The invention relates to the production of mineral-organic fertilizers. The mineral-organic complex granulated fertilizer comprises a mineral constituent and an organic constituent, wherein the fertilizer comprises enriched glauconite as the mineral constituent and mineral fertilizers in an aqueous solution as the organic constituent, with the following ratio of components: 70-90% by mass of enriched glauconite and 10-30% by mass of mineral fertilizers in an aqueous solution. The method for manufacturing a mineral-organic complex granulated fertilizer comprises mixing a mineral constituent and an organic constituent, wherein the mineral constituent used is a finely dispersed, enriched glauconite with a particle size of a maximum of 70 μm and a concentration of a minimum of 90%, to which an organic constituent is added, for which use is made of a 10-50% strength aqueous solution of mineral fertilizers with a specified, predetermined concentration, until a plastic mass with a moisture content of a minimum of 30% is formed, then granulating the mixture, drying the granules with air of a temperature of 60-70̊C to a moisture content of a maximum of 8%, pulverizing, sifting and sorting the granules according to particle size distribution, followed by bagging. The technical result is an increase in the effectiveness of prolonged action of the complex granulated fertilizer on rich soils owing to the ion-exchange properties, the unique micro-element composition, and the increased sorption capacity and content of granulated sorbent. |
