Planting Corn in Cereal Rye Cover Crop

We have seen issues with planting corn into cereal rye cover crops.  I have always thought that killing the cereal rye early could help.  Researchers at Iowa State University have found that cereal rye supports the growth of microbes that can be damaging to corn seedlings.  They found that earlier kills worked better.  They also suggest that nitrogen at planting time can help promote healthier corn plants.  We have also found that with low soil test sulfur, rye can create a sulfur deficiency.  Sulfur at planting is also a good idea.  See what they say about reducing the risk of corn seedling disease and yield loss after cereal rye.
