ABSTRACT:
The invention provides a method for improving the nature of soil in a salty land not suitable for agriculture by forming a moisture barrier in the soil with formation of a water-impermeable layer of soil underground. The method comprises sprinkling a water-soluble polymer, e.g. a copolymer of acrylic acid, or polymer blend including, for example, polyacrylic acid, capable of being insolubilized by interacting with the salt, preferably, in an aqueous solution over the salty land so that a water-impermeable layer underground is formed by the insolubilized polymer together with the soil particles.
