Efficiency of foliar fertilization of soybeans with microelements (review)

Basing on domestic and foreign scientific literary sources, we described a physiological role of microelements and peculiarities of their consumption with plants. A unique functional role of molybdenum, zinc, manganese, boron, and ferrum in plant metabolism is characterized. Data on efficiency of the foliar fertilization with microelements of soybean plants are considered. Optimization of soybean plants nutrition in ontogenesis by the foliar fertilization with microelements promotes increase of plants viability, pod and seed quantity. The peculiarities of stimulating and protection effects of the different microfertilizers containing a complex of Fe, Mn, Zn, Cu, and Ca in a chelating form, and B and Mo in a mineral form are analyzed. In all researches, a positive impact of a single foliar fertilization with molybdenum on soybean yield is stated. The data on dates of the foliar fertilization with microelements of soybean plants are quite different, and there is no information about advantages of a concrete date of treatment.
