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_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_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.

Claims

1. A process for improving plant yield comprising applying to the soil in which the plant is to be grown an amount effective to improve plant yield of a reactive tenside selected from the group consisting of addition products, having a molecular weight under 15,000, of one or more of (i) guanidine and dicyandiamide, with one or more of (ii) formaldehyde, acetaldehyde, propionaldehyde, and C_2-6 dihalogenealkanes, acid addition salts of said addition products, and mixtures thereof.

2. A process in accordance with claim 1, wherein the reactive tenside is a compound having the formula

and having an average molecular weight of from 4,000 to 5,000.
