Other claims from this paper (5)
- Association Deep roots were advantageous across climate scenarios at the long growing-season site.
- Association Deep roots provided little or no advantage at the short growing-season site.
- Association Under climate-change scenarios, deep-rooted pasture produced 205 kg/ha/year less dry matter than shallower-rooted pasture at the short-season site.
- Association Timing of extra growth and pasture persistence strongly influenced the benefit from deep roots.
- Recommendation The authors suggest summer dormancy as an adaptation at the short-season site.
