Abstract:
Fertilizer spreaders play a crucial role in evenly distributing granule fertilizer across palm plantations. However, in specific areas where growth conditions are unsuitable, fertilizer application becomes unnecessary. Therefore, this study aims to improve granule fertilizer distribution efficiency through enhanced fertilizer blade design. Using Finite Element (FE) simulation, the stress deformation and deflection of the existing spreader blade were evaluated. Meanwhile, Computational Fluid Dynamics (CFD) simulation was used to investigate the influence of spreader design on fertilizer projection speed and direction in the case of open and closed side discharge. The study revealed that the applied forces increased both the critical stress deformation and deflection. To ensure the fertilizer spreads properly over the desired area, the initial velocity had to be increased proportionally with an increase in the angle of direction. These findings contributed to a deeper understanding of the relationship between fertilizer projection velocity, spreader blade strength, and flow behaviour, enabling the reduction of waste in granule fertilizer, while enhancing the operational efficiency and reliability of fertilizer spreader.

Abstract:
There is no specialized equipment designed to spread granular cylindrical organic fertilizer in the soil. There are also no rational recommendations available on how to spread this type of fertilizer. Mineral fertilizer spreaders are most often used for spreading granulated organic fertilizer. However, these fertilizers are significantly different from mineral fertilizers. Due to these differences, organic granular fertilizers often are spread unevenly, and the fertilizer does not reach the required working width. Furthermore, the rate of spreading is not accurate, and the fertilizer is often crushed too much. The objective of this research is to develop a simulation model for granular organic fertilizer applications with a centrifugal spreader in EDEM (extended distinct element method) software. It is possible to develop a numerical model that corresponds to a real spreader, and to determine the key physical–mechanical parameters for the application of granular organic fertilizer. This model can also be used for evaluating the transverse uniformity of the fertilizer in the field (along the trajectory normal to the machine). The results of this research show that the distance traveled by the fertilizer granules partially depends on the particle size, initial speed, type of fertilizer and the parameters of the spinning discs of the spreader.

Abstract:
Due to the continuous creation of organic granular fertilizers of the new composition, there is a lack of knowledge about their properties and the influence of the norm on spreading efficiency. To increase the efficiency of the use of granular organic fertilizers, their spreading aims are to properly choose the most rational spreading parameters and fertilizer norms, considering the characteristics of the fertilizer. To determine this quickly and with lower costs, various theoretical models and computer programs are used to study the dynamics of fertilizer spreading. The purpose of this work was to perform theoretical and experimental comparative studies of the influence of the characteristics and dosage norms of granular fertilizers of poultry manure on the spreading efficiency. During the research, the physical properties of granular poultry manure fertilizers were determined, which have an impact on the quality of spreading. Experimental studies of fertilizer spreading were carried out using two centrifugal spreaders with the same parameters (Amazone ZA-M-1001 (spreading dosage norm, 200 kg ha−1 and 400 kg ha−1; driving speed, 10 km h−1) and ZA-M-1201 (spreading dosage norm, 600 kg ha−1, 800 kg ha−1, and 1000 kg ha−1; driving speed, 5 km h−1)). Before the fertilizer was spread, measurements were made of the flow rate of the spreadable fertilizer through one bunker shutter. Fertilizer application simulations were performed using the discrete element simulation program EDEM. Research has shown that spreading the studied granular fertilizers at the dosage norm of 600 and 800 kg ha−1 allows for the future expansion of the limits of spreading research using a spreading simulation. The most important directions of research would be the research of the spreader vanes’ shape, length, and rational settings positions, using the standard commonly used centrifugal spreader, after making small modifications of the spreader, to achieve that the spreader could spread larger norms of fertilizer or drive faster during spreading.

Abstract:
The article presents the results of the study to substantiate the angle of the vertical installation of the fertilizer spreader, which localizes the fertilizer between the rows of cotton. Based on the results obtained, a working body is developed for mixing organic and mineral fertilizers during intercropping. The movement of the fertilizer pieces along the X and Y axes was studied. The coordinates of the fertilizer pieces’ landing point on the working surface of the fertilizer spreader, their velocities, and motion equations of the fertilizer pieces in the next jump were created. As a result, the cotton grows equally and yields a good harvest. The movement of the fertilizer pieces and the movement and distribution of the fertilizer spreader along the working surface are studied. It was found that the vertical mounting angle of the fertilizer could be ɛ = 18˚.

