FIELD: agriculture.
SUBSTANCE: invention relates to methods for preparing soil improvement-destined solutions. Method of invention comprises ion exchange-mediated substitution of hydroxyl ions for salt anions in aqueous solution, which process is carried out between container with salt solution and container with alkali solution communicating through anion-exchange membrane. Ion exchange process is promoted by electrolysis proceeding when one electrode is placed in alkali solution container and the other in salt solution container and polarities of electrodes are commutated every 5-60 sec.
EFFECT: enabled large-scale preparation of stable metal oxide hydrosols.
