FIELD: mineral fertilizers.
SUBSTANCE: invention relates to complex mineral fertilizers with trace elements based on naturally occurring zeolite and selenium, which is suitable to raise quality of wheat grains and enrich them with selenium on light chestnut soils. Process comprises mixing mineral fertilizer (N2.9P2.3K2.0) and clinoptilolyte-containing tuff divided to 1-2 mm and bearing selenium in its matrix, which was introduced by impregnation of tuff in sodium selenite solution at tuff-to-solution weight ratio 1:10 for 24 h.
EFFECT: improved quality of wheat grain, reduced toxicity of selenite (decomposition of cellulose), and enabled enrichment of produce with selenium.
