RegenPGC is a research project, for sure, but we are more than that. We want to make sure that our work is accessible beyond academia. Iowa State University, our primary home, is a land-grant university. In fact, Iowa was the first state to take on the challenge of creating a land-grant institution under the provisions of the Morrill Act of 1862, and on March 29, 1864, Iowa State was designated as the first US land-grant institution.
As a land-grant university, Iowa State University is focused on continuing to promote the foundational land-grant principles of education, research, and public service. That’s why our research team produces fact sheets like this one, Environmental constraints, spring suppression, and perennial ground cover systems: a 25-year analysis of spreadable hours for glufosinate, sawlufenacil, and paraquat across the U.S. cornbelt (https://www.regenpgc.org/wp-content/uploads/2026/06/fact_sheet_revised_June19.pdf).
This fact sheet provides information to help understand the challenges behind adopting perennial groundcover in the US Midwest since: “A key management challenge in PGC systems is balancing the benefits of the perennial groundcover with the need to produce a productive corn or soybean cash crop. Consequently, early-season suppression is often necessary to reduce competition between groundcover and emerging crops.” Check it out and grow your knowledge!
