Actually speaking, in last several days farming industry is where agricultural drones are really beginning to take off. Agriculture is on tap to make up 80 percent of the market for unmanned aircrafts in the next couple of decades. With the invention of newer, more effective flight control and flow control technologies, pesticide spraying drones have the potential to launch the agriculture industry into a future of sustainability.
Although drone technology is still modifying production to increase ease of use and lower prices, these agricultural drones already have the potential to go a long way towards improving farmers’ bottom lines – and the environment.
Here are key benefits of drone use in agriculture:
One of the major benefits of drones is their ability to scout farm fields both quickly and efficiently. Rather than having growers evaluate fields manually on foot or by tractor, this technology allows farmers to gain immediate knowledge about the status of their fields in shorter periods of time. This information can be gathered whenever and wherever it is needed, minimizing the response time required addressing issues and maintaining crops.
New drone technology is very effective at collecting data to help farmers improve crop health. Equipped with sensors, drones flying over a field can collect plant height measurements by gathering range information from the plant canopy and the ground below. By measuring near infrared wavelengths through a multispectral sensor, drones can also create vegetation index images, indicating which plants are healthy and absorbing maximum sunlight. Drones also create satellite maps that can help farmers make decisions about fertilizer – a major concern of farmers, as fertilizer represents up to 50 percent of input costs. By using high-tech sensors to absorb near infrared wavelengths, drones make maps that can show where phosphorous and nitrogen might be needed – or where there is an excess of nutrients. In this way, more nutrients are being applied where they are needed most, as more fertilizer is absorbed by plants when it is applied precisely. This level of detail can help farmers increase production and efficiencies that lead to higher yields.

tricken areas. And by increasing water and fertilizer efficiency, agricultural drone technology also helps reduce excess pesticide and fertilizer that runs off into nearby rivers and streams. Less runoff decreases the algal blooms and dead zones in our water systems. Most drones currently available for use in the agriculture industry are very costly. However, with new developments and further innovation, drones may start to prove their value in agriculture.
