In the control variant of the soybean "Nafis" without the use of mineral fertilizers and microelements, the leaf area was 45.6 thousand m2 / ha. Under the influence of microelements, the leaf surface was 51.0-56.4 thousand m² / ha. The highest indicators of micronutrient exposure were observed in moderately used variants of sulfur and manganese. Under the influence of macro and micro fertilizers, the leaf area of “Nafis” variety increased by 3.4-10.8 thousand m2 / ha or from 6.9 to 19.1%.
