Why drones?


Why drones? What is causing such an increase in drones? In a time where technology is everything, it would only make sense for drones to be the new fad. The biggest question is what can they do for agriculture?

Drones and agriculture go together like peanut butter and jelly. It makes sense to use them to make the farmer and ranchers lives easier. How? There are several applications that can help make life on the farm a little easier.

First some background on drones. Drones are also known as UAV, which stands for an unmanned aerial vehicle. This means that they are flown by someone through a receiver on the ground. Did you know that the first flight of an unmanned aerial combat vehicle was in the early 1910s for the military? They started to focus more on UAV’s at that time to help with target training.

There are several types of drones as well. With all different types of drones out there, how are you supposed to know which one would work for your operation? That is a great question! Every operation is different and your needs with a drone with vary. Depending on the drone you pick you have to decide what you are going to use it for down the road. Will you be using it to check your cattle? What about flying across your fields to see your crop index? Those are questions you need to ask when you are shopping around.

DCIM100MEDIADJI_0003.JPGI have seen application of a larger drone by Slant Range with a NDVI sensor. NDVI stands for Normalized Difference Vegetation Index. A NDVI sensor can measure the solar radiation that the plants put back out after absorbing it to carry out the process of photosynthesis. The sensor is finding the near-infrared light that the plants are putting off from its leaves. By using a NDVI sensor you can measure the plant productivity, how much rainfall may have occurred, weedy areas that may be in the field, and other applications. Infrared in the NDVI also can measure the amount of heat being put off. Using this application of NDVI, you can fly over your cattle herd and see if any of them may have a higher temperature than normal. You can also use the regular camera to fly over your herd to see if there are any changes occurring in the herd.

While attending Southeast Community College in Beatrice, NE, I have had the opportunity to learn some about drones. I have been able to apply the information I gathered from the drone, to the fields on campus and create prescriptions and suggestions. The drone I have been able to fly the most is the DJI Phantom 4. The students on campus have been able to fly over most of the land on campus and see what it looks like from above. We tested out the DJI app that you download to fly the drone and used some of the features.

With some of those applications and different drones in mind, you can narrow down what may work for your operation.
