Any type of material that increases soil yield, both qualitatively and quantitatively, to strengthen the soil and increase its fertility is called fertilizer. The current study examines the production of a new effective fertilizer. Results presented involve effects of new bioorganic-mineral compositions obtained from the combination of vermicompost and sulphur-containing waste from sulphuric acid production on the yield and quality of tubers (beets, carrots). An increase in the yield of tubers has been found to be 1.13–1.25 times when the bioorganic-mineral composition (~20 Mg∙ha–1) is introduced into the sierozem (serozem) soil. The best results are obtained with mass ratios in the range 30–45 and 55–70 for vermicompost and sulphur-perlite-containing waste, respectively. The effectiveness of the mixture of vermicompost and sulphur-containing waste is explained by the increased synergistic interaction of these components. The proposed composition has high structure-form-ing, water-retaining, nutritional and biologically active properties.
