Modern technologies in the agricultural sector present tremendous opportunities to increased farm profitability and productivity. To achieve this, it is necessary to identify suitable solutions and ways to meet agricultural needs and requirements. This may be done by increasing production and finding rapid solutions for common issues that arise in production and have an impact on the agricultural economy. Drone usage for precision agriculture has grown dramatically in the recent years. Since drones can collect data specific to a certain site and assess crop health, they are helpful in precision agriculture. Drone technology helps in preserving soil fertility, reduces overuse of water and pesticides and herbicides, increases productivity and enhances quality, while also assisting in the efficient use of human labour. Aerial seeding and spraying are two uses of drone technology that can help to overcome manpower and cost constraints associated with manual labour. Even though there are some constraints of using drones, drone market will grow as their new applications are realized. This paper provides an extensive overview of the types, construction and applications of drones in agriculture. It also points out the potential advantages of drones in this field and calls for cooperation to overcome obstacles and realize the full potential of precision farming on a worldwide scale.
