Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems. Organic Eprints
Baddeley, J. A.; Döring, Thomas F.; Hatch, David; Marshall, Athole; Pearce, Bruce; Roderick, S; Stobart, Ron; Storkey, Jonathan; Watson, C.A.; Wolfe, Martin.
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.

What makes a weed a weed? A large- scale evaluation of arable weeds through a functional lens Organic Eprints
Bourgeois, Bérenger; Munoz, Francois; Fried, Guillaume; Mahaut, Lucie; Armengot, Laura; Denelle, Pierre; Storkey, Jonathan; Gaba, Sabrina; Violle, Cyrille.
PREMISE OF THE STUDY: Despite long-term research efforts, a comprehensive perspective on the ecological and functional properties determining plant weediness is still lacking. We investigated here key functional attributes of arable weeds compared to non-weed plants, at large spatial scale. METHODS: We used an intensive survey of plant communities in cultivated and non-cultivated habitats to define a pool of plants occurring in arable fields (weeds) and one of plants occurring only in open non-arable habitats (non-weeds) in France. We compared the two pools based on nine functional traits and three functional spaces (LHS, reproductive and resource requirement hypervolumes). Within the weed pool, we quantified the trait variation of weeds along a...

Legume based plant mixtures for delivery of multiple ecosystem services: An overview of benefits Organic Eprints
Döring, Thomas F.; Baddeley, J. A.; Brown, RJ; Collins, R; Crowley, Oliver; Cuttle, Steve; McCalman, Heather; Pearce, Bruce; Roderick, Stephen; Stobart, Ron; Storkey, Jonathan; Watson, Christine; Wolfe, Martin; Jones, H E.
As costs for mineral fertilizers 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 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...

Modelling the ability of legumes to suppress weeds Organic Eprints
Storkey, Jonathan; Döring, Thomas F.; Baddeley, J. A.; Marshall, Athole; Roderick, S.; Jones, Hannah.
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...

A win-win for legume mixtures Organic Eprints
Döring, Thomas F.; Crowley, Oliver; Pearce, Helen; Storkey, Jonathan; Brown, Rob; Jones, Hannah.
The inter-relationship between food production and biodiversity is now well established. The ecosystem services provided by the organisms within the environment include, for example, nutrient cycling, pest regulation and pollination, to name but a few. However, perhaps the greatest challenge now facing agricultural production is to find ways of enhancing these ecosystem services, while at the same time increasing food production – particularly in light of food security issues. A range of farm and landscape management options include ‘setting aside’ land for wildlife. However, some proponents argue that such land should be used for food production. While the debate continues, there is no doubt that a large body of scientific evidence from the last three...

Legume Based Plant Mixtures for Delivery of Multiple Ecosystem Services: weed diversity and weed control Organic Eprints
Döring, Thomas F.; Storkey, Jonathan; Baddeley, J. A.; Crowley, Oliver; Howlett, S. A.; McCalman, Heather; Pearce, Helen; Roderick, Stephen; Jones, H E.
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...
