Effects of No-Till on Soil Organic Carbon

I previously shared information from Dr. Ken Olson of the University of Illinois concerning whether or not No-Till increases Soil Organic Carbon.  Dr. Olson has recently teamed up with other researchers in the Midwest to take a more broad look at the subject.  In this news article No-Till soil organic carbon sequestration rates are questioned by Dr. Olson and others.  Let's be clear that nobody is saying that No-till is a bad thing.  Dr. Olson is dedicated to soil conservation and the positive effect that No-till has on soil loss is not questioned.
