TECHNOLOGY FOR THE PRODUCTION OF GROWTH STIMULANTS BASED ON GREASY WASTEWATER FROM WOODWORKING ENTERPRISES

The paper considers the applicability of an innovative technology for the production and use of growth stimulants for various crops based on aqueous extraction of a bark-containing mass formed during wood processing in the form of wastewater. This solution will improve the environmental efficiency of enterprises in the woodworking industry by expanding the range of products that can be used in related industries, including the agro-industrial complex. The paper presents studies on the testing of extractive substances of a bark-containing mass with a special method of its preparation as a growth stimulator for a number of test crops, including those used for the reclamation of territories. It has been established that specially prepared aqueous extracts have pronounced growth–stimulating effects in relation to the selected seed material (a significant increase in root length by 35-40%, and sprouts by more than 42-44%) and can be recommended for use as growth stimulants in the preparation of seed for horticulture.
