Other claims from this paper (14)
- Intervention effect Bulk density and soil strength in the upper layer were similar among the tillage and N treatments after 24 years.
- Intervention effect Soil strength at 50-60 cm depth was 28.2% higher under intensive tillage than under no-tillage.
- Intervention effect Soil moisture at 0-5 cm depth was 38.1% higher under conservation tillage than under intensive tillage.
- Intervention effect Soil temperature at 0-5 cm depth was 4.5% higher under conservation tillage than under intensive tillage.
- Intervention effect A high N rate decreased soil pH at 0-20 cm depth by 10%.
- Intervention effect A high N rate increased total soil N at 0-5 cm depth by 19%.
- Intervention effect At 0-10 cm depth, MT with no N had the highest exchangeable K.
- Intervention effect At 0-10 cm depth, intensive tillage with medium N rate had the lowest exchangeable K.
- Intervention effect At 0-5 cm depth, MT with no N had the highest exchangeable Ca.
- Intervention effect Exchangeable Ca at 0-5 cm depth was lowest when a higher N rate was combined with MT.

- Intervention effect Corn yield under long-term conservation tillage was 31.8% higher than under intensive tillage.
- Intervention effect Corn yield with 100 kg N ha-1 under long-term N fertilization was 36.4% higher than with no N.
