There are several advantages to using drones for cranberries. First the alternatives include helicopters, ground-rigs, and backpack spraying. Helicopters are environmentally nasty for small farms, ground rigs crush the crops and backpacks are unhealthy and hard work. When the copter leaves the growers are blowing the fertilizer from their cars and driveways. Order 100 pounde per acre and perhaps get 80 pounds on the crop. Next is precision. drones are flying at 10' and getting into the nooks and crannies of odd shaped cranberry bogs. Better coverage with less product. Drones can apply fertilizer at night - in the dark. Yes we need lights on the drone but the drone isn't looking its just flying its programmed route. Then there ar the no-fly and no-spray sections of a farm. Rather than leave it to the pilot of a plane or copter, the obsticals and no fly zones are programmed - so lets do it at night when the wind is dead. I going to try this week.
