FIELD: ecology, agriculture. ^ SUBSTANCE: invention relates to soil ecology, namely, to producing agents based on natural components used for elimination of technogenic pollutions of soils. The biopreparation based on humus substances is prepared by mixing and milling turf, avian dung and alkali with addition of water in disintegrating device. Turf, avian dung, alkali and water are taken in the ratio, mas. p. p. = (15-20):(11-16):(0.3-0.6):(0.3-0.6), respectively. Mixing and milling all components in disintegrating device can be carried out with addition of wood saw-dust taken in the amount 3 mas. p. p. per 1 mas. p. of mixture of other components. The biopreparation elicits the strongest reductive function with respect to heavy metal oxides and can be used for improvement of soil ecology after technogenic emergency and for prophylaxis aims for neutralization of oxides and enhancing the humus content in soils. Invention can be used in carrying out measures for reducing pollution degree and toxicity in forest, agricultural and other soils with recovery of biota. ^ EFFECT: valuable properties of biopreparation. ^ 2 cl, 3 ex |
