Agriculture plays a vital role in economic development and global food security, yet traditional methods of fertilizer and pesticide application remain labor-intensive, time-consuming, and often result in uneven chemical distribution and environmental harm. The proposed AgriDrone: Automated Fertilizer and Pesticide Distribution System introduces an unmanned aerial vehicle (UAV)-based solution designed to enhance precision farming through automated and controlled agrochemical spraying. The system integrates GPS-based navigation, programmable flight control, and a precision dispensing mechanism to ensure uniform coverage across agricultural fields while minimizing chemical wastage. Equipped with sensors for monitoring field conditions and crop density, the drone can optimize spray patterns and intensity in real time, thereby improving efficiency and reducing operational costs. By eliminating direct human involvement in chemical spraying, the system also minimizes health risks to farmers. Experimental evaluation indicates that the AgriDrone system achieves faster coverage, improved uniformity, and reduced input usage compared to conventional manual methods. Overall, the proposed system offers a cost-effective, scalable, and environmentally sustainable solution that supports modern precision agriculture and enhances crop productivity.
