FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Agent for reducing mobility and solubility of arsenic compounds in soil contains a composition of silicon and iron preparations, wherein the silicon preparation is amorphous silicon dioxide with surface area of 30 m2/g to 400 m2/g, which is selected from a group consisting of natural silicon dioxide, synthetic silicon dioxide, silicon obtained from waste industry, where iron is used as iron (III) oxide, wherein ratio of iron and silicon in weight ratio is from 1/10 to 1/30.
EFFECT: invention reduces arsenic toxicity to living organisms and arsenic mobility (solubility) in soils and grounds.