Abstract:
Currently, various methods are used to apply fertilizer under the plow. At the same time, mineral fertilizers are applied to the soil surface after harvesting in our republic with Amazone ZA M-1500 brand disc centrifugal fertilizer spreaders. Immediately after sowing, the plowing operation is carried out with an SP-12 brand fourbody plough so that the applied fertilizers fall under the soil. This is how the operation is performed. The tractor is used twice to carry out this technological operation, which is economically inefficient and inconvenient on slopes. Thus, the centrifugal fertilizer spreader works unevenly. To eliminate this problem, a combined plough was developed in our laboratory. In order to calculate the economic efficiency of the combined plough, the economic indicators of the SP-12 brand four-body plough and the Amazone ZA M1500 brand fertilizer spreader were compared, and an economic efficiency of 1586.79 AzN (933.41,dollars $) was obtained. The article provides economic tables. The smooth and even distribution of mineral fertilizers in the field with the application of a combined plough increases the yield in grain growing from 26 cent/ha to 32 cent/ha minimally. If we calculate the cost of wheat at about 0.35 AzN (0.21 dollars,$) (per kg, then with 600 kg per hectare, it allows to obtain an economic yield of 210 AzN/ ha (123.53 dollars/ha), and an economic yield of 68040 AZN (40,023.53 dollars $) from 324 ha during the season.

Abstract:
Using fertilizers, in line with other agrotechnical activities, is one of the most important means for increasing soil fertility, as well as agricultural products performance. Domestic and foreign experience shows us that yield capacity can grow almost 1.5-fold due to fertilizers. Nowadays the surface type of using hard organic and mineral fertilizers by means of body spreaders is considered to be one of the simplest technically and most effective ways. Being the object of the research, the experimental mineral and organo-mineral granular fertilizers spreader is a van-type lowboy, equipped with a belt conveyor and a vertical rotor with a horizontal axis of rotation. In addition to load bearing characteristics, rotational movement of the operative parts in the casing of the rotary drum provides for air drag, which influences the trajectory of fertilizers flight. Pattern of fertilizer distribution, flight distance of fertilizer particles and horsepower input of the gear system depend on the design features of the operative parts of the pneumatic-mechanical rotor. The objective of the research is to define travel speed of fertilizer particles along vanes in case of constant fertilizer input with air drag in versions with radial position of vanes, bent backwards and forwards to some angle. The main research techniques are a graphical and analytical method and analysis of the component force which operates on the blade's surface. As for the drum with a diameter of 920 mm, at rotation frequency of 850 min-1, the best performance was shown by the through blade. They may reduce the friction force of the casing of rotor. Besides, they can concentrate fertilizers in the center of a blade, and achieve qualitative work of the fertilizer spreader, is ascertaining.

Abstract. The author proves that organic fertilizers, unlike the mineral ones, are capable of increasing yields over several years; they do not harm the environment and do not pollute the melon crop fields with nitrates. It has been clarified that their introduction is one of the most effective methods of humus conservation and soil fertility enhancement, which means obtaining fuller yields of high-quality melons and gourds. The NIIMESH researchers have developed a combined unit for local application of organic fertilizers for melons and gourds. (Research purpose) Conducting theoretical studies on the substantiation of the configuration of the working tools of a combined unit for local application of organic fertilizers. (Materials and methods) The author has conducted theoretical studies using methods of analytical geometry and theoretical mechanics. (Results and discussion) Analytical dependences have been obtained to determine transverse distances between furrow shapers used for applying organic fertilizers and making an irrigation groove, as well as longitudinal distances between the tractor's rear wheels and the furrow shapers applying organic fertilizers, between the furrow shapers and the fertilizer spreader, and between the fertilizer spreader and the furrow shaper making an irrigation furrow. (Conclusions) It has been determined that transverse distance between the working tools that make furrows for applying organic fertilizers should range between 0.9 and 1.3 metre, transverse distance between the working tools making an irrigation furrow and a furrow for the application of organic fertilizers is 0.45-0.65 metre. The optimal values of longitudinal distances have been found as well: between the tractor's rear wheels and the working tools making furrows for applying fertilizers – no less than 0.21 metre, between the tip of working tools and the fertilizer spreader – no less than 1.5 metre, and between the fertilizer spreader center and the tip of working tools making an irrigation furrow – at least 0.74 metre.

