The results of studies of environmental safety of a new organomineral fertilizer based on highly concentrated pig farm waste are presented. The effect of the fertilizer on spring wheat yield was evaluated. The vegetation experiment was carried out on spring wheat Zlata under phytotron conditions on sod-podzolic loamy soils. The effect of the organic mineral fertilizer, granulated bird manure and mineral fertilizers (NPK) in equivalent doses on toxicity and efficiency of biomass growth is compared. Based on the experimental data, the optimal dose of the new fertilizer was determined and the uselessness of higher doses was substantiated. The agro-reclamation value of the fertilizer produced by processing the reagent of liquid pig farm waste was substantiated. The effect of the fertilizer on the soil microorganisms was evaluated. For the diagnosis of group and partial species composition of soil microorganisms, the method of sowing on agar plates was used. The results of changes in the number of ecological groups of soil microorganisms are presented. It was found that organic fertilizer is not toxic and improves soil fertility.
