FIELD: agriculture, pesticides. SUBSTANCE: composition has desalting agent as an active component that is taken from the following compounds: (I) , (II) and (III) R¹⁷[R¹⁸PO(OH))]_2-5 where: R¹ - hydroxyl, COOH, C₆H₄-COOH, NHC(O)-R²⁰--COOH, hydroxyphenyl, COO-R⁹, or phenyl; R² - hydrogen or COOH; R³ - hydrogen or C₁-C₄-alkyl; R⁴ - hydrogen or C₁-C₄-alkyl; R⁵ - hydrogen, COOH, C₆H₄-COOH, NHC(O)-R²⁰-COOH, hydroxyphenyl, or phenyl, OR¹⁰ hydroxyl or pyrrolidone; R⁶ - hydrogen or COOH; R⁷, R⁸- - hydrogen or C₁-C₄-alkyl; R⁹, R¹⁰- - hydrogen or C₁-C₄-alkyl; R¹¹, R¹⁴ - hydrogen or CH₃; R¹², R¹³ - hydrogen; R¹⁵ - hydrogen, hydroxyl or C₁-C₄-alkyl; R¹⁶ - hydrogen or C₁-C₄-alkyl; R¹⁷ - N, NR¹⁹N; NR⁹NR⁹N; R¹⁸ - C₁-C₄-alkyl; R¹⁹ - C₁-C₆-alkyl; R²⁰ - C₁-C₄-alkylene; R¹ and R² together - anhydride; R⁵ and R⁶ together - anhydride; m and n = 3-100 independently; p and q = 0-3 independently, and also pesticide or substance enhancing absorption of nutrient compounds. Pesticide has methyldithiocarbamate sodium as an active component and composition has additionally surface-active substance triethanolamine dodecylbenzenesulfonate. Composition has about 23.3% polymaleic acid an aqueous solution, about 13.3% triethanolamine dodecylbenzenesulfonate and about 63.4% water. Composition containing substance that enhances absorption of nutrient compounds is taken from the group, NPK = 10-34-0 and has nitrogen and phosphorus at ratio = (3-4):1. Composition has desalting substance and substance enhancing absorption of nutrient compounds at ratio = 1: (216-720). Composition is used for soil treatment. EFFECT: enhanced effectiveness of composition. 7 cl, 2 tbl
