If I seeded red clover the 1st of september by air it would be lucky to get 2" tall by fall and roots would only be a couple inches deep also. The rye grows later into the fall and greens up the quickest in the spring and gives me lots of deep roots to benefit the soil. Your method/timing of killing the rye sound good and ought to reduce allelopathic effects. However, I think there will still be some issue with this at a mere 2 wks ahead of corn planting. (I'm referring to cereal rye). I agree that cereal rye grows faster than almost anything else over the winter. It's a great cover ahead of soybeans. |
