According to Tyler Walker, the sky's the limit when it comes to possibilities of drone utilization in cranberries. He's the manager of Walker Cranberry Company in Cranmoor, Wisconsin. While he used to depend on airplanes and helicopters for all of their insecticide, fungicide, and fertilizer application, he now has transitioned to doing it all by drone. Now in his fifth year of the transition, he says that although there was a learning curve, the cost savings now are evident.
