W. W. Moschler; D. C. Martens; C. I. Rich; et al. Agronomy Journal 1973. doi:10.2134/agronj1973.00021962006500050032x
Other claims from this paper (12)
- Intervention effect Surface lime increased no tillage corn yield by 31.3%.
- Intervention effect Incorporated lime increased conventional tillage corn yield by 13.5%.
- Observation Lime was needed for the highest corn yields under both tillage systems.
- Observation No tillage had higher topsoil pH than conventional tillage in year eight.
- Observation Liming under no tillage produced a larger increase in topsoil exchangeable Ca.
- Observation Liming under no tillage reduced topsoil exchangeable Al.
- Observation Subsoil pH and exchangeable Ca and Al were nearly identical under tilled and no tillage soil.
- Association Corn maturity correlated significantly with yield gain from lime.
- Mechanism The authors attribute lime deficient corn yield loss principally to reduced growth, especially early.
- Observation Growth reduction from lack of lime was more noticeable in no tillage corn.
- Intervention effect Lime increased ear dry matter more in no tillage corn than conventional corn.
- Observation Water use efficiency for lime induced grain yield gain under no tillage was almost three times conventional tillage.
