TL;DR: In this article, the above-ground biomass of four-species mixtures (two legumes and two grasses) in intensive grassland systems was consistently greater than that expected from monoculture performance, even at high productivity levels.

TL;DR: A coordinated continental-scale field experiment was used to compare the biomass yield of monocultures and four species mixtures associated with intensively managed agricultural grassland systems and found that mixtures maintained a resistance to weed invasion over at least 3 years.

TL;DR: Effects of diversity on weed suppression were consistently strong across mixtures varying widely in species' proportions and over time, and these diversity benefits in intensively managed grasslands are relevant for the sustainable intensification of agriculture and, importantly, are achievable through practical farm‐scale actions.

TL;DR: Evidence strongly supports the sowing of multi-species mixtures that include legumes over the long-standing practice of sowing grass monocultures to facilitate the maintenance of species diversity and especially persistence of legume over time, and to preserve the strength of yield increases associated with diversity.
