Application of unmanned aircraft (UAV, Drone) in agriculture from A to Z

Drones in agriculture

Drones can be used to optimize farms based on large amounts of visual data on the condition of crops, fields and livestock, as well as applying pesticide spray.

Spectral Scanning PlaneAcceptance of drones being used as an important part of farm equipment is driven by:

  • Average farm size for 2017 is 180ha really just need time to monitor and check
  • Highly accurate images of crops can help determine wilting and growth due to the advent of low-cost multispectral cameras that can capture visible light (VIS) and light. Near infrared (NIR) light is reflected by plants.
  • Farmers can use this data to integrate into smart irrigation systems as well as manage pesticides

Overview of agricultural drones.

4 main applications of drones in agricultureBenefits of drones in agriculture

Drones are an affordable investment when compared to most farm equipment. They can pay for themselves with their own savings in a single crop. By collecting accurate field data, you can:

  • Get data with much higher resolution (up to 16x compared to traditional satellite methods) about every happening in the field
  • Early detection of areas that lack irrigation, wilted plants, pests or water leaks anywhere.
  • Get a real amount of plant growth so you can buy insurance, plan labor and predict output
  • Get a true count of plant growth so you can purchase insurance, plan labor schedules and predict yields

Hard-wing aircraft
Fixed wing aircraft

Classification of Drones: propeller vs hard wing

Propeller-based drones are by far the most popular type of agricultural UAV because of their ease of use, cost, and versatility. That is not to say that the fixed-wing drone does not have its outstanding features.

The plane can be controlled manually, but nowadays, most people use software to control the flight automatically, it can fly according to a predetermined route according to each flight path in the farm.


  • Take a photo
  • Video
  • Multi-spectral scanning: Identify nutrient deficiencies, pest damage, fertilizer needs and water quality.
  • Super spectroscopy: Used to analyze plant nutrients, plant diseases, water quality, and surface and mineral chemical composition.
  • Lidar (a detection system that works on the principle of radar, but uses light from a laser): Using a laser, this sensor generates elevation data that can create a 3D model of your farm.
    Thermal sensor: Monitors the surface temperature of soil and plants

By combining these sensors, it is possible to produce an accurate GPS 3D model of your farm and data that cannot be collected by the human eye.

Some terms you may hear are: Normalized Difference Vegetation Index (NDVI) and Normalized Difference Red Edge (NDRE). NDVI is basically a measure of plant health based on how plants reflect light at specific frequencies. Healthy plants reflect large amounts of near-infrared (NIR) light where unhealthy plants absorb more.

Software to control drone spraying application

Software to control drones:

Drone software will first allow you to map the farm and create flight paths. Once you’ve flown your route, you then need software to help determine what’s really happening off the farm over time, determine what actions to take, and send that data to the user. and your devices on the ground.

Aircraft type and cost

You might consider investing in the aircraft yourself or hiring a service company to do the flying and surveying missions.

The cost of buying a spray plane: The cost usually ranges from about 50 million to 600 million (price in the US, not including the cost of importing to Vietnam)

Flight regulations: You may need a license or certificate to allow you to fly a drone. Refer to the article: unmanned aircraft management

Next generation

  • Automatic docking with a charging station between flights
  • Integrating drones with pesticide spraying applications
