The effect of stabilizing additives on the water resistance and transition humic substances in water solution from granulated organomineral fertilizers
Abstract
The effect of stabilizing additives on the water resistance of granular organomineral fertilizers with a high potassium content has been studied. It is shown that the use of stabilizing additives (NH4)2CO3 and Ca3(PO4)2 in an amount of 2.5–5.0 % and a drying temperature of 120 ºC makes it possible to ensure the water resistance of granules up to 90 %, increases the transition of humic substances into a biologically active water-soluble form and reduces environmental pollution by plant nutrients. These additives contain components of nutrients for plant growth and development in their composition and do not lead to possible contamination of soils in comparison with polymer materials widely used for these purposes.
