There are many drone applications in agriculture for yield estimates, detecting vegetation stress due to lack of water or disease infection, spraying and dusting, monitoring and classification, and many other applications.
There are several systems developed to perform such jobs worldwide. Also, anybody with minimum facilities can research and perform experiments to develop such systems that are particularly adapted to local needs.

Drones can assist in precision agriculture by performing variety of agricultural tasks including soil health monitoring, seed planting, fertilizer application, crop stress management, irrigation schedule planning, weed management, crop yield management, and weather analysis. Agri-drones can be used to spray chemicals as they have reservoirs, which can be filled with fertilizers and pesticides for spraying on crops in very little time, as compared to traditional methods. Drones can be used for assessing the health of any vegetation or crop, field areas inflicted by weeds, infections and pests and based on this assessment, the exact amounts of chemicals needed to fight these infestations can be applied thereby optimizing the overall cost for the farmer. Fixed-wing drones are commonly used in agriculture for mapping fields, monitoring crops, and identifying potential issues such as pests or irrigation problems. They are also used for surveying, mapping, and aerial photography. Drones can cover large areas of land quickly and efficiently, allowing farmers to gather data and monitor crops more effectively. This can help to identify issues early, leading to faster and more effective interventions. Drones can be used for assessing the health of any vegetation or crop, field areas inflicted by weeds, infections and pests and based on this assessment, the exact amounts of chemicals needed to fight these infestations can be applied thereby optimizing the overall cost for the farmer. The drone can capture the soil moisture stress condition and excess water at particular area in the agriculture field. The field survey conducted using drone helps in achieving the water use efficiency and identification of leaks in irrigation through frequent irrigation monitoring. Drone monitoring systems help the farmers for observing the aerial views of the harvest. This gives information related to the water system, soil variety, pests, and fungal infestations. Drone Technology uses and applications. Drone technologies hold great importance in many fields. Areas like construction, defense, Aerial photography, marketing, delivery, Agriculture, rescue, entertainment holds many Real Time applications of drones.Drone technology has the potential not only to boost agricultural productivity but also to support climate-smart agriculture by facilitating better resource management and adaptation to climate change. Modern drones or UAVs are capable of covering at least 1,000 hectares of land every day. They are equipped with smart technologies, high-resolution cameras, and high-tech sensors to procure precise data about crop water requirements and irrigated areas. Agriculture drones are being used to map out land and acquire data such as elevation, topography, and soil composition. This data can then be used to select optimal planting areas and irrigation patterns. By 2025, India is forecasted to be the world's third-largest drone market. The Government of India is planning to make India a Global Drone Hub by 2030, and expects total turnover of the drone manufacturing industry to increase from ₹ 60-80 crore to ₹ 900 crore by FY 2024.The integration of artificial intelligence (AI) and machine learning in drone technology is one of the most significant trends to watch. This development will enable drones to perform complex tasks with minimal human intervention, opening up a world of possibilities in various industries. The Union Ministry of Civil Aviation estimated that the industry, which now has a turnover of around INR 80 crore, will reach INR 12,000-15,000 crore by 2026. The global commercial drone market was valued at $6.51 billion in 2021, and it is expected to grow to $47.38 billion by 2028 at a CAGR of 28.58%. Drones can be used for monitoring the conditions of crops throughout the crop season so that the need-based and timely action can be taken. The quick and appropriate action can prevent yield loss. This technology will eliminate the need to visually inspecting the crops by the farmers.
