Effectiveness of use of zeolite in vegetable growing in the footdown zone of southeast Kazakhstan

Effectiveness of use of zeolite in vegetable growing in the footdown zone of southeast Kazakhstan Natural zeolites are widely used in agriculture both as independent fertilizers and as part of mixtures of mineral and organic fertilizers. Natural zeolites are crystalline nanoporous hydrated aluminosilicates. A modified zeolite fertilizer of prolonged action, enriched with macro- and microelements, was obtained by chemical and thermal Treatment of zeolite from the Shankanai deposit with ammophos dispersed to nanoscale sizes. The morphology and elemental composition of the new fertilizer were studied by X-ray diffraction. Zeolite introduced into the soil with mineral fertilizers leads to an improvement in the agrophysical properties of dark chestnut soil.
