The market of mineral fertilizers is developing rapidly, which contributed to the growth of agricultural production in general and the growth of demand in the world market in particular. As a result, the supply of mineral fertilizers on the market, which is formed due to its own production and import of products, grew. Chemical companies, taking into account the current situation, have shifted from the insolvent domestic market to the world market, as a result of which this segment has provided, along with the metallurgical industry, a significant share of foreign exchange earnings over the past decade. Mineral fertilizers are an important source of nutrient return to the soil and the basis for modern modern technologies and profitable agribusiness. In recent years, Ukraine has seen an increase in the use of basic types of mineral fertilizers, as well as an increase in the application of complex fertilizers. Demand for fertilizers in Ukraine is formed by farms of various organizational and legal forms and sizes of land use, including large agricultural holdings, where considerable attention is paid to the intensification of agricultural production.  In the usual technological mode, the neutralization of phosphoric acid in the apparatus of the high-speed evaporator-evaporator (SAV) is carried out with liquid ammonia. Liquid ammonia in the SAV apparatus first evaporates, and then gaseous ammonia reacts with phosphoric acid. The neutralization process results in a low-concentration ammophos pulp. It is established in the work that during the research of ammophos production in the conditions of vibrogranulation the technological process is improved due to the installation of more optimal nozzles of the BGS apparatus. The characteristics of raw materials, finished product and auxiliary materials are analyzed; physico-chemical bases of the process. Selected technical characteristics of the main and auxiliary equipment. According to the results of the research, it is proposed to install a transport nozzle, to improve the optimal conditions of the technological process, structural elements of the main devices.

The article presents a study of centrifugal distributors. The advantages and disadvantages of their use are identified. Based on this, in order to improve technological means for the surface application of mineral fertilizers, it was proposed to develop a self-loading distributor for solid mineral fertilizers from soft containers, which in an aggregate with energy means would perform the functions of transporting mineral fertilizers to the field, loading them into the distributor bunker and their distribution over the surface of the field. It proves that the topic is relevant and is of great economic importance. This article offers a description of the device, the principle of operation and its technical characteristics. It also presents the sequential operations of the technological process: loading, transportation of fertilizers to the field and the very introduction of mineral fertilizers. The purpose is to improve the operational and technological characteristics of the self-loading fertilizer distributor, which is provided by the knives installation scheme, their shape, which allows obtaining a consistently large opening for the release of fertilizers and is equipped with a dressing grid. The proposed design and technological solution allows the distributor being selfloaded with solid mineral fertilizers packed in soft disposable containers weighing up to 1 ton, using a lift installed at the rear of the tractor frame, cutting the bottom of this container and uniform feeding of fertilizers to the spreading disc. In this case, the upper part of the cover of the soft container acts as a part of the distributor bunker, increasing its useful volume

When using the conventional coulters for applying organic-and-mineral fertilizers, reliable technological process cannot be ensured unless a fertilizer funnel is adapted to such fertilizers. (Research purpose) Determination of the parameters of an improved coulter for introducing organic-and-mineral fertilizers. (Materials and methods) The authors conducted theoretical studies using the methods of theoretical and agricultural mechanics, as well as analytic geometry. They also considered the horizontal flow of soil particles under the action of the pointed part of a leg and made diagrams of the progressive speed of a cultivator depending on the cutting-point angle of the coulter leg at friction angles of 25, 30, and 35 degrees. (Results and discussion) An analytical relationship was obtained to determine progressive flowability of organic-and-mineral fertilizers through a coulter funnel. The author also found the cutting-point angle of a coulter leg for introducing fertilizers at a certain depth. In this case they neither stick to the coulter surface nor pack up before entering it. The optimum diameter of the fertilizer funnel was determined as well. (Conclusions) It has been proved that the cutting-point angle of a working tool leg for introducing mineral and organic-and-mineral fertilizers developed according to the research should range from 54 to 66 degrees. The authors have determined that an easy flow of fertilizers can be ensured if the diameter of a fertilizer funnel of a coulter should be not less than 43 millimeters.

