Graphical Abstract: The results of different experimental modalities of residues from biochemical plants which function on the basis of hydrolysis (hydrolytic lignin, hydrolytic slime) as black soil solonets fertilizer and amendment are presented in the given paper. From the ecological and economic points of view, a new technology of chemical amelioration of alkaline soils with excessive administration of components from hydrolytic residues as soil ameliorators is founded.
