Precision agriculture is rapidly evolving through the integration of Unmanned Aerial Systems (UAS), commonly known as drones. This paper presents the design and functional analysis of an agricultural drone system specifically optimized for nutrient spraying, primarily focusing on its innovative nozzle technology. The research investigates how precise control over droplet size, achieved through a specialized nozzle design, enhances nutrient delivery efficacy. Experimental trials targeting a 100–300 micron droplet size demonstrated efficient nutrient absorption via plant stomata, leading to significant reductions in water (up to 95% less compared to manual methods) and chemical inputs. Furthermore, preliminary results indicate potential crop yield increases of 15–20%. This study underscores the critical role of advanced nozzle systems in maximizing the efficiency and sustainability of drone-based nutrient applications in diverse agricultural settings globally.

摘要

Precision agriculture is rapidly evolving through the integration of Unmanned Aerial Systems (UAS), commonly known as drones. This paper presents the design and functional analysis of an agricultural drone system specifically optimized for nutrient spraying, primarily focusing on its innovative nozzle technology. The research investigates how precise control over droplet size, achieved through a specialized nozzle design, enhances nutrient delivery efficacy. Experimental trials targeting a 100–300 micron droplet size demonstrated efficient nutrient absorption via plant stomata, leading to significant reductions in water (up to 95% less compared to manual methods) and chemical inputs. Furthermore, preliminary results indicate potential crop yield increases of 15–20%. This study underscores the critical role of advanced nozzle systems in maximizing the efficiency and sustainability of drone-based nutrient applications in diverse agricultural settings globally.
