Other claims from this paper (8)
- Observation Jointed goatgrass density averaged 8 plants/m 2 across rotations.
- Observation Feral rye density averaged less than 0.1 plant/m 2 across rotations.
- Intervention effect Downy brome density was below 0.5 plant/m 2 for both rotation lengths with no treatment difference.
- Observation Winter annual grasses persisted after two cycles of three-year rotations.
- Intervention effect Weed density after three-year rotations was over 100-fold lower than after two-year rotations.
- Observation Wheat grain contamination with dockage and foreign material followed the weed density trend.
- Observation Three-year rotations were economically competitive with two-year rotations.
- Intervention effect Three-year rotations controlled winter annual grass weeds better than two-year rotations.
