A few days ago I combined the corn on a farm we just purchased. Actually we purchased the 70 acres adjoining the 10 acres we already owned and have no tilled for 10 years. No tilled it straight through this year and observed something interesting. As I worked back and forth across the old property line the yield monitor consistently showed a ten to twenty bushel increase when harvesting the area I have no tilled for a long period of time. The new ground has always been field cultivated and planted but has not really been abused. I did soil test these areas separately and the new ground actually showed a little better fertility levels. Has anyone else ever noticed this? What do you folks think?
