Influence of fertilizer norms on root mass, nutrient quantity and chemical composition of lucerne

The results of the effect of fertilizers on the root mass, chemical composition and amount of alfalfa nutrients Medicago, (Fabaceae). Along with this, when the root mass is decomposed, the soil is enriched with mobile phosphorus compounds. It was found that the application of mineral fertilizers in the ratio of N60P90K60 significantly increases the root mass. An increase in root mass, along with an increase in organic matter, has a positive effect on the amount of nutrients in the soil, improves water-physical properties and increases soil fertility. 125.7-235.8 kg/ha of nitrogen, 26.1-58.7 kg/ha of phosphorus and 81.1-163.3 kg/ha of potassium enter the soil.
