Abstract
The article presents the results of obtaining complex liquid fertilizers and organomineral meliorant by stepwise oxidation of licorice meal. The solution containing humic acids and fulvic acids, isolated after the first stage of oxidation, was used to obtain a liquid complex fertilizer after adding urea, ammonium sulfate, ammonium nitrate, purified and ammoniated Extraction phosphoric acid. Also, the dependence of the properties of liquid fertilizers - saturated vapor pressure, density, viscosity, and crystallization temperature on the composition was determined; by mixing the remaining licorice meal with quicklime after secondary oxidation, high-molecular-weight organomineral calcium humate-containing meliorants were obtained.
