Description: Aerial spraying refers to the application of pesticides or fertilizers from the air using various aerial vehicles, including drones and aircraft. This innovative technique has transformed modern agriculture, allowing for more efficient and precise distribution of agricultural inputs. Drones, equipped with advanced technology, can fly over crops and spray chemicals evenly, reducing waste and minimizing environmental impact. Additionally, aerial spraying allows access to hard-to-reach areas where traditional application methods would be complicated or impossible. The ability to program automatic flights and adjust the amount of product applied according to the specific needs of each plot optimizes resource use and improves crop health. This technique not only saves time and labor but also contributes to more sustainable and efficient agriculture, aligning with current demands for food production and environmental conservation.
History: Aerial spraying has its roots in traditional agriculture, but its modern evolution began in the 1920s with the use of airplanes for pesticide application. However, the use of drones for this task became popular in the last decade, driven by advances in drone technology and the need for more sustainable agricultural practices. In 2015, drones began to be implemented in agriculture in several countries, marking a significant shift in how crops are managed.
Uses: Aerial spraying is primarily used in agriculture for the application of pesticides, herbicides, and fertilizers. It is also employed in reforestation, where drones can disperse seeds in hard-to-reach areas. Additionally, its use is being explored in pest management in crops, as well as in monitoring plant health through the application of specific nutrients.
Examples: A notable example of aerial spraying is the use of drones in precision agriculture in countries like Japan and the United States, where they have been implemented for pesticide application in rice fields. In Brazil, drones have been used for fertilizer dispersion over large soybean crop areas, improving efficiency and reducing environmental impact.
