The effect of forms and concentrations on the water resistance of the microele- ments and biologic activity of granulated organomineral fertilizers
Abstract
The influence of forms and concentrations of trace elements in the composition of granulated organomineral fertilizers on their transition from granules to aqueous extract and its biological (growth-stimulating) activity was studied to substantiate the compositions and technology for new types of organomineral fertilizers obtaining. A significant difference in the value of the transition of microelements for the salt and chelated forms from granular organomineral fertilizers to the water-soluble form available for plants and the effect of temperature treatment of granules are shown. It was found that when copper and zinc were used in the form of inorganic salt, the maximum biological (growth-stimulating) activity was observed for low concentrations at the drying temperature of granular organomineral fertilizers at 90–125 ºС, for high concentrations – at 110 ºС. When using copper in chelate form, the maximum biological (growth-stimulating) activity was observed for low and high concentrations at the drying temperature of granular organomineral fertilizers at 25 ºС, for medium concentrations – at 90–110 ºС. When using zinc chelate, the maximum biological (growth-stimulating) activity was observed for low concentration at the drying temperature of granular organomineral fertilizers at 125 ºС, for high concentration – at 110 ºС.
