Insufficient amount of fertilizer applied during the main tillage highlights the top dressing of fertilizer solutions. The main advantage of foliar application is the quick delivery of nutrients by absorbing them through leaves and other parts of plants. High efficiency of foliar application is achieved by increasing the coverage of the plant leaf area. A new generation of machine resource-saving fertilizer application technologies will increase the efficiency. One of the promising technologies is electrostatic spraying of crops. It will reduce the consumption of micronutrient fertilizers, optimize the size of the deposited drops, and increase the amount of fertilizer drops applied to the leaves. Electrostatic spraying provides good surface coverage. It allows to use a process automation system and increase productivity and efficiency. The essence of the electrostatic method consists in spraying a working solution with the transmission of an electric charge to the aerosol particles. Charged aerosol particles are uniformly deposited on an oppositely charged surface. In industry, this method has found great practical application. The use of this method in agriculture is difficult due to a number of problems. One of the problems is working with biological objects. Therefore, when developing devices for electrostatic charging of aerosols, this problem must be taken into account. The proposed method for charging aerosols can eliminate the influence of the device on biological objects and increase the electrical safety of the system. For effective operation of the device, it is necessary to experimentally determine the parameters of work when spraying plants.
