In this episode, Keith sits down with Alex Frazier, a fourth-generation farmer and agronomist from South Dakota, who has been interseeding cover crops into his soybeans for six years. Alex shares how planting a simple mix of oats, rye, and flax alongside his beans — then terminating it six to eight weeks later — has helped him boost his farm's soybean average from 39 to 52 bushels per acre while reducing phosphorus inputs by 75% and nitrogen by 40%. They dig into the specifics of mix design, spray timing, weed suppression, nutrient cycling, and the surprising soil test that showed higher organic carbon after interseeded beans than after 200-bushel corn. Whether you're looking to build biology in a corn-and-bean rotation or just want a low-cost, low-risk way to start experimenting with regenerative practices, this conversation is packed with practical takeaways. Tune in and learn how a $13–15/acre companion crop investment can pay dividends for your soil and your bottom line.
