| There is a pressing need to develop arable cropping systems that are both more efficient in their use of nitrogen (N) and more resilient to an increasingly variable and unpredictable climate. One potential solution is to use species-rich mixtures of grasses and legumes in the fertilitybuilding phase of a ley/arable crop rotation. These mixtures may reduce N losses and increase productivity of the following crop. They may also have other important benefits such as increased in-field biodiversity. In this project, legume and grass species with a range of tolerances to different environmental conditions, and with differing growth characteristics, are being grown individually and as a mixture across the UK, and their performance assessed. |

| As costs for mineral fertilisers rise, legume-based leys are recognised as a potential alternative nitrogen source for crops. Here we demonstrate that including species-rich legume-based leys in rotations helps to maximise synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures, these services can be optimised and fine-tuned to regional and farm-specific needs. Replicated field experiments were conducted over three years at multiple locations, testing the performance of 12 legume species and 4 grass species sown in monocultures, as well as in a mixture of 10 of the legumes and all 4 grasses (called the All Species Mix, ASM). In addition, we compared this complex mixture to farmer-chosen... |

Here we demonstrate that including species-rich legume-based leys in the rotation helps to maximize synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures these services can be optimised and fine-tuned to regional and farm-specific needs. Field experiments run over three years at multiple locations showed that the stability of ley performance was greater in multi-species mixtures than in legume monocultures. In addition, mixing different legume species in the ley helps to suppress both early and late weeds. Further, combining complementary phenologies of... |

| Data from the second year of experiments at three sites (Wakelyns in SE and Sheepdrove in SW England; and Chapel Farm in SE Scotland) to investigate the effects of interactions among a range of agronomic practices (row spacing, seed density, weeding and undersowing with clover) on winter wheat performance are presented, and compared with first year results. Trends seen at all years and sites indicate that narrow row drill arrangements with high seed rates result in the highest yields. This combination also performed well for emergence and establishment. The effect of drill arrangement was significant (P<0.05) at two of the three experimental sites with establishment of 282 and 232 plants m-2 at Sheepdrove and Chapel farm respectively. There were... |

| The ability of different legume cover crops to suppress annual weeds during the early establishment phase was compared using a simulation model of inter-plant competition and field observations. Height, partitioning parameters, extinction coefficients, crop density and time of emergence were recorded for 11 species sown in monocultures. A naturally occurring population of fat hen (Chenopodium album) was present on the experiment. The competition model was run to compare the expected suppressive ability of the different species on this weed. Samples of C. album were also taken from each plot immediately prior to cutting to provide some empirical observations. Predicted suppressive ability was correlated with seed size and height with large seeded, tall... |

| Legume-based leys offer multiple benefits to ecosystem service provision, e.g. protecting soil and supporting pollinators. While weeds can play an antagonistic role during ley establishment, little is known about weed communities in these leys or about the optimal solutions for weed control in the establishment phase. To determine if the choice of ley species affects weed levels, we conducted field trials at six locations in the UK, measuring weed cover and biomass in monoculture plots of 12 legume and 4 grass species, plus an all species mix over two years. In these trials and in additional on-farm trials, weed cover and diversity were lower in the second than in the first year, owing to a decrease of annual weeds over time. The ability of a diverse... |
