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.
