The article deals with the results of environmental regulation of doses introduced into a multicomponent carbon-containing preparation for the burning of heavy metals and the microbiological activity of the soil. The relevance of the research is based on, on the one hand, in global degradation, degasification and reduction of soil fertility. On the other hand, it is the worldwide accumulation of production and consumption waste. This study aimed to assess the effect of doses of the product from ash, slag, and carbon black on pH, heavy metal content, and microbiological activity of ordinary chernozem soil for cultivating spring wheat. The experiments were conducted in a walled-zone of Northern Kazakhstan. Soil pH was determined by a potentiometric method, the application of floe discovered the microbiological activity of the soil, the microflora was accounted for by sowing the soil suspension on solid nutrient media, and heavy metals were determined by stripping voltammetry. Bacteria utilizing organic nitrogen compounds; microorganisms consuming mineral nitrogen; oligonitrophils; bacteria mobilizing mineral phosphates; cellulose-destroying microorganisms; nitrification and mushrooms were studied. The studied preparation was observed to contribute to the neutralization of the soil, and the activation of microbiological processes. According to the evidence, it can be verified that the preparation of ash and carbon black ambiguously affects the number of microorganisms. An increase in the number of ammonifying bacteria, nitrifying agents and the coefficient of transformation of organic matter, as well as an increase in the availability of soil with easily hydrolyzed nitrogen, were noted. The content of heavy metals did not exceed the maximum permissible concentration. Thus, the use of a product based on ash, slag, and carbon black to fertilize black earth soils on spring wheat crops are environmentally safe.
