Abstract
Soil conditioning compositions in which the active component is a reactive tenside being (a) condensation products, having a molecular weight under 15,000, of one or more of (i) ethylenediamine, diethylenetriamine, propylenediamine, dipropylenediamine, guanidine, dicyandiamide, N-aminoethyl alkylamines, N-aminoethyl alkyleneamines, N-aminoethyl alkyldienamines, N-aminopropyl alkylamines, N-aminopropyl alkyleneamines, N-aminopropyl alk-dien-ylamines, imidazoline, imidazole, 1-aminoethyl-imidazoline, 1-aminoethyl-2-alkyl-2-imidazoline, and 1-aminoethyl-2-alkyl-2-imidazoline, and 1-aminoethyl-2-alkylene-2-imidazoline, with one or more of (ii) formaldehyde, acetaldehyde, propionaldehyde, C.sub.2-6 dihalogenealkanes; (b) alkyl- or alkylcarboxyamide end group-containing derivatives of reactions between the components of (a) which are partially or totally alkylated with C.sub.1-2 chain compounds having a molecular weight under 15,000, and (c) water-soluble condensation products of urea with formaldehyde, acetaldehyde, propionaldehyde, or dihalogenealkanes, and (d) acid addition salts of (a), (b), and (c). Process for using these reactive tenside-containing compositions involve applying the compositions to the soil.
