Agricultural aircraft are specialized planes or helicopters designed for farming purposes. They are primarily used for tasks such as crop dusting, which involves spraying pesticides or fertilizers over fields to protect and nourish crops. These aircraft can cover large areas quickly, making them efficient for farmers. In addition to crop dusting, agricultural aircraft can also be used for aerial seeding, where seeds are distributed over fields from the air. This method can help in planting crops in hard-to-reach areas. Overall, these aircraft play a vital role in modern agriculture, enhancing productivity and efficiency.