Machines used in world practice for surface application of mineral fertilizers are often equipped with centrifugal devices with vertical or horizontal location of the axis of rotation. Having high productivity and reliability of technological process, they cannot always provide reception of a necessary dose and uniformity of scattering of fertilizers on width. In Ukraine, currently produced machines for the application of mineral fertilizers, which we have not previously produced. Since about 2/3 of all available mineral fertilizers, as well as most of the limestone and gypsum-containing materials are applied in a continuous manner, it is necessary to have a certain fleet of machines for applying fertilizers available to consumers. Fertilizer application in a continuous manner is carried out by land and aviation. One of the main agrotechnical requirements for machines for the application of bulk materials (mineral fertilizers) is their uniform distribution on the field surface. From uneven application of fertilizers, the reduction in grain yield reaches 10 ... 15%. The main disadvantages of the machine for applying mineral fertilizers are: imperfect design of the spreading mechanism, which leads to uneven scattering of fertilizers on the field surface; a large number of gears, which affects the metal content and cost of manufacture and complicates the design. Chain transmissions that drive the spreading device and the conveyor (during operation the chain is stretched, which requires the use of tension rollers, and take-off from the sprockets, especially on the drive of the spreading device); significant uneven application of fertilizers due to imperfect design of the spreading disc. The main reason for the low quality of fertilizer distribution by scattering machines, most researchers see a significant impact on the technological process of external random factors: field relief, wind speed and direction, humidity, elastic, frictional, hygroscopic and particle size distribution of fertilizers. Therefore, the improvement of the technological process of fertilizer scattering, in order to ensure a given uniformity of their distribution on the field surface in the conditions of real functioning, is an urgent scientific and practical task. In order to eliminate these shortcomings, a new spreading working body is proposed.

The use of centrifugal disk fertilizer spreaders, the axes of which are set obliquely, in the technological process of mineral fertilizers provides an increase indicators characterizing the spreading of technological material in the direction of its scattering, at a greater distance than fertilizer spreaders with vertical axis of rotation. Thus, the hypothesis of the possibility of increasing the working width of the machine for applying mineral fertilizers by equipping such machines with centrifugal disk fertilizer spreaders, the axes of which are set at an angle, is confirmed. Experimental research was conducted using the developed methods and current state standards, regression analysis, statistical methods of processing research results, standard and specially designed experimental equipment. The calculations were performed using the software environment Microsoft Office Excel 2007. As a result of experimental researches it is established that the centrifugal disk fertilizer spreaders which axis is placed inclined, reliably provides performance of technological process at change of frequency of rotation of its disk from 600 to 1000 rpm and changing the angle of installation of the disk to the horizon from 0o to 30o. For all studied kinematic modes of operation of the new working body, the effective scattering range of mineral fertilizers and the distance from it to the tray with the maximum share of the mass of sown fertilizer increase most rapidly with increasing disk angle to the horizontal plane from 0o to 10o, and least when changing the angle within 20o - 30o. The best indicators of fertilizer application both in terms of working width of capture and in terms of uneven application of fertilizers are provided at the angle of inclination of the disk of the new working body to the horizontal plane within 25o-30o.

