One of the most important resources for farmers interested in sustainable practices is a soil test commonly known as the Haney Test. In this episode, we talk to the developer of the test, Rick Haney, a soil scientist who will retire from USDA Agricultural Research Service on June 30. Rick tells Field Work producer Annie Baxter how he came up with his legendary soil health test — and exactly how it works. We also hear from Indiana farmer Rick Clark about how he converted his 7,000-acre farm from conventional corn and soybean to no-till and diversified his crops. The Haney test played a crucial role.  The two Ricks help lead a brainstorm about scaling up regenerative practices to slow climate change and help farmers be more profitable — with Iowa farmer Brian Hora (Mitchell’s dad), North Carolina farmer Russell Hedrick and Great Plains Regeneration Executive Director Jessica Gnad also joining in.  Our show was recorded at Field Work co-host Mitchell Hora’s field day June 3, 2021, in Washington County, Iowa.
