- Intervention effect Soil total C and N ranked TO ≥ IC > IF ≥ CO.
- Intervention effect Labile C and N ranked TO ≥ IC > IF ≥ CO in 70- and 150-day incubations.
- Intervention effect Mineralizable N tended to increase after soybean in all systems.
- Intervention effect Mineralizable N tended to decrease after corn in all systems.
- Association Corn yield was closely associated with 70-day N mineralization potential.
- Intervention effect First-year corn with cover had greatest yield under all management types.
- Intervention effect Continuous corn without cover had least yield.
- Intervention effect TO produced the lowest second-year or continuous corn yield.
- Intervention effect IC produced the lowest second-year or continuous corn yield.
- Intervention effect Commercially fertilized corn had higher fall nitrate and nitrate leaching than other crops or compost-amended corn.
