Annual Ryegrass: Not to Be Confused with Cereal Rye

As Earth Day rolls around, it’s a good reminder that the small decisions we make on the farm can have a big impact not just for our yields, but for the land we’ll pass on to the next generation.


One of those decisions? Cover Crops.

This practice is gaining traction across Illinois as farmers look for ways to improve soil health, reduce erosion, and keep nutrients where they belong all while keeping corn yields strong.


Why Annual Ryegrass?

Annual ryegrass is a tough, deep-rooted cover crop that plays a powerful supporting role in your corn-soy rotation. Here’s what it brings to the table:

  • Improved Soil Structure: Its fine root system breaks up compaction and enhances water infiltration.
  • Nutrient Scavenging: Captures leftover nitrogen and holds it in the root zone for the next crop.
  • Erosion Control: Helps shield your soil from wind and water erosion, especially during heavy spring rains.
  • Weed Suppression: Once established, ryegrass can outcompete early weeds and reduce your herbicide needs.


How Interseeding Works

Unlike traditional cover crops that are planted after harvest, interseeding lets you plant annual ryegrass during the corn growing season, typically at the V4–V6 corn stage. This gives the ryegrass a head start before the canopy closes.

You can use high-clearance interseeders, modified broadcast seeders, or even aerial application in some systems. The key is to get seed-to-soil contact and have some moisture available for germination.

Once the corn is harvested, the ryegrass takes off capturing nutrients, protecting soil, and prepping your ground for the next season.



Earth Day and Everyday Stewardship

Cover crops isn't just good stewardship, it’s good business. You’re building a more resilient soil system, reducing input losses, and creating long-term sustainability for your farm. Because around here, Earth Day isn’t just one day. It’s every day.

How much do you know about the farmers who came before you and the decisions that still shape Illinois agriculture today? That's what University of Illinois student Lyndon Shi set out to explore during his internship with IL Corn . What began as an archival research project became a deeper look at the history of farmer leadership, innovation and advocacy in Illinois. While digging through university archives, Lyndon uncovered an undigitized manuscript from agricultural economist Harold Guither explaining the case for checkoffs. When he mentioned the discovery to IL Corn Director Rod Weinzierl, he got an unexpected response: "Oh yeah, I know him. We worked with him." It was a reminder that agricultural history isn't as distant as it may seem. Lyndon's research connected two eras of the IL Corn Growers Association: the original organization founded in the 1890s and the modern ICGA established in the 1970s. He learned how University of Illinois agriculture dean Eugene Davenport helped organize corn growers and sent professors across the state on "Corn Gospel Trains" to share the latest farming research. One story stood out in particular: the adoption of hybrid corn. Farmers who once judged corn by the appearance of the ear had to shift their focus to yield. Lyndon sees a similar transition today, as farmers increasingly balance yield with profitability amid rising input costs. "Illinois corn farmers are very good at organizing, and they are genuinely very grassroots," Lyndon said. "They've had a much more active role in shaping policy rather than just being on the receiving end." This Summer and Fall, Lyndon will travel to Taiwan on a federal scholarship to study food security. He'll do so with a new appreciation for Illinois agriculture's global connections, including Taiwan's longstanding role as an important trading partner. Watch the full conversation on IL Corn TV to hear Lyndon's research firsthand and discover how Illinois corn's history continues to influence the future.