Abstract:
We report the experimental results of tests aimed at assessing the effects of different settings on the mean radius of mineral fertilizer distribution using a disc fertilizer spreader. Our aim was to improve the performance of fertilizer distribution in sustainable agriculture. Three types of mineral fertilizers with different physical characteristics, commonly used in agriculture, were considered: urea, calcium ammonium nitrate and ammonium sulfate. A complete randomization method based on a four-factor experimental model was used to study the influence of the functional and operational parameters on the mean radius of fertilizer spread. Fixed model analysis of variance showed that fertilizer type, vane configuration and disc angular velocity explained 91.74% of the variance of the spread mean radius, while linear multiple regression analysis highlighted that the fertilizer dust fraction and disc angular velocity had an overall effect of 82.72%, the former showing an inverse correlation as high as 72.77%.

碩士<br>國立臺灣大學<br>生物產業機電工程學研究所<br>107<br>The world’s population is constantly increasing, and with the change in eating habits, the demand for food has only increased. Modern agricultural technology must rely on science and technology. Mechanization is a efficient solution to the current shortage of farming land. For a large range of farming land, if the traditional manpower can be replaced by machinery, not only the efficiency will be improved, but also the application of fertilizer can be more precise and scientific. In the previous developed fertilizer spreaders, the width of the spread was affected by the speed, and that was one of the disadvantages. This research develops a fertilizer spreading mechanism that can be applied to drones in the future. Instead of the spinning mechanism, we try to use screw to transport the granular fertilizer, and then spread it with a straight-down mechanism. The results of the experiment show that the maximum amount of delivery per hour can reach 63.79 kg/hr.

Abstract:
碩士<br>國立屏東科技大學<br>熱帶農業暨國際合作系<br>103<br>Sugar apple is one of most important fruit tree in Taitung. Farmers usually applied fertilizer by hand, which is a hard work and very lobar-intensive. There were different kinds of fertilizer spreaders developed before, but none has been successfully used in sugar apple orchard because of price, mechanical stability, and other issues. We used a fertilizer spreader device with farm wagon developed by Taitung District Agricultural Research and Extension Station, Council of Agriculture, Executive Yuan for this research. Experiments were conducted to exam characteristics of the spreader, its fuel consumption and operation efficiency. The fertilizer experiment consisted of 3 treatments: using mechanical spreader three times with fertilizer 1600 kg/ha, using mechanical spreader five times with fertilizer 1440 kg/ha (90%), and hand applying three times with fertilizer 1600 kg/ha. The mineral content of soil and leaf before and after fertilizer treatment were analyzed and individual fruit weight was recorded. Results showed that the fertilizer spreader device with farm wagon can effectively apply different types of fertilizers in sugar apple orchard. The average operation rate is 1.43 ha/hr, which was 7 times of manual operation rate (0.2 ha/hr). The average fuel consumption was 1.93 l/ha. The soil analysis showed soil nitrogen content was not affected by different treatments. Leaf analysis showed all treatments can increase the content of N, P and K respectively, and using mechanical spreader five times with fertilizer 1440 kg/ha (90%) showed the largest effect. There was no significant difference among fruit weight. Based on the cost analysis, to purchase spreader machinery at 35,000 NT dollars and operate on a minimum area of 1ha could be more cost efficient than that of hand applying operation.

Abstract:
The variable rate fertilizer spreader was modified to control each pair of nozzles for spot-application of fertilizer only in plant areas of wild blueberry fields. The experiments were conducted to evaluate performance accuracy of modified variable rate granular (MVRG) fertilizer spreader. The results suggested that the MVRG fertilizer spreader performed efficiently in detecting bare spots/weed patches and clay filler application only in green grass/plant areas. Two wild blueberry fields were selected to evaluate the impact of MVRG spreader on nutrient leaching through small bare spots/weed patches. Management zones were delineated on the basis of slope variability. The MVRG spreader significantly reduced the nutrient loading in subsurface water samples collected from the bare spots/weed patches. Based on the results obtained, it can be concluded that the fertilization in wild blueberry fields using MVRG fertilizer spreader can result in the protection of subsurface water quality, thus protecting the environment.

