In early 2009 I read an article about Rick Bieber similar to this in the VicNoTill magazine. That article, along with Wayne Smith's article, and our Bairnsdale trials, were my main encouragement to start growing corn. (Yes, I had to be told three times!)
An interesting quote from Rick: "No-till saves time, soil & water; Rotations manage time, soil & water."
