- Intervention effect Manure plus deep tillage increased corn yield relative to conventional tillage.
- Intervention effect Manure plus deep tillage improved solonetz soil properties relative to conventional tillage.
- Intervention effect The mulched manure and deep tillage treatment produced 11 472 kg ha-1 corn yield in 2013, 38% above control.
- Intervention effect The mulched manure and deep tillage treatment produced 12228 kg ha-1 corn yield in 2014, 43% above control.
- Observation Manure and deep tillage separated soils into two property groups.
- Association Corn yield correlated positively with urease and available P.
- Association Corn yield correlated negatively with pH, electrical conductivity, exchange sodium percentage, and bulk density.
- Association Bulk density was interpreted as the dominant factor for corn yield.
