Biologically Active Substances from Oxidized Lignite of the Itatsky Deposit

Abstract

Abstract Biologically active substances of natural origin are of great interest for agriculture, as their use allows to increase the efficiency of the industry and to obtain environmentally friendly products. The purpose of this work is to determine the biological activity of potassium humates obtained from oxidized brown coal beds of the Itatskoe deposit in the Kansko-Achinsky brown coal basin. Alkaline extraction of potassium humates and study of their biological activity were carried out in l…
