This week on the Red Dirt Agronomy podcast, the "Doctor's of Dirt, & Everything That Grows From It" talk about the southwest corner of the state—where the cotton fields stretch wide and the water’s been mighty scarce.
Dr. Brian Arnall, Dr. Josh Lofton, and Dave Deken catch up with Maxwell Smith, the IPM specialist working boots-on-the-ground in Altus.
Maxwell breaks down the unique challenges of farming cotton in a region where irrigation depends on the Lake Lugert-Altus canal system—and where just a few inches of water can make or break your season.

They talk through the nuts and bolts of the irrigation setup, why cotton works (when it works), and what’s pushing some farmers to roll the dice on dryland corn.
You’ll also hear why herbicide resistance is bringing back “old-school” weed control, how new cotton trait tech like ThriveOn is changing early-season insect control, and what the future looks like for peanuts in Caddo County.
If you grow cotton, peanuts, or anything under hot skies and dry dirt, this episode's got your name on it.
