Recalling a Man Who Put Annual Ryegrass on the Cover Crop Map

Mike Plumer was a guy who made sure he knew what he was talking about before he’d open his mouth. He didn’t tout his academic degrees or his professional experience as much as giving you the benefit of his PERSONAL experience.

When it came to cover crops, Mike was out in front of practically the whole country. With his friend Ralph “Junior” Upton, Mike began to experiment with no-til and cover crops. Junior’s land, hilly with some bottom land and featuring a lot of fragipan layering, was as good a place to start as any.

What Mike and Junior noticed almost right away, back in the early 1990s, was that annual ryegrass was easy to germinate. It tolerates being wet, so the bottom land blossomed. And, though he approached this next step carefully, he saw that annual ryegrass killed easily in the spring, provided you do your homework on killing it properly.

One of the biggest surprises, however, was how deep annual ryegrass roots grow over the winter. Because the seed is raised in Oregon, on wet soils, the roots don’t need to grow deep to flourish. But in the Midwest, the moisture and nutrients are way deep sometimes, and annual ryegrass goes after it.

Thirty years hence, the Midwest continues to adopt cover cropping slowly, but surely. Farmers understand economics, and cover crops make money, in several ways. They improve soil quality, so the harvest is fuller. Annual ryegrass sequesters nitrogen, so you save on fertilizer input. And cover crops store carbon and build organic matter, which makes the land you own that much more valuable when it comes time to sell.

Mike Plumer, may he rest in peace. Who knows, perhaps there’s an Extension Service in heaven, and Mike’s been put to work building healthy futures there, too.