Abstract:
Greater use of technology to assist aerial application of fertiliser will be of benefit to the topdressing industry and farmers. Benefits arise through automating the fertiliser flow control system; reducing off target fertiliser application, and managing fertiliser inputs based on the potential outputs of the farmland; thus increasing the profitability of hill country farming systems. A case for technology assisted application is developed by investigating the field performance of conventional and enhanced flow control systems and the effect of variable rate application on hill country pasture production. A single particle model that predicts flight trajectory from the particle force balance based on the aircraft groundspeed, axial and tangential propeller wash, wind characteristics and particle properties including sphericity was developed. Model predictions were compared to predictions from AGDISP 8.15. Results and trends were similar. The single particle ballistics model described above was extended to predict the lateral distribution of fertiliser after release from an aircraft. To achieve this, two parameters are important, the transverse flow profile of material leaving the hopper gatebox and the sphericity of the particles. Techniques for measuring these parameters are described and experimental results are presented for superphosphate. These data were used in the model to predict the lateral distribution pattern from a Gippsland Aeronautics 200C for a known discharge mass, which was compared to a measured pattern from the same aircraft for the same discharge mass. Good agreement between the shapes of the two distributions was found. The transverse distribution model provides a practical tool for optimising the design of spreaders, or optimum particle characteristics for a given spreader. It has the ability to predict the distribution profile of any particle size distribution from each, or all, of the spreader ducts. Culmination of the single particle and transverse distribution models led to the development of a deposition footprint model that was capable of predicting field application within a 25 ha trial site. The deposition footprint model was embedded inside a geographical information system and comparisons were made between the actual and predicted deposition across a series of transect lines. Good agreement was found. Following this, a comparison of the predicted field performance between an automated and manual control system were made. Economic benefits for a single application of superphosphate were identified through using automated control, where 10% less fertiliser was applied outside of the application zone when compared to the manually operated system. This equated to a net benefit of NZD $2800 for a 1500 ha hill country farming system. The value of improving the performance of a topdressing aircraft, on an industry level, was also examined. Cost/benefit analysis between a manual and automated system revealed a benefit of NZD $111,700 yr-1 for a single topdressing aircraft using the automated system. The economic impact of Variable Rate Application Technology (VRAT) is examined, using Limestone Downs as an example. The spatially explicit decision tree modelling technique was used to predict the annual pasture production over the entire Limestone Downs property. The resulting decision tree classes tended to follow the farm's digital elevation model. A series of six different fertiliser application scenarios were developed for comparison to a base line scenario using conventional aerial application techniques. VRAT outperformed the fixed rate applications in terms of pasture production and fertiliser utilisation. Full variable rate application and a model optimised prescription map, produced the highest annual pasture yield. Variable rate techniques were predicted to increase annual production and the spatial variability of that production. An economic analysis of the six production scenarios was undertaken. Farm cash surplus was calculated for each scenario and clearly revealed the benefits of using variable rate application technology. VRAT was found to be the most efficient and highest returning application method per hectare. Additional costs and increased charge-out rates were likely to occur under VRAT; nevertheless, the analysis indicated that significant financial incentives were available to the farmer. A sensitivity analysis revealed that even with a 20% increase in charge-out rate associated with VRAT, the farm's annual cash position varied by only $4500 (0.4%), suggesting the cost of implementing such a system is not prohibitive and would allow aircraft operators to add value to their services.

Abstract:
AbstractGlobal challenges of water scarcity and food insecurity justify sanitation approaches that utilize dry sanitation with the agricultural use of excreta. One such approach is urine-diverting dry toilets (UDDTs) that separate urine and feces at the source at the time of excretion, thereby efficiently sanitizing the feces without liquid by separating the urine. However, in practice, some people have an aversion to the agricultural use of human excreta. Although the resource value of human excreta can potentially drive the spread of sanitation, this can only be achieved when a sanitation system utilizing human excreta for agriculture is accepted and rooted in society. This chapter studies the long-term acceptability of UDDTs that were installed several years ago in Vietnam, Malawi, and Bangladesh, focusing on the fertilizer value of human excreta. The majority of UDDTs were continuously used in all cases. Physical conditions and usability were the primary reasons to use UDDTs. Proportions of the continuous use of urine were low in all cases, and the perceived fertilizer values of urine by UDDT users were significantly lower than those of feces in Malawi. The fertilizer values of feces and urine alone were not always a motivation to use UDDTs although that of feces possibly contributed to the continuous use of UDDTs in Malawi. Religious impurity was a major barrier to use of urine and feces in Bangladesh, although it could be overcome with clean conditions of UDDTs and appropriate socio-cultural context.

