Abstract

Two polymer soil ameliorants were tested: one-component anionic hydrolyzed polyacrylonitrile (HYPAN) and two-component interpolyelectrolyte complex (IPEC) composed of HYPAN and cationic poly(N,N-diallyl-N,N-dimethylammonium) chloride with an excess of the anionic polymer. Aqueous solutions of HYPAN and IPEC were applied to the sandy loam soil; after drying, a protective polymer-soil coating was formed on the topsoil. These coatings were subjected to a series of tests with the following main observations: (a) The coatings exhibited mechanical strength, ranging from 2.9–4.1 kg cm−2 for HYPAN formulations to 5.6–8.2 kg cm−2 for IPEC formulations. (b) In the laboratory, all coatings demonstrated 100% resistance to wind erosion at an air flow speed of 72 km h–1. After re-watering, a 8–16% loss for the HYPAN-treated soil and a 1–2% loss for the IPEC-treated soil was found. (c) With the erosion tray, the effective resistance of the IPEC-treated soil to a water flow of 0.4 m s−1 was shown. (d) In the field, the application of polymer formulations did not significantly influence the growth, development or nutritional value of potatoes. (e) The polymers did not affect the biodiversity of soil bacteria. These findings are significant for the development of effective and ecologically friendly polymer ameliorants.
