Other claims from this paper (10)
- Intervention effect Trifolium presence and abundance positively affected biomass production and complementarity in two-species mixtures from the second year.
- Intervention effect Leaf area, N and water-use efficiency were higher in communities containing Trifolium.
- Intervention effect Deep root growth was higher in communities containing Trifolium.
- Association Regression identified water acquisition and use traits together with N as main determinants of biomass production and complementarity.
- Mechanism Lower shallow root mass of Trifolium and higher soil moisture should increase water availability for associated grasses.
- Mechanism Higher deep root growth and lower soil moisture indicate increased soil resource use in mixtures.
- Mechanism Results highlight nitrogen facilitation and vertical soil differentiation supporting water complementarity in Trifolium mixtures.
- Observation Grass mixtures showed no significant over-yielding even when their traits were complementary.
- Mechanism Positive complementarity effects were time-dependent because Trifolium developed slowly, possibly due to grass competition.
- Mechanism Soil water resources were an important driver of over-yielding and complementarity in Trifolium-grass mixtures.