Abstract:
AbstractThis paper describes the outline of the video tutorial prepared for vegetation workers and relevant officers in Bhutan to learn how vegetation works are to be done in remote areas. The Japan International Cooperation Agency (JICA for short) took a project on cutting unstable slopes in Gangthangkha, Wangdue, Bhutan, so that they should be gentler than 45° to improve slope stability with vegetation works. Particularly stabilizing slopes along Prime National Highway No. 1 (PNH-1 for short) was the overriding priority because slope failures along this highway have reportedly occurred in rainy seasons. Before vegetation works were carried out on the studied slope of the project, the authors conducted germination tests to choose seeds and methods suitable for the vegetation works. They chose Paspalum Atratum, Ruzi grass, and GM mixed (Grass Mixture seed formulating of Cock’s foot 70% and Italian Ryegrass 30% of 100 kg) based on their test results. The soil thickness associated with sowing was set at 5 cm. The authors tried the following types of vegetation methods on the studied site. Type A is arranging on the slope stripes of soil mixed with seeds and fertilizer, Type B is spreading out a five cm-thick seeds-mixed soil layer over the slope, and Type C is transplanting germination beds. In conclusion, Type C is the best in terms of its performance because the whole slope is quickly covered with already grown plants. In Type B, it is not until grass covers the entire slope that the slope is finally stabilized. Type A is good for seeds-mixed soil stripes, but it takes time for the grass to spread gradually over the whole slope.

Abstract:
A fertilizer spreader machine is a mechanical device that distributes fertilizer evenly across a field or garden. This machine is commonly used in agriculture to ensure that crops receive the nutrients for healthy growth and a high yield. The spreader typically consists of a hopper, a spinning disc, and a spreading mechanism that distributes the fertilizer as the machine moves across the field. Some fertilizer spreaders may also include advanced features such as GPS technology to improve accuracy and efficiency. Using a fertilizer spreader machine can help farmers and gardeners increase productivity and reduce costs associated with manual fertilization methods. This project report focuses on designing and developing a fertilizer spreader machine for agricultural applications. The machine is designed to distribute fertilizers evenly across a field or garden to ensure that crops receive the nutrients for healthy growth and a high yield. The report covers the various aspects of the machine, including its design, fabrication, and testing. The design phase involved developing the specifications for the machine, selecting the appropriate components, and creating a 3D model using computer-aided design software. The fabrication phase involved building the machine, including the hopper, spinning disc, and spreading mechanism. The testing phase involved valuating the performance of the machine under various conditions, including different types of fertilizers, speeds, and terrains. The testing results demonstrated that the fertilizer spreader machine could distribute fertilizers evenly and efficiently and was a cost-effective alternative to manual fertilization methods. Overall, this project report provides a comprehensive overview of the design and development of a fertilizer spreader machine and its potential benefits for agricultural applications.

Abstract:
Smart fertilizer technologies enhance agricultural efficiency by accelerating processes, increasing crop yields, and minimizing environmental impacts. The primary objective of fertilization is to apply fertilizers as uniformly and precisely as possible across the soil surface. To increase fertilizer efficiency, fertilization techniques and technologies are constantly being improved, fertilizer quality is being improved, and optimal fertilizer rates are being selected. The appropriate fertilizer rate is influenced by the soil composition, its physical and chemical properties, and the specific requirements of the crops being cultivated. Uneven fertilizer distribution affects yields: it reduces fertilizer efficiency, increases nutrient losses, and has a negative impact on the environment. This article presents experimental studies of a centrifugal double-disc fertilizer spreader that can apply fertilizers at a variable rate. The research aimed to assess how the spreader maintained both the uniformity and application rate of the fertilizer. Comparative tests were conducted with mineral and organic granular fertilizers. The findings indicate that the spreader speed significantly affected the uniformity of fertilizer distribution across the soil surface. When applying mineral granular fertilizers, the most uniform distribution was observed at an application rate of 200 kg·ha-¹. In contrast, the uniformity of fertilizer distribution when applying organic granular fertilizers was optimal at a rate of 600 kg·ha-¹. The coefficients of variation calculated for both cases were within the recommended limits for optimal fertilizer application.

