Drones have drastically improved agricultural efficiency, both in terms of cost and labor. They’re spraying crops with pesticides and herbicides, better targeting where exactly those chemicals go to improve plant health while protecting the environment (and saving money).  They’re being outfitted with sensors to analyze plant health, water levels and more. And often, those sensors are so compact they can be outfitted to consumer drones like the DJI Phantom or even a DJI Mavic. And as imaging sensors get smaller and more efficient the cost-benefit of this technology will continue to grow. 

Depending on your agricultural use-case, there’s probably a drone that can do it, and a drone for every budget.

The best drone for spraying: DJI’s AGRAS MG-1S

This ~$15,000 drone is an octocopter (it has eight motors, arms and propellers), designed to carry 10kg of fluid to assist in pesticide and herbicide delivery. It can cover 10 acres (4 hectares) in a single flight, which DJI says is 60 times faster than manual spraying.

The drone has four nozzles located…
