Results on the usage of UAV in chemical plant protection

Abstract

he usage of UAV - Unmanned Aircraft Vehicle in the precision agriculture creates numerous opportunities for detecting and informing farm ers about the current state of cultivated crops, and the quality of the imple mentation of certain agro-technical operations during production. In recent years, UAV have been used in chemical plant protection, in the application of mineral fertilizers, in the detection of pests, diseases, and other aspects of ag ricultural production. The importance of the usage of UAV in agricultural production is becoming bigger and more significant, which could, in the long term, affect the more efficient and productive agricultural production, with a significant reduction in the consumption of the inputs of production. This study describes two types of UAV used in the chemical plant protec tion, which were analyzed according to the technical characteristics of the UAV, as well as the precision of the spray coverage of the protective liquid. The precision of distribution of the protective liquid is monitored at differ ent ground speeds and heights during chemical protection. The MG-1 model UAV achieves the best quality of the application of protective liquid at a flight groundspeed of 3 ms-1 (largest effective swath of 6.8 m) and a flying height of 2 m (largest effective swath of 7.3 m). The V6A model UAV achieves the best application quality of the protective liquids at a flight groundspeed of 7 ms-1 (largest effective swath of 5.8 m), and at a flying height of 2 m (largest effective swath of 5.6 m). The results of the UAV analyzed showed that the uniformity of the application of the protective liquid directly de pends on the model of the UAV and its technical characteristics.
