Other claims from this paper (9)
- Association High PAWC soil produced more shoot yield than low PAWC soil, 2600 versus 900 kg DM/ha.
- Association Lucerne on high PAWC soil extracted twice as much water to this depth.
- Observation Water use efficiency was 27.0 kg/DM/ha/mm at both sites.
- Association Leaf appearance rate was 48 degree-days per node and was unaffected by site.
- Association Leaf area expansion was strongly related to accumulated thermal time, with R2 above 0.94.
- Observation High PAWC leaf area increased exponentially at about 0.004 m2 leaf/m2 soil per degree-day.
- Observation Low PAWC leaf area increased linearly at 0.0009 m2 leaf/m2 soil per degree-day.
- Observation The soil moisture extraction front moved at 13 mm/day at both sites.
- Mechanism The authors attributed yield differences fully to water extraction differences to 1.2 m.
