Increasing the fertilizer dose from N100P80K40 kg/ha to N140P120K60 kg/ha did not contribute to an increase in mobile phosphorus in the soil, which indicates the property of phosphorus: when interacting with the soil, it forms poorly accessible compounds of phosphoric acid and is bound by the soil.During the growing season, some increase in the content of mobile potassium is observed in June-July and its gradual decrease by the end of the growing season. The application of mineral fertilizers improves the nutrient regime of the soil and contributes to an increase in the available forms of nutrients in alluvial meadow soils of the Astrakhan region. But the application of high doses of mineral fertilizers (N140P120K60 kg/ha) does not lead to an increase in the available forms of nutrients, compared with a lower dose.
