Trent Hamerski (left) explains how he uses his DJI Agras T50 Sprayer Drone to spray crop protection chemicals at Hamerski Farms, Plover. Hamerski used water in this drone demonstration at a Producer-Led Watershed Protection Grant Field Day on August 13. This drone has a 12-gallon tank and can spray approximately 30 acres/hour with high accuracy and excellent crop coverage, greatly reducing the risk of drift or overspray.
