Phytosanitary treatment by drone

Our friend Luis Alcázar, from the company Pulveriza Dron, offered us to visit him at his work with the DJI Agras T30 drone. It was the first time we saw an agricultural drone working. The morning was very interesting as we were able to learn about the working process of the device... but let's take it step by step. 

First of all, before making the flight, it is necessary to setting the program the flight so that the work is almost automatic. To do this, you have to geolocate the field and configure the working width as well as different parameters according to the work to be done, the type of crop, etc. Once the drone is ready to fly, it should be noted that the batteries last about 6 minutes and therefore that will be the time to empty the 30 litre tank the drone carries (there is also a tank for solids which is similar to a small fertiliser spreader). It is important to have several batteries and a generator that recharges them in order to be able to work a full day. 

Secondly, the plant protection product to be used in the treatment must be prepared. This product is usually mainly active material, but water is also used to make a correct mixture. This mixing is usually done in an auxiliary tank of 500 litres and one of the operators oversees supplying the liquid while the other changes the batteries... two people usually work with the drone: pilot and handler of phytosanitary products. 

Finally, our impression was that it is a tool to be taken into account for crops or situations where you cannot enter with the tractor or Unimog (high crops, muddy or waterlogged areas, etc.), it is a perfect solution. In addition, in high-yield crops (irrigated cereals, etc.), it is an advantage as it does not damage any part of the field (tractor ruts) and therefore you have more yields, the crop is uniform in its entirety and harvesting task is easier.
