Summary: The three-year research findings prove that foliar nutrition with trace elements influences the dynamics ofleaf surface formation, dry matter accumulation, and soybean photosynthetic net productivity under theWestern Forest-Steppe conditions of Ukraine. It was found out that foliar nutrition with the particular traceelements could enlarge the soybean leaf surface area, chlorophyll content and dry matter yield. During theexperimental studies, a positive effect on increasing the leaf surface area in soybean crops during the end offlowering was found in the variants where copper, iron and molybdenum-containing fertilizer were applied.The leaf surface area in the variant where copper was applied reached 46.3 thousand m-2 ha, which confirmsthe importance of copper in the formation of sugars and protein, direct participation in the process ofphotosynthesis. On the basis of the conducted researches it is established that in general on the amount ofchlorophyll in soybean leaves foliar feeding has a significant effect. The average chlorophyll content insoybean leaves was 1.10 mg-2 g of raw weight. The dynamics of dry matter by phases of growth anddevelopment of soybeans is established. Soybean produced the maximum amount of dry matter duringgrain ripening. Thus, 7.59 t-1 ha of dry matter was formed during the control.
