Development of unmanned aircraft complex for application of plant protection means and fertilizers

Currently, unmanned aerial systems (UAS) are used everywhere, including in agriculture in conjunction with other precision farming systems. The traditional method of applying liquid preparations to the soil from ground equipment has a number of disadvantages due to the impossibility of working after rain, the destruction of 4 to 8% of crops in the field, and the difficulty of working in a field with an incorrect configuration. These shortcomings in the use of ground technology are fundamental and cannot be eliminated. UAVs are deprived of these shortcomings, due to the fact that they are widely used in agriculture and are a promising direction in the development of precision farming, both for monitoring the state of crops and their processing, and for the contribution of fertilizer application. However, the prospective review showed that the UAV application has a number of disadvantages, such as detection by flight time, battery discharge detection, small capacity of the drug tank, which leads to multiple refueling. This paper presents the justification and development of an unmanned aerial complex for the application of plant protection products and fertilizers, which ensures an increase in the efficiency of the use of energy, material and labor resources through the use of self-organizing UAV technology.
