Special Issue Information

Dear Colleagues

An aging population and rapid urbanization are exacerbating labor shortages in agricultural production, resulting in higher labor costs. Owing to the development of sensors and intelligent control technology, unmanned and manpower-saving aerial application equipment and technology are being iteratively upgraded to promote efficient and intelligent agricultural production. The spraying of aerial chemicals was the first aerial application technology used in agricultural production, and it is widely used in the control of large-scale and sudden diseases and pests. It is worth noting that, in China, the number of UAV sprayers employed has rapidly reached more than 100,000 as of 2021, representing a 15-fold increase over a 5-year period. Nowadays, the application domain of aerial application technology is subdivided, and it is expanding to many new application scenarios (e.g., fertilization, seeding, pollination, detasseling, and feed delivery), exhibiting great potential in agricultural production.

It should not be ignored that the performance of aerial application technology needs to be improved due to factors such as the distance between the aircraft and the target, downwash flow, etc. The mechanism implicated in the delivery of agricultural materials and movement outside/inside the crop canopy remains unclear. In addition, dedicated precision actuators, advanced systems and equipment need to be developed.

This Special Issue focuses on in-depth research addressing novel aerial application technologies and equipment for agricultural production, including remote sensing, aircraft path planning and navigation, experimental and numerical models for the movement of agricultural materials, collaboration between UAVs and UGVs, accurate application control methods and the evaluation of the application quality; this is in order to enhance the performance of aerial application so as to achieve a high and stable application quality. Research articles will cover a broad range of aerial applications for agricultural production, including chemical spraying, fertilization, seeding, pollination, and detasseling, etc. All types of articles, such as original research, opinions, and reviews, are welcome.

(1) Background: Various types of adjuvants are added during application to enhance the spraying effect, but most adjuvant formulations are proprietary products, and their exact compositions have not been disclosed. (2) Methods: The spatial distributions of droplet sizes and velocities generated by the atomization of different polymer adjuvants were measured based on the phase Doppler interferometer (PDI) measurement method. The sub-area statistical method was used to quantitatively analyze the droplet characteristics at various points below the nozzle. (3) Results: The polymer (polyethylene oxide (PEO))/associative surfactant (sodium dodecyl sulfate (SDS)) can increase the droplet size and velocity of the solution after atomization by increasing the amount of the polymer/associative surfactant to reduce the equilibrium surface tension of the solution and increase the viscosity. Different concentrations of polymer/associative surfactant atomization produced larger droplet sizes and better uniformity than polymer/non-associative surfactant (polysorbate-20 (Tween20)). At the same position, the relationship between droplet velocities for the three adjuvant combinations was roughly as follows: PEO/SDS solution had the highest velocity, followed by PEO solution, and PEO/Tween20 solution had the lowest velocity. (4) Conclusions: The optimal of droplet size distribution can be achieved by adding appropriate amounts of associative surfactants to polymers. Full article
