Annual Ryegrass – Now What?

Ok, so now the annual ryegrass is killed. It’s residue will soon become worm food. The decaying roots will become added food for a rich soil biology. The channels left by the decayed roots will create more friability in the soil…crumbly, pliable, spacious. Moreover, new corn and soybean roots will be able to find their way deeper into the soil profile, where added moisture and nutrients can build a more productive crop this year.

Some who are now contemplating corn planing activity may wish to consider adding a next round of annual ryegrass within a short time thereafter. For years now, producers have been having success with “interseeding” annual ryegrass into their corn, when it is less than knee high (V4- V5 stage).

We will cover this subject more in the coming weeks, but for now you could take a look at the following publications, each covering aspects of the reasons, the methods and the benefits of planting a cover crop in the spring.
