Other claims from this paper (10)
- Association Tillage, N placement or their interaction affected corn yield in all seven corn crop years.
- Intervention effect Corn yields averaged about 25% lower under no-till than conventional or reduced tillage.
- Mechanism Nitrogen fertilization increased corn yield by increasing kernels per ear.
- Intervention effect Subsurface band N increased corn yield about 10% relative to surface application.
- Intervention effect Average wheat yield was unaffected by tillage.
- Intervention effect Adding N more than doubled wheat yield.
- Intervention effect Wheat yield differences between preplant N placement methods were small.
- Intervention effect Average double-crop soybean yield was unaffected by tillage.
- Intervention effect Tillage tended to increase soil P and K relative to no-till.
- Intervention effect No-till redistributed soil organic matter without a net increase.
