Abstract

Studies conducted to study the effectiveness of the introduction of micro-deposits of silt into the soil as part of organo-mineral fertilizers in combination with conventional mineral and organic fertilizers have shown that the accumulation of nutrients in the soil. The best options affecting agronomic indicators were application doses in the amount of 20-25 t/ha. Taking into account more effective results for use in production, it is recommended in these soil-hydrogeological conditions to apply silt deposits at a dose of 25 t/ha, cattle manure 10 t/ha and the introduction of mineral fertilizers at a dose of – N88P43K46.
