Sell your tractors and buy drones! So recently i ventured into use of drones in perfoming large scale field spraying operations against fall army worms (a very dangerous pest that can finish your entire field in hours). The experience was amazing, These small birds spray at alarmingly high speeds of upto 50km/hr ofcourse depending on the prevailing weather conditions. Moreover, they guarante an efficiency of upto 95% with regards to effective chemical use and application. Amizingly, they can work perfectly at night, as long as the pilot is willing to be available for a nights shift haha! Thats not all, its operation is as simple as flying any other toy drones (sic). Watch it here in Action What more! Sell you tractors and heavy farm implements and replace them with drones.
