Effects of mineral fertilizers in growing lucerneon chernozeme lead Western caspian Caucasus

The results of field experiments fulfilled under conditions of ordinary chernozem are presented, as well as the evaluation of defecate effect on soil properties, the content of nutrients in maize plants and its productivity. The introduction of defecate in the norm of DT 50 t/ha had the most positive effect on the content of mineral nitrogen in the soil (ammonium and nitrate forms of its compounds), mobile forms of phosphorus and potassium, as well as nitrogen, phosphorus and potassium in plants, which ensured the fullest realization of corn potential productivity, grown for grain. Increasing standards defecate - DT 25; 50; 75; 100; 125 and 150 t/ha contributed to yield increase, which, depending on the amount of meliorant, varied from 63.2 to 67.8 c/ha. The greatest increase of 9.4 c/ha (15.9%) with the best grain quality was ensured by defecate application in the norm of 50 t/ha, while the content of protein in corn grain increased up to 10.9%, which contributed to protein harvesting increase by 166.7 c/ha. The content of nitrogen, phosphorus and potassium in maize plants is greatest at the beginning of growth and development of culture. Actively growing young corn plants are enriched with this element. The content of nitrogen and phosphorus in the vegetative mass and in the grains was the greatest when the defecate was introduced in the norm of DT 50 t/ha - 2.65; 0.36 and 1.89; 0.56% of dry weight. Unlike nitrogen and phosphorus, the content of potassium in corn kernels is low, and it accumulates in the leaves and stems of plants.
