Other claims from this paper (14)
- Observation Bulk density was lowest under chisel tillage.
- Observation Bulk density was highest under no-till.
- Observation Soil temperature was highest in conventional and ridge systems.
- Observation Soil temperature was lowest under no-till.
- Association Soil temperature was higher after soybeans than after corn.
- Association Conventional tillage had lower soil moisture, especially with corn residue.
- Observation Soil pH was lowest at 7.5-15 cm following nitrogen incorporation.
- Observation Moldboard plowing distributed phosphorus and potassium through the plowed layer.
- Observation Treatments affected chemical elements in corn and soybean leaves.
- Intervention effect No-till had greater corn rooting density in the upper 7.5 cm than other tillage systems.
- Intervention effect No-till had lower corn rooting density at 7.5-15 cm than other tillage systems.
- Observation Soybean root density was higher in the upper layer and declined with depth across tillage systems.
- Association Soil temperature associated with residue cover most affected differences in corn yield among treatments.
- Association Soybean yield did not significantly correlate with any studied variable.
