ADVANTAGES OF USE OF THE GRANULAR ORGANIC-MINERAL SLOW RELEASE FERTILIZERS

Abstract

The necessity of using complex organic-mineral fertilizers with a given composition of components, which determine by agrarian and climatic conditions of growing crops, is considered. The possibility of using new beneficial components in the form of granulated organic-mineral fertilizers of slow release action and the useful properties of each component is determined.Key words: granule, composition, organic-mineral fertilizers, resource conservation, yield, prolonged action.The agro-industrial complex is one of the main sources of foreign exchange earnings in the structure of foreign trade of Ukraine, in addition to this, the agricultural potential has a significant export potential. As of 2018, the share of exported vegetable products in the overall structure of exports of goods amounted to 20.9% of the total volume. As a result, the development of this sector of the economy is one of the main issues for today. The potential of agriculture, especially crop production, is significantly dependent on the fertility of agricultural land, which in turn depends on the quality of fertilizers that are used, therefore the quality of fertilizers is not only important for the development of the industry, but also has an impact on the economic situation. Soil fertility has declined markedly due to irrational land use, erosion, dehumidification, soil mineralization and environmental contamination.The main advantage of this fertilizer is the higher efficiency of plant nutrition compared to traditional fertilizers, due to the release of useful components over a longer period. Slow down selection of useful components (prolonged action) is ensured by the layered structure of the granule and the uniform placement of useful components throughout the volume of granules OMF of a new generation during its moisture in the soil. Obtaining of this structure of the granule is possible with the application of a fluidized bed granulator. The use of waste from agricultural, food and chemical industries, as raw material for the production of new granular organic-mineral fertilizers of prolonged action, will solve the problems of reducing fertility of soils, preserving resources and the environment.There is a need for the creation and improvement of existing technology and equipment for the production of layered compositional organic-mineral fertilizers containing ammonium sulphate, humic substances, deoxidizing compounds and other useful components, the composition and correlation of which is determined by the agro-climatic conditions of cultivation. Application of a deoxidizing component, such as lime in organic-mineral fertilizers, will reduce the acidity of the soil and reduce the amount of separate application of lime
