- Intervention effect No-tillage reduced yield by 975 kg/ha or 13% versus plowing on Mollic Ochraqualf under continuous corn.
- Intervention effect No-tillage and plowing yielded equally in the other two rotations on Mollic Ochraqualf.
- Intervention effect No-tillage increased yield by 750 kg/ha or 10% versus plowing on Typic Fragiudalf under continuous corn or corn-soybeans.
- Intervention effect Other site-rotation combinations generally showed equal yield among tillage treatments.
