Abstract
Abstract The invention relates to a method of stabilizing the soil and preventing erosion. According to the invention such a method is characterized by treating the soil with a mixed product of a pre-gelatinized starch and 0.5-5% by weight, calculated on the dry starch, of a surfactant compound which contains an unbranched saturated alkyl group and is selected from the alkyl sulfates having 10-16 carbon atoms, the alkyl sulfonates having 10-16 carbon atoms and the fatty acid alcohols having 8-12 carbon atoms. The invention also relates to said mixed product.
