Sapropel is a sludge-like natural organic substance formed by deposits on the bottom of freshwater bodies of dying plants and microorganisms with limited access of oxygen. Sapropel raw materials — highly efficient organic organo-mineral fertilizer, representing the deposition of freshwater bodies of water, containing biochemically valuable microelements and microorganisms of various physiological groups. Sapropel contains all the nutrients necessary for growth. and plant development.
Formed by natural physicochemical processes occurring in the reservoir over tens of thousands of years, the composition of sapropel determines its qualitative and agronomical evaluation of the raw materials used by mankind in as fertilizers, aeliorants (recultivators), soil formers.
