e3“Combinations of Pilosella officinarum (mouse-eared hawk-weed, an invasive weed), Trifolium repens (white clover, a nitrogen fixer) and Dactylis glomerata (cocksfoot, a pasture grass) were planted into a soil with low-to-deficient concentrations of key nutrients”
e4“requirements for legumes to be the main source of nitrogen in pasture grasslands may be compromised unless competitive weeds are controlled”
Title
Invasive weed disrupts facilitation of nutrient uptake in grass-clover assemblage

Other claims from this paper (6)
- Intervention effect Grass-clover assemblages improved nutrient procurement for Dactylis glomerata
- Intervention effect Grass-clover assemblages improved nutrient procurement for Trifolium repens
- Observation Grass-clover growth gave complementary benefits in procurement of a wide range of soil nutrients despite lower root biomass
- Intervention effect Dactylis glomerata grown alone gave the highest yields compared with grass grown with clover
- Association The invasive weed Pilosella officinarum negated the nutrient-procurement benefits of grass-clover mixtures
- Intervention effect Pilosella grown alone or in mixture exploited soil nutrients less efficiently
