GARNER, Iowa — Drones have been part of agriculture's tool box for years, especially in increasing efficiency and effectiveness for crop acres. A north Iowa field day will focus on how one farmer uses drone technology for pinpoint weed control in pastureland not easily accessible by other methods.

The pasture management field day is set for Sept. 21 at Lynn Kluver’s pasture southeast of Crystal Lake. Russ Euken, beef and swine specialist with Iowa State University Extension and Outreach, said a drone demonstration will show attendees how a drone can be used for weed control in areas that are not easily accessible for ground equipment or larger aircraft.

Gentry Sorenson, field agronomist with ISU Extension and Outreach, will discuss general pasture weed control methods, and Kluver and Adam Stenberg (droner operator) will discuss their experience using drone-applied herbicide for weed control in the pasture.

The field day agenda also includes basic grazing management along with tips on fall pasture care, forage and feed management for fall and winter, and resources available. T.J. Herrick, wildlife biologist with the Iowa Department of Natural Resources, will join the team for a discussion of opportunities to graze wildlife management areas.

The field day begins at 1 p.m. on Sept. 21 at the pasture located southeast of Crystal Lake. The address is 1115 310th St., also known as County Highway B16 Britt. There's no cost to attend and no preregistration is necessary. See the event flyer.
