Relay Cropping Grain with Jason Mauck

Relay Cropping Grain with Jason Mauck

Feb 24, 2020


In this episode of The Regenerative Agriculture Podcast, John interviews Jason Mauck, an Indiana corn, soybean, wheat, and hog producer who thinks outside the borders of convention and who has pioneered a number of innovative practices.

Jason describes the guiding force behind his experiments and innovation as the desire to gain as much control over the variables in farming as possible. Rather than embracing traditional planting and application methods, Jason experiments with new approaches to farming, measuring whether they give him more resilience and control over his inputs and yields.

Jason is passionate about relay cropping, the practice of having a second crop growing before the first crop is harvested. An example of this is a cool grass cereal such as wheat or rye planted with a summer annual of corn or soybeans. He describes his experimentation with this approach, from the original plan of planting two crops together and doing all of the same things he would do for each crop planted separately, to his current understanding of the equilibrium needed to successfully bring both crops to maturity with a productive harvest. He has experimented with modifying the width of the rows to accommodate the needs of both growing crops. He also discusses the role manure management plays in his farming operation, and how his goal is to use this source of nitrogen to decrease his dependence on off-farm inputs.

In this interview, Jason talks about seldom discussed ideas, such as the phi angle of plant expression, which he describes as coordinating plantings so the solar angles reach the intercropped species. Also, he describes how a farmer can influence 6-ear corn or 200-seed wheat by following the principles of the Golden Mean. Jason talks about the conventional rationale of farmers, by which seed is planted with high hopes, given plenty of nitrogen and all the “by-the-book” fungicide and herbicide applications, and how his approach differs. Alternatively, he thinks of maximizing his yield with on-farm inputs and minimal costs, as well as considering the benefits of water absorption and soil biology the planting adds to the ecosystem.

Jason also talks at length about farm economics, and how to increase the contribution margin by decreasing the input costs while employing methods to increase yields. Listen to this episode to hear from one of the most innovative young farming voices in the United States, and follow his social media channels below to keep up with his stream of ideas and measured experiments.
