description 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 when placing electrodes in alkali solution containers and commutating polarities of electrodes every 5-60 sec. ^ EFFECT: enabled large-scale preparation of stable metal oxide hydrosols. ^ 10 ex
