Organomineral fertilizers (OMF) are high-quality and highly effective fertilizers that combine organic and inorganic nutrients in one granule, which allows you to get a much greater agrochemical effect compared to their separate use due to the balanced consumption of macro- and micronutrients by plants. OMF contain humic compounds, which are not only stimulants, but also contribute to an increase in the humus content in the soil, intensify the activity of soil microorganisms, improve the water and air regime of the soil, and structure it.
Under certain conditions, mineral compounds form organomineral complexes with humic acids, which lock up nitrogen in an exchangeable form and reduce its mobility, and phosphorus is converted into an easily digestible form. Due to the gradual release of nutrients from organomineral complexes, OMF provide plants with a stable diet throughout the growing season, which makes it possible to reduce their application doses by 1.2-2.0 times, compared to mineral fertilizers, by increasing the coefficient of nutrient utilization to 90 % and more.
JSC NIUIF has developed a technology of a fundamentally new OMF grade on the basis of environmentally friendly, specially processed lowland peat with 20-25% decomposition degree and not more than 20% ash content. The technology has been developed for standard production flowsheets that can be implemented at existing mineral fertilizer production facilities or at newly created plants in places where organic waste accumulates and includes the following main stages:
Various mass transfer processes and biological activation of organic matter with the formation of organomineral complexes occur as a result of thermomechanical treatment.
OMF technology allows to widely vary the ratio and content of nutrients, the amount of organic component can range from 30 to 70% of the mass. If necessary, there is a possibility of introducing magnesium-containing additives and micronutrients into the fertilizer composition, which allows to produce "direct effect" fertilizers.
The product consists of agglomerates ranging in size from 2 to 5 mm, which are less spherical in comparison with granular mineral fertilizers, obtained according to flowsheets with drum granulator-dryer or ammonizer-granulator.
JSC NIUIF, together with JSC Biysk Chemical Plant, has developed a wide range of OMF. Large-scale agrochemical tests and industrial use of OMF have shown their high efficiency when applied to various crops - vegetables, cereals, fruits, berries and flowers. OMF are also successfully used in greenhouses for preparation and filling of soils, especially for growing seedlings and green crops. OMF are proven to be highly effective when growing flowering plants in greenhouses. Due to OMF application, more robust rose bushes, stems are formed, the color of flowers is brighter, and the variety of flowers increases. The number of cut flowers increases by 25-30%.
Nowadays, JSC NIUIF has a modern scientific and technical base that allows to carry out a full scope of works on the development of production technology for different OMF grades using various organic raw materials and researching their properties, taking into account the customer's requirements:
