, antibiotics that suppress the growth of pathogens. The investigations were carried out with the purpose of revealing the joint prolonging action of the MPC with potato tubers treated with Azotovit into separate groups of microorganisms. In the experiment, Red Scarlet potatoes were used. The analysis of the quantitative part of different groups of microorganisms showed their growth on the variant with the introduction of organic substrate - multi-purpose compost and tubers of potatoes treated with nitrogen fertilizer (MPC + tubers with Azotovit). For all the groups represented, this variant is distinguished both in dynamics and in the average for growing potatoes. The high activity of soil biota is also due to the presence of a sufficient number of amylolytic microorganisms. The largest part was observed as in the case of ammonifying microorganisms on the MPC + version of tubers treated with Azotovit and amounted to 17.4 million/g for the first selection (May) to 29.4 million/g for harvesting (August). The application method of decomposition of linen cloth indicates that the treatment of potato tubers with the bacterial preparation Azotovit on the background of the multi-purpose compost (the first year of aftereffect) increases the activity of cellulose-decomposing microorganisms, making up 73% of the decomposition of the linen cloth against 65% in the variant with MPC and 41% in the control option without fertilizer.
