 I'm Nicole Haslip with Ag Headline News on Brownfield. A Purdue University agronomist is working on advancing aerial drone spraying technology on corn and soybeans. Darcy Talenko tells Brownfield it's the second year for trials. The ground equipment couldn't get in on that first spray day. We had to wait a couple days for the field to dry out. And so that's where the drones and airplanes have an advantage.
