The article presents the results of studies of the process of reagent treatment of biodegradable organic waste of livestock complexes for the purpose of their agricultural use. The basic laws of the process of separation into liquid and solid fractions using oxalic acid are determined and analyzed; optimal doses of reagents; the dependence of changes in the properties of the fraction at various stages of treatment with calcium carbide slurry, comparing them with indicators obtained using lime milk, superphosphate and phosphogypsum.
