New research informs how corn and perennial groundcover can coexist

Amina Moro in the lab

Today, we honor RegenPGC Graduate Education Community member Amina Moro and her work on corn’s “Shade Avoidance Response.” Iowa State University – College of Agriculture and Life Sciences recognized Amina’s work by featuring her in the article, “New research shows finding the ‘sweet spot’ is key to successful groundcover systems.” See: https://www.cals.iastate.edu/news/2026/new-research-shows-finding-sweet-spot-key-successful-groundcover-systems

Amina’s work informs how corn behaves when perennial groundcover is located in proximity to it. As the article specifies, “The practical applications of this research are clear. By maintaining a small buffer zone – around 25 centimeters – farmers can prevent early stress signals in corn while still benefiting from soil protection.”

According to Amina, “Farmers do not have to choose between improving soil health and maintaining yield,” Moro said. “With the right combination of spacing, hybrid selection, and management practices, it is possible to design systems where corn grows efficiently while the soil remains protected.”

Learn more about the science behind Amina’s work in her recently published paper in the Journal of Agronomy, “Spatial Proximity to Perennial Groundcover Triggers Shade Avoidance Responses in Corn” (https://www.mdpi.com/2073-4395/16/7/729).

New ideas needed? Find them at RegenPGC!

It’s spring! It’s always a good time to be open to new ideas on managing our land and soil in row crop production. Our @RegenPGC Perennial Groundcover Project does precisely that. We are working on new approaches to a lot of old issues, such as how to:
◼ Reduce soil erosion (reduced P losses)
◼ Reduce water runoff
◼ Increase water infiltration
◼ Improve soil quality
AND
◼ How to achieve greater stover harvest

Our Project Director, Dr. Raj Raman, has some ideas on these topics, which he covers in this video presentation, “Perennial Groundcovers in Corn & Soybean Production Systems: Potential & Scalability.” You can find the video at https://youtu.be/MYQcSBZXVXQ  and the accompanying Field Notes at https://iastate.box.com/s/fij94zkojl6kpaofkmepdk66cpzb0ij3.

New RegenPGC Video Series

We realize some of you may be new to perennial groundcover and its potential for modern #agrictulture. So, we have started a new series to acquaint (or reacquaint) folks with @RegenPGC and our vision for using perennial groundcover in row crop fields for all kinds of interesting benefits.. This first video features Dr. Ken Moore and Roger Hintz, two members RegenPGC Team who have the most experience of anyone trying to manage and maintain yields when incorporating perennial ground cover into a row crop system –so, this video – https://lnkd.in/gbdgz9mQ is for you. (See the accompanying Field Notes at https://lnkd.in/gHQsGpXP)

We acknowledge that some of you may be unfamiliar with perennial groundcover and its potential for modern agriculture. Consequently, we have initiated a new series to educate (or reeducate) folks in the agriculture sector about RegenPGC and our vision for introducing perennial groundcover to the row crop landscape.

This video showcases Dr. Ken Moore and Roger Hintz, two individuals with extensive experience managing and maintaining yields when incorporating perennial ground cover into row crop systems. This video, accessible at https://youtu.be/MYQcSBZXVXQ, and you will find the accompanying Field Notes at https://iastate.box.com/s/fij94zkojl6kpaofkmepdk66cpzb0ij3.

Over the next several weeks, we will be dropping in more from this series into our blog. Stay tuned!

 

 

More honors and recognition for the RegenPGC Graduate Education Community

Our 18-member Graduate Education Community (https://www.regenpgc.org/theme-3-education/graduate-education-copy/) never stops impressing us with their dedication to good research and the RegenPGC vision.* But this month shows what an interesting and talented group we have.

Hallie Sandeen (University of Kentucky / Mentor Dr. Erin Haramoto) received a 1st place award at the University of Kentucky’s Integrated Plant & Soil Science Department Fall 2024 Symposium for her poster “Evaluation of Poacae Species and Suppression Application Methods for Permanent Groundcover in Corn.” Earlier this year, Hallie was recognized as the Weed Science Society of America’s 2025 Photographer of the Year! At the Society’s Annual Meeting in Vancouver.

We learned Graduate Student Jack Moran’s (Iowa State University / Mentors Drs. Susan Goggi & Ken Moore) interesting backstory of how he made it from Multyfarnham, Central Ireland, to Iowa State University. Jack’s Iowa State University ‘origin story’ was shared in an article by the ISU College of Agriculture and Life Sciences Office for Global Engagement. You can read “From Exchange Student to a Master’s Degree: a Global Journey to Iowa State University” at https://global.ag.iastate.edu/news/2025/exchange-student-masters-degree-global-journey-iowa-state-university

*Our vision is to create well-adapted PGC systems for a range of farm operations that require low labor inputs, provide significant ecosystem benefits, increase row crop resiliency, and have similar economic profiles as conventional row crop practices.
