Picture of Using Agricultural Drone

Abstract

In the abstract provided, it discusses the widespread use of drones in precision agriculture, incorporating technologies like artificial intelligence, sensors, microcontrollers, and the Internet of Things to address challenges faced by farmers. The paper explores various drone applications in precision agriculture, including livestock monitoring, crop spraying, and crop health analysis, highlighting the importance of drones in improving crop performance and environmental quality in the agricultural sector.

Introduction

The introduction section of the text discusses precision agriculture, which involves using technology like drones to improve crop performance and environmental quality by integrating information systems, sensors, and smart machinery. It highlights the significance of drones in agriculture, especially in Malaysia, where precision agriculture can help address issues related to unsustainable farming practices and improve productivity while reducing environmental impact. The text emphasizes the role of drones equipped with various technologies like GPS and sensors in performing tasks such as analyzing plant and soil conditions, mapping agricultural land, and distributing pesticides and fertilizers efficiently.

Commercial agricultural drone

Commercial precision agriculture drones can be categorized into fixed wing and multi-rotor types, with multi-rotor drones further subdivided into single rotor, quadcopter, hexacopter, and octocopter configurations. Fixed wing drones rely on passive lift generated by wings, while multi-rotor drones use motor speed and direction for movement. Multi-rotor drones have limitations in flight speed, distance, and duration due to the power required for lift, as outlined in the comparison of drone types available for precision agriculture tasks such as crop spraying and monitoring.

Crop spraying purpose

Crop spraying using drones is a beneficial method in agriculture for efficiently applying water, fertilizers, and pesticides. Drones can access difficult terrain and reduce human exposure to chemicals, minimizing contamination risks. However, limitations include the drone's flight time and liquid carrying capacity, with spraying systems typically comprising a spray tank, nozzle, and sometimes a pressure pump for pesticide application.

Crop monitoring function

Crop monitoring is crucial for farmers to assess the condition of their crops during growth stages and make informed decisions for optimal yield. Different types of cameras, such as digital, thermal, and multispectral cameras, are used to gather information on crop health and growth. Thermal cameras provide temperature data, digital cameras extract RGB color information, and multispectral cameras capture visible and invisible light to create detailed images for analysis, including indices like NDVI to assess crop conditions.

Mapping and soil monitoring

Mapping and soil analysis involve using aerial mapping data to assess soil conditions and predict crop yields. This process can be done manually or automatically using drones following a predetermined route. Researchers like Wu et al. have developed systems, such as ground-penetrating radar, integrated with drones to map soil moisture levels, providing valuable information for agricultural purposes.

Planting

Seed planting using drones offers a solution to challenges faced by manual labor in terms of time and accessibility, especially in areas with safety risks like rivers and hills. Researchers have developed drones equipped with seed planting mechanisms to automate tasks such as planting, watering, pesticide spraying, and soil monitoring. For example, Nar et al. created an autonomous quadcopter drone that can perform multiple agricultural tasks, showcasing the potential for drones to enhance efficiency and safety in precision agriculture.

Thinking about these technologies

The discussion section in the text likely presents trends in research related to drone applications in precision agriculture, showing an increasing interest in this field over the past few years. It categorizes the applications into those using self-made drones and commercial drones, with quadcopter-type drones being popular for tasks in precision agriculture due to their size, maneuverability, and affordability. The discussion may also touch upon the preference for different types of drones based on specific agricultural tasks, such as hexacopter or octocopter drones for crop spraying and seed planting, and fixed-wing drones for monitoring and mapping due to their flight time and range capabilities.

Conclusion

The conclusion of the paper summarizes the applications of drones in precision agriculture, such as crop spraying, soil analysis, mapping, monitoring, livestock farming, and seed planting. It highlights the importance of government regulations in facilitating drone usage in agriculture and emphasizes the potential for drones to be customized for specific agricultural needs with the right knowledge and technology. The conclusion also notes that while drone applications in precision agriculture are growing, there is still room for further development, especially in rural areas where farmers may not be familiar with this technology.
