Use of peat and sapropel for obtaining humic plant growth regulator

The selection of peat and sapropel raw materials for obtaining a humic plant growth regulator with increased biological activity is experimentally substantiated. The use of peat and sapropel as raw materials for hydrolysis and the production of biologically active preparations makes it possible to transfer a significant amount of microelements into solution. In Lelchitsky district of Gomel region, the raw material bases of peat and sapropel, suitable for obtaining biologically active preparations, have been identified and characterized. The choice of the priority site Pribylovichi with deposits of low-lying sedge and sedge-reed peat and siliceous sapropel is substantiated. Carbonate sapropel is not suitable for obtaining humic preparations due to the low yield of humic acids; its scope is the use as a part of feed additives or as a soil deoxidizer. An experimental batch of a humic preparation with established optimal parameters has been produced, which has been tested with a positive effect in the field on plot experiments with winter barley and triticale. The preferred option for using a liquid humic preparation isolated from a mixture of peat and sapropel is the pre-clotting of seeds with the optimal concentration of the preparation for this purpose – 0.07–0.10 %. For irrigation under the root the concentration of the drug is 0.004–0.006 %. The humic preparation "Tosagum" was developed, which passed the necessary two-year tests on various crops in specialized centers of the National Academy of Sciences of Belarus.
