Abstract:As an effective supplement to ground machinery, UAVs play an important role in agriculture and have become indispensable intelligent equipment in the development of precision agriculture. Various types of agricultural UAV-based spreading devices, mainly disc-type and pneumatic-type, have appeared in domestic and foreign markets. UAV-based rice topdressing has gradually become a widely recognized application with great market potential. In the process of UAV-based low-altitude fertilization, due to the existenc… Show more
“…Fluid flow, spray uniformity, and working width control. As shown in [7,11,35], these parameters are controlled by the flight speed and altitude of the UAV. In [11], it is shown that by varying the UAV flight speed in the range of 10 to 50 km/h and the flight altitude from 1 to 5 m, it is possible to control the fluid flow from 1 to 5 L/min.…”

“…By analyzing Table 9, it is evident that the thickness of the film containing the PPA can be adjusted by increasing the speed and altitude of the UAV. This relationship is explained in [35], where the opening of the spray cone changes in response to increasing speed or altitude, which ultimately changes the coating surface and subsequently the film thickness. The accuracy of the data presented in Tables 8 and 9, and therefore the conclusions drawn, are supported by field experiments [11,72].…”

“…A variety of geographic, regulatory [30], and other factors [31][32][33] influence the use of UAVs. At the same time, the introduction of UAVs in agriculture should be accompanied by a thorough analysis of the technical and theoretical aspects of agricultural technology [34][35][36][37], taking into account both the degree of implementation and the areas of application [38][39][40]. The importance of these studies for Russia arises from the elimination of technical services and training farms in agricultural research institutes, similar to the American Extension Service, during perestroika.…”
This review article examines the potential for intensifying Russian crop production through digital transformation, particularly through the use of unmanned aerial vehicles (UAVs). (1) The importance of this topic is driven by declining food security in some parts of the world and the Russian government’s goal to increase grain exports by 2050. (2) Comparisons of agriculture technologies suggest that the use of UAVs for crop treatment with agrochemicals is economically effective in certain cases. (3) Specifically, UAV treatment is advantageous for plots with irregular shapes, larger than 2 ha, and containing between 9 and 19% infertile land. It is also important to agree on the flight parameters of the UAV, such as speed and altitude, as well as the type of on-board sprayer and agrochemical. In case of insufficient funds or expertise, it is recommended to hire specialized companies. (4) The listed peculiarities of Russian crop production led to assumptions about the regions where the use of UAVs for agrochemical treatment of crops would be economically effective.

“…In a similar vein, Faiçal et al [12] integrated ground sensors with UAV spraying, dynamically adjusting flight parameters based on measured environ mental parameters to achieve more uniform pesticide spraying. Song et al [13] optimized the distribution of fertilizer particle deposition under different flight altitudes and speeds of multi-rotor UAVs during fertilization, ensuring a reasonable and effective deposition amount during actual fertilization processes. Furthermore, Gu et al [14] explored the in fluence of different flight parameters on point cloud data quality, revealing a positive cor relation between the root mean square error of the airborne lidar flight trajectory and fligh altitude and speed.…”
With the growing prominence of UAV-based low-altitude remote sensing in agriculture, the acquisition and processing of high-quality UAV remote sensing images is paramount. The purpose of this study is to investigate the impact of various parameter settings on image quality and optimize these parameters for UAV operations to enhance efficiency and image quality. The study examined the effects of three parameter settings (exposure time, flight altitudes and forward overlap (OF)) on image quality and assessed images obtained under various conditions using signal-to-noise ratio (SNR) and BRISQUE algorithms. The results indicate that the setting of exposure time during UAV image acquisition directly affects image quality, with shorter exposure times resulting in lower SNR. The optimal exposure times for the RGB and MS cameras have been determined as 0.8 ms to 1.1 ms and 4 ms to 16 ms, respectively. Additionally, the best image quality is observed at flight altitudes between 15 and 35 m. The setting of UAV OF complements exposure time and flight altitude; to ensure the completeness of image acquisition, it is suggested that the flight OF is set to approximately 75% at a flight altitude of 25 m. Finally, the proposed image redundancy removal method has been demonstrated as a feasible approach for reducing image mosaicking time (by 84%) and enhancing the quality of stitched images (by 14%). This research has the potential to reduce flight costs, improve image quality, and significantly enhance agricultural production efficiency.
“…They can perform tasks such as soil analysis [30][31][32], seedling density tracking [33,34], weed and pest detection and classification [35][36][37][38], yield prediction [39][40][41], and harvest readiness assessment. In some rare cases, UAVs can be used for harvesting, precision fertilization [42][43][44], pesticide injections [45][46][47], or even mechanical pest destruction. The Internet of Things and sensors provide farmers with real-time information on soil parameters, temperature, gases in the air, weather conditions, and many other parameters, which are often passed to cloud infrastructures and can then be used for analysis and prediction [48][49][50][51].…”
According to the Food and Agriculture Organization, the world’s food production needs to increase by 70 percent by 2050 to feed the growing population. However, the EU agricultural workforce has declined by 35% over the last decade, and 54% of agriculture companies have cited a shortage of staff as their main challenge. These factors, among others, have led to an increased interest in advanced technologies in agriculture, such as IoT, sensors, robots, unmanned aerial vehicles (UAVs), digitalization, and artificial intelligence (AI). Artificial intelligence and machine learning have proven valuable for many agriculture tasks, including problem detection, crop health monitoring, yield prediction, price forecasting, yield mapping, pesticide, and fertilizer usage optimization. In this scoping mini review, scientific achievements regarding the main directions of agricultural technologies will be explored. Successful commercial companies, both in the Russian and international markets, that have effectively applied these technologies will be highlighted. Additionally, a concise overview of various AI approaches will be presented, and our firsthand experience in this field will be shared.
