This year we are planting winter rye as our cover crop. Why rye, you ask? Well, let’s back up and talk about the importance of cover crops, in general. Planting a cover crop is a great way to add organic matter to soil. It also helps break up clay soils to help with drainage and you can till it all in next season a few weeks before you are ready to plant. Winter rye is supposed to be the best cover crop for fall planting and should thrive even in poor soils. OSU Extension is a great resource to learn more.
