Other claims from this paper (7)
- Intervention effect Aboveground weed biomass did not differ between soybean production strategies.
- Observation Both soybean strategies had high variation in weed abundance across years.
- Intervention effect Tillage-based soybean production raised grain yield by 0.28 Mg ha −1 compared with reduced tillage.
- Association Soybean stand establishment and weed biomass were the primary modeled drivers of soybean yield.
- Intervention effect The reduced-tillage soybean sequence caused 50% less soil disturbance than the tillage-based sequence.
- Intervention effect The reduced-tillage soybean sequence had lower input costs.
- Intervention effect The reduced-tillage soybean sequence was approximately $114 ha −1 less profitable because average yield was lower.
