Abstract
Method for the desalination and reclamation of irrigated soils through application to the soil of minute amounts of one or more anionic compounds having threshold properties in dilute aqueous solution.
Claims4
A process for reducing harmful effects of alkaline deposits in irrigated soils comprising applying to the soil an aqueous solution of an anionic polymaleic anhydride compound having threshold properties, said anionic compound or neutral salt thereof being applied in a quantity of from about 0.1 pound to about 25 pounds per acre of land applied directly to the soil prior to irrigation or by incorporation into irrigation water applied to the soil over a period of from about 4 to about 96 hours.
Use of an anionic polymaleic anhydride compound having threshold properties or the neutral water soluble salts thereof to treat irrigated soil, said anionic compound or neutral salt thereof being applied in a quantity of from about 0.1 to 25 pounds per acre over a period of from about 4 to 96 hours and being applied directly to the soil prior to watering or with water.
