Using Drones and iPads to Improve Farms

A new 3-pound drone controlled by an iPad is helping one farmer identify problem spots in his fields so he can fix them before the season starts. Jeffrey Graybill bought the $300 device and has been using it constantly. He says that once corn gets high that it`s very difficult to find problem spots on the ground, but the drone, which can fly up to 400 feet, makes this process much easier.
