FIELD: agriculture, fertilizers. ^ SUBSTANCE: invention relates to humic acids-containing sapropel concentrate prepared by treatment of wetted sapropel with alkaline agent that comprises product after treatment of wetted sapropel with ash as sapropel concentrate by ultrasonic treatment. Product after treatment of wetted sapropel comprises 2.7 g/l of humic acids, not, less at pH 9.8-12.5. Invention proposes a method for preparing sapropel concentrate comprising humic acids by treatment of wetted sapropel with alkaline agent wherein ash is used as the latter. Treatment is carried out by ultrasonic effect in the ratio 2-10 mass. p. p. of ash per 100 mass. p. p. of wetted sapropel. Invention provides expanding fields in applying sapropel concentrate and to simplify a method for it preparing. Invention can be used in manufacturing organomineral fertilizers, biological supplements used in producing cosmetic articles, medicinal preparations and other pharmaceutical agents. ^ EFFECT: improved preparing method. ^ 5 cl, 1 tbl, 12 ex |
