COMPOSITE ION EXCHANGE SUBSTRATES BASED ON POLYMERIC ION EXCHANGER AND NATURAL CLINOPTILOLITE
Abstract
Two composition substrates for growing plants were obtained by mechanical mixing of EDE-10P ion exchange resin in nitrate and phosphate forms with a natural clinoptilolite in potassium form. The substrates were tested in the biological experiment on continuous successive growing grass Lolium perenne L. on a fruitless sand with its 2% content without adding fertilizers. The productivity of the substrate was ~0.5 kg of dry (~5 kg green) overground biomass per kilogram of the ion exchange substrate, which is on the level of standard ion exchange substrate Biona®.
