Chemical analyzes have shown that the fertilizers affects the nutrient content of plants. Cotton fertilized with mineral fertilizers and manure, contained significantly quantity of phosphorus in the seeds, cusps, and stems. On fertilized soils, the largest increase in yield from the introduction of manganese and zinc was obtained - 2.0-2.8 q/ha of raw cotton in comparison with the control. In field experiment on meadow soil containing 40-45 kg/ha of P2O5, microelements mixed with nitrogen-phosphorus fertilizers also increased cotton productivity. The introduction of boron, molybdenum and zinc, the yield of raw cotton was 32.9, respectively; 32.1; 31.9 q/ha (control 29.7 q/ha). The increase in yield in relation to the control was from boron - 3.2, molybdenum - 2.4 and from zinc - 2.2 q/ha of cotton.
