| Organic farming aims to create an integrated, humane, environmentally and economically sustainable agricultural system. For organic dairy systems, the fulfilment of these aims requires the understanding and integration of a number of systems components including land use (mixed or dairy only) and stocking rate; grassland and forage production (including quantity and quality); potential milk yield (and milk quality); animal nutrition (largely farm based) and health; environmental sustainability such as farm nutrient balance; the financial status of the farm (including enterprise performance, fixed costs and labour use and farm income and profit) and finally the policy environment in which organic dairy systems operate. This review discusses worldwide... |

| Optimising the amount of nitrogen captured by fertility building crops is essential for successful organic farming. This study used a combination of literature review, empirical measurements, model development and farmer participation to produce improved guidelines on making the most of soil nitrogen for organic farmers and growers. The main field experiment examined the impact of cutting and mulching on the build up of soil nitrogen. Recommendations to organic farmers from this part of the work, are that cutting and removing herbage during the fertility building phase promotes the highest amount of nitrogen fixation. However the highest soil residues occurred when clover was mulched in situ. Application of organic manures to legumes should also be avoided... |

| 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... |
