The invention relates to the utilization of ecologically compatible surface active agent compounds from the class consisting of water-soluble O/W-type alkyl(oligo)glycoside compounds (APG compounds) by applying the latter on the surface of the soil as additive for preventing nitrate leaching from the area of the plant roots in cultivated lands during sprinkling and/or irrigation. Preferably, the APG compounds are applied in the soil together with lipophilic saturated and/or olefinic unsaturated hydrocarbon radicals and aerobic and anaerobic degradable organic compounds having fatty structures.

L'invention concerne des composés tensioactifs écologiques de la classe des composés alkyl(oligo)hétérosides de type aqueux (composés APG). On les applique à la surface de la terre comme auxiliaire afin d'empêcher les lessivages de nitrates issus de la zone de la racine des plantes dans les sols cultivés lors de l'irrigation par la pluie et/ou lors de l'arrosage de ces sols. On applique sur les sols, de préférence, des composés APG associés à des groupes hydrocarbures lipophiles saturés et/ou oléfiniquement insaturés et aussi des composés organiques biodégradables par aérobie comme par anaérobie.
