Other claims from this paper (9)
- Intervention effect Flotation-tire compaction significantly reduced yield in one year only.
- Observation Yield reductions from compaction disappeared after one year.
- Intervention effect Deep tillage after compaction raised yield by 17% in one year.
- Intervention effect Shallow tillage did not increase yield.
- Intervention effect Heavy traffic following deep tillage removed its yield improvement.
- Intervention effect Deep tillage and uncompacted no-tillage yielded similarly for the first three years.
- Intervention effect Uncompacted no-tillage yielded more than deep tillage in 2005.
- Intervention effect In-row tillage substantially reduced residue cover.
- Recommendation The authors suggest little need for in-row tillage under the specified axle load and flotation-tire conditions.
