Agricultural production in Vietnam in recent years has had positive changes, automatic machines and equipment have been applied in many production stages, gradually replacing human labor. Among them, there are unmanned aircraft – Unmanned Aerial Vehicle for short, UAV. As the name implies, the UAV is completely unmanned, controlled remotely by a control device with a radio control application installed. UAV has the function of spraying pesticides, sowing seeds and fertilizers. Using unmanned aircraft is a positive signal contributing to the construction of the country’s agriculture, gradually affirming the application of science and technology 4.0 to agricultural production.
Effective use of drones in agriculture in the world.
In India, startups have created drone planting systems that achieve 75% uptake and 85% reduction in growing costs. These systems shoot pods with seeds and phytonutrients into the soil, providing plants with the nutrients they need to sustain life. The drone can spray precise amount of liquid, adjust the distance from the ground with uniform coverage. Increases efficiency by reducing the amount of chemicals entering groundwater. In fact, experts estimate that aerial spraying can be completed with drones up to five times faster than with traditional machines. (S. Ahirwar et al., 2019)
According to Frank Veroustraete (2015), a drone service start-up in the US has used NDVI maps to orientate crop fertilization on corn and other crops. By using a drone-generated rate of change application (VRA) map to determine the intensity of nutrient uptake in a field, a farmer can apply 300 kg/ha to the area. difficult areas, 200 kg/ha for medium quality areas and 150 kg/ha for healthy areas, reducing fertilizer costs and increasing yields.
The use of drones in agriculture in Japan reached 70% due to the difficult-to-access terrain and the low use of unskilled labor. In the United States, drones are used by agricultural farms for precise management and to increase harvest quality while maintaining or reducing inputs to production. Whereas in Germany, it is used for land management and environmental protection. (Matthias Reger et al., 2018).
Effective application of drones in agriculture in Vietnam
In fact, the area planted to winter rice nationwide this year reached 1,584,6 thousand hectares. (According to the General Statistics Office) and some crops concentrated by region. In the future, agriculture develops with large planting areas but there is a shortage of human resources, so the use of drones is really necessary.
In recent years, the use of unmanned aircraft in Vietnam has initially brought benefits such as:
In Thanh Hoa, in just 20 minutes, the entire 1ha of sugarcane infected with pests was sprayed. According to calculations, each hectare of sugarcane spraying pesticides with drones can save 400,000 VND compared to manual methods. Further testing on sugarcane in Nghe An gave similar results.
In Thai Binh, 200ha of spring rice crop was sprayed with drones, which was assessed as quickly and in time to stamp out epidemics, solve labor problems, avoid harm to people, and help people at the same time. Minh Tan commune saves about 55 million VND for one spray.
In Phu Yen, spraying pesticides on 150ha of rice by drones ensures accuracy for each field as required, while saving time; reducing the cost of hiring spraying services by about 10%, the productivity is expected to increase from 7 to 15%, contributing to improving the efficiency of rice production per unit of production area.
The benefits of applying drone technology to spray pesticides
1. Protecting human health
The use of aircraft spraying pesticides will help people minimize direct contact with drugs, avoid causing toxicity, affecting health, thereby minimizing some dangerous diseases, helping to prolong life. Long service life, save labor.
2. Cost saving
Drones will help save up to 30% of pesticides, thereby reducing drug costs significantly instead of wasting drug like traditional spraying methods.
3. Saving environmental resources
The flexibility in adjusting the smart sprinkler systems will help save 90-95% water, which contributes to effective environmental resource saving, especially with dry fields, anhydrous water sources. rare. With previous manual spraying it seems impossible to do this.
4. Increase crop yield 50 times
One of the reasons why you definitely have to use “Drones” to spray pesticides is that they will help increase crop yields by 50 times. With the vortex spray mechanism, penetrating deep down to the bottom of the tree, trunk, root, and underside of the leaves, it will help eliminate all destructive possibilities of pests and diseases, bringing high economic efficiency.
5. Easy to use, spray a variety of crops, many terrains
