In this episode of the “No-Till Farmer Influencers & Innovators” podcast, brought to you by Calmer Corn Heads, No-Till Farmer editor Frank Lessiter talks with Guy Swanson, who, along with his father, Mort, developed the Yielder drill to no-till a variety of grain, pulse and forage crops while dramatically reducing erosion in the Palouse area of the Pacific Northwest.

“The tires and final drives had been implemented into the drill to give it slope stability, and it would just cruise right around those steep Palouse hills and hold the seed position just perfect …” — Guy Swanson

Join in as Guy and Frank discuss how the Yielder drill was developed and ways in which it changed over the years, fertilizer placement and how it played a big role in its design, and how the CRP led to its eventual decline. They also talk about how the Yielder drill helped build the Denver airport, why Guy advocates long crop rotations, the advantages of no-till, and much more.  

P.S. There’s lots more great no-till stories and history in Frank Lessiter’s new book, From Maverick to Mainstream: A History of No-Till FarmingCheck it out here.
