This is the most important part for drone applications in crop management. With multispectral imaging and RTK it's possible to get much more specific about application of various products that were previously applied in bulk to prevent or remedy a situation.
Unfortunately TFA amounts to an advertisement and doesn't have any useful info.
And if you remembered where you sprayed it, you can sell a part of your crop at a premium, i.e. as "insecticide-free".
An acre of cash crop is has gross value of $500-700.
Targeted application by drone makes it a) actually work at all under stricter regulations and b) can be placed only on the areas that need it, so it actually is cost competitive with blanket application despite being more expensive per acre.
That said, in ten years this will probably be all drones. The ability to do precision dosing, safely fly a few feet above the target, lower noise, lower capital investment, no need for commercial pilot, little to no overspray, high automation potential, simultaneous high resolution monitoring, etc etc etc.
Big limitation now are the meager payloads and flight times. Drone delivery is going to open up the market for manufacturers to start pumping out drones that meet that demand and it’s going to be mothballs for the old guard in quite a few places.
Hopefully companies like Air Tractor get on board and adapt their product lines, they have way too much valuable experience.
I would have thought they would have to be fuel based.
I would have thought electric for information (ie photography) Fuel for the meat world.
The Chinese are electric as well - https://www.xa.com/en/xp2020
I don't get it?
