The invention relates to chemical methods for the preparation of biologically active mixtures, intensifying the growth and improving the quality of plants, and can be used in agriculture. The method for the preparation of biologically active mixture is proposed by mixing of calcium-carbonate raw material with phosphate acid, besides phosphate acid in composition of initial mixture is taken in quantity of 7.15-36.20 weight %, and as calcium-carbonate raw material defecation mud of sugar production is used. |