Abstract:
Spreading of mineral fertilisers on the surface of the soil is the most widely used and effective way to increase the harvest of agricultural crops. The new construction of a centrifugal fertilizer spreading apparatus with the spreading disc the axis of which is inclined to the horizontal plane, developed by the authors, allows for essential increase of the distance of mineral fertiliser particles from leaving the blades of the disc. Nevertheless, the constructive peculiarities of the inclined spreading disc require comprehensive substantiation of the parameters of the disc and feeding mineral fertilisers from the feeder and the tank. The aim of the research is substantiation of the working width of the machine for mineral fertiliser spreading and productivity depending on the constructive and kinematic parameters, as well as the place where the mineral particles will be deposited on the surface of the spreading disc that is inclined at the angle to the horizon based on the performed computer analysis of movement of particles along the surface of the disc of the centrifugal spreader. The present research has been performed using the methods of modeling, theoretical mechanics and higher mathematics, as well as the methods of calculation, using graphs and computer modeling. Based on the mathematical model, previously developed by the authors, for spreading mineral fertiliser particles and the obtained differential equations of the movement of mineral fertiliser particles along the disc of the inclined under an angle to the horizontal plane working body and equations of the absolute movement of the particle leaving the disc of the working body, computer calculations are performed. The graphs of dependence of the absolute speed of mineral fertiliser particles leaving the disc of the working body on the time and the above mentioned parameters have been obtained, on which the distance of the mineral fertiliser particle after leaving the disc blade of the working organ is dependent. The angle speed of the disc and radius of feeding have higher influence on the relative speed of the particle leaving the blade. Rational values of the radius of the fertilizer supply do not exceed 0.5 of the radius of the disk of the fertilizer spreading working body. Changing the angle of the disc within 0°…40° does not influence the dispersion time of the particles and the values of the relative and absolute speed of particles leaving the blade. Rational disc inclination values to the horizontal plane are within 20° … 30°.

Abstract:
The produced mineral fertiliser spreaders have the working width and productivity that do not satisfy today’s requirements in high-technology agricultural production. It refers also to the distance the mineral fertiliser particle can reach. We have developed a new centrifugal fertilizer spreading working tool with an inclined axis of rotation. It allows for increased distance of mineral particles at centrifugal spreading. The aim of the present research is to determine the throwing distance of the mineral particle from the spreading disc inclined to the horizon. The analytical research has been performed using the methods of modeling, mechanics and mathematics, as well as methods of calculation and computer modeling. In the result of the theoretical research differential equations were obtained describing throwing of the mineral fertiliser particles from the blades and their further distance after leaving the working tool. In the result of calculations new graphical dependences have been obtained of the throwing time from the blades and the distance the particles of different mineral fertilisers can reach, in particular ammonium nitrate, depending on the frequency of the disc rotation, angles of inclination to the horizontal plane, radius of feeding the mineral fertiliser particles, coefficient of friction along the surface of the disc etc. The obatined new analytical expressions and the developed graphical dependences allowed for determination of the working tool parameters that ensure maximal distance of mineral fertiliser particles at centrifugal spreading. The performed experimental investigations proved the correctness of the theoretical research and showed increased throwing distance at the used improved parameters of the new centrifugal working tool.

Abstract:
Based on the analysis of scientific publications and patent sources, it was found that spreaders with vertical spreading shafts demonstrate better technological and operational characteristics compared to devices where the shafts are located horizontally. At the same time, the quality of fertilizer distribution across the field - in particular, the uniformity of application - still does not fully meet modern agrotechnical requirements. In order to increase the uniformity of fertilizer application, a new design of the spreading mechanism is proposed, which includes a set of two-element augers that perform rotational motion with different angular speeds.
