Results of development of a software application for calculating the performance indicators of machines for fertilizers application

It has been determined that the volume of global production and consumption of mineral fertilizers continues to grow, while their production resources are limited, which requires improving both technical means for fertilizers application and solving organizational issues of arable farming chemicalization, which ultimately will allow for high-quality distribution of fertilizers over the field surface within optimal agrotechnical terms. The tasks can be solved by increasing the accuracy of tools for calculating the basic performance indicators of machines for fertilizers application, which became possible due to development of electronic cartographic services and specialized tools for assembling machine and tractor units. The reserve for increasing the performance of arable farming chemicalization machines is also the determination of their rational design parameters depending on specific production conditions, such as the length of the run, contour of the fields, specifics of the organization of fertilizer application, the distance from the fertilizer warehouse to the work site and local logistics. In this regard, an analytical dependence is proposed to determine the functional relationship of performance with the main design parameters of the fertilizer spreader, which is an additional criterion for choosing a rational combination of machine and tractor units for fertilization, taking into account specific production conditions. An algorithm has been developed that is implemented in a software application for calculating the performance indicators of machines for fertilizers application.
