Other claims from this paper (4)
- Intervention effect Long-term conservation tillage increased soybean yield by an average of 0.74%.
- Intervention effect The yield effect of conservation tillage was diminished in fields that only recently converted.
- Observation Yield responses to conservation tillage varied significantly, and soil and weather characteristics mediated their direction and magnitude.
- Recommendation Conservation tillage can be used with minimal and typically positive yield impacts.
