The article contains data on artificial soil structurants, which provide good productivity and improve drainage ability of reclamation systems especially on heavy mineral soils which can improve permeability fillings in water-absorbing elements due to structurants. It is found how ameliorants increase water-absorbing ability, porosity and structural properties of the soil. Some soil structurants are selected as the most acceptable to water-absorbing drainage devices on heavy soils and beneficial.