Органоминеральные удобрения, содержащие гуминовые вещества, нашли широкое применение в современном сельскохозяйственном производстве. Их применяют для повышения урожайности сельскохозяйственных культур и качества получаемой продукции, снятия стрессовой нагрузки от обработки пестицидами, повышения плодородия почв и т.д. Эффективность использования удобрений на основе гуминовых кислот во многом определяется технологиями их производства, которые можно разделить на химические, физические и комбинированные. Анализ существующих технологий производства органоминеральных (гуминовых) удобрений показал, что большинство из них имеет ряд недостатков. К ним можно отнести длительность, сложность и многоэтапность технологического процесса, энергетическую и экономическую затратность, сложность аппаратурного оформления, невозможность получения конечного продукта с заданными стабильными характеристиками. В связи с этим разработка эффективных инновационных технологий производства органоминеральных удобрений из органического сырья (торфа, биогумуса, сапропеля и бурого угля) является весьма актуальной. Учеными института был разработан способ производства органоминеральных и комплексных на их основе удобрений, который позволяет повысить эффективность технологического процесса и качественные показатели получаемых удобрений. Согласно предлагаемому способу сырье проходит предварительную подготовку (измельчение, просеивание, гидратация и отделение нерастворимых включений), после чего подвергается щелочной экстракции и кавитационному диспергированию до момента прекращения активного образования солей гуминовых и фульвокислот. Далее суспензия готовых органоминеральных удобрений проходит систему многоступенчатой очистки, а затем, для получения комплексных удобрений, в поток органоминеральных удобрений дифференцированно вводят питательные микроэлементы. Для осуществления данного способа разработана схема технологической линии по получению органоминеральных и на их основе комплексных удобрений, представляющая собой комплекс оборудования, не требующего дополнительной модернизации при переходе с одного вида сырья на другое.Organicmineral fertilizers containing humic substances are widely used in the modern agricultural production. They are used for increasing crops yields and quality of the products, reducing stress effect from pesticide treatment, improving soil fertility, etc. Efficiency of applying fertilizers based on humic acids is highly dependent on the production technologies, which can be subdivided into chemical, physical and combined technologies. An analysis of the existing technologies of producing organicmineral (humic) fertilizers has shown, that the most of them had a number of disadvantages, including long duration, complexity and number of stages of the technological process, high economic and energy costs, need for non-standard equipment, impossibility of producing a final product with required stable characteristics. In this context, development of efficient innovative technologies for producing organicmineral fertilizers from organic raw materials (peat, biohumus, sapropel and brown coal) is highly important. Research workers of the Institute have developed a method for producing organicmineral fertilizers and complex fertilizers on their basis, that facilitates the improvement of efficiency of the technological process and qualitative characteristics of the fertilizers being manufactured. This method involves pretreatment of raw material (grinding, screening, hydratation and extraction of insoluble inclusions) with the following alkaline extraction and cavitational dispersing until termination of active salification of humic and fulvic acids. After that, the suspension of organic-mineral fertilizers passes through multistage treatment system, and then micronutrients are differentially introduced in the flow of organicmineral fertilizers to obtain complex fertilizers. For the application of this method the authors have developed a layout scheme of a process line for producing organicmineral fertilizers and complex fertilizers on their basis:an equipment system, that does not need modification in case of changing raw material.

Research methods: theoretical (analysis and synthesis of information resources); experimental field; statistical (mathematical processing of research results) according to generally accepted methods. Results. Experimental studies of the influence of the speed modes of the injector wheel of the DRAGON 6000 applicator for application of liquid nitrogen fertilizers CAS on the quality of the technological process were carried out. It is established that during radical fertilization with liquid fertilizers of corn crops with a row spacing of 70 cm the unit is able to provide a daily yield of 120 hectares in 16-row performance and projected 180 ha - in 24-row, provided proper organization of work and staff training. It is noted that in the conditions of growth of prices for mineral fertilizers and climate change introduction of ecological approaches and resource-saving technology of entering CAS on the basis of the DRAGON 6000 applicator is an urgent task which will allow to compete successfully in the world market. Conclusions. Analytical review of domestic and foreign information resources confirms that the technology of subsoil application of liquid mineral fertilizers, in particular urea-ammonia mixtures (CAS), compared with the application of dry and other liquid fertilizers, is becoming more widespread due to better efficiency, which is a derivative of plant nutrition, rational positioning of fertilizers at the required depth, minimization of evaporation losses, improved drought resistance in the cultivation of crops, and also has significant benefits by reducing losses of active substance, ease of adjustment and management of the work process. Studies have confirmed the possibility of providing the presented design of the machine a constant depth of penetration of needles into the soil with a wide range of humidity and different speeds, as well as the ability to choose rational protection zone for cultivation of corn plants without damage to achieve acceptable efficiency of liquid fertilizers. LLC "ROPA-UKRAINE" presents to the market to consumers the applicator of the Ukrainian production DRAGON 6000 which passed production check on the area of 500 hectares during continuous entering of liquid fertilizers of CAS on vegetative plants of wheat and in the course of interrow (radical) entering of CAS on corn crops. 1100 hectares.
