THE INFLUENCE OF THE HUMIC COMPOUND "BIOVIT" ON THE GROWTH AND  DEVELOPMENT OF SOY PLANTS CULTIVATED IN AQUEOUS NUTRITIOUS MEDIA

Humic compounds are a major component of organic fertilizers. In order to study the response of soybean (Glycine max(L.) Merr.) against the application of humic preparate Biovit, the experiment was conducted in vegetation vessels on the aqueous nutrious media. Supplementing the nutrient media with the humic compound Biovit reduced and, in some cases, completely eliminated the symptoms of nutrient deficiency, the plants not showing chlorosis and necrosis. The Biovite improves the physiological state of the plants against the lack of chemical elements. The most pronounced effects of the preparation of humic nature on the plants have been attested at the root system level. The major effects of the action of Biovit were established on the nutrient media with nitrogen and phosphorus deficiency, which demonstrates the substantial role of the humic compounds in the metabolization of these chemical elements.

Keywords: humic compounds, soybean, nutrient deficiency.
