项目摘要

Livestock slurry is a valuable source of nutrients but is not always used efficiently in the agricultural sector in the UK, largely as a result of inadequate infrastructure, land use constraints, differences in soil types and climate, and a lack of integrated planning with inorganic fertiliser use. Better management of slurry which values its potential to meet crop demands for nutrients, or as an energy resource for anaerobic digestion (AD), whilst minimising its negative impacts on land and water quality is necessary to ensure a resilient and sustainable agricultural system, meeting both economic and environmental needs. Despite a considerable amount of knowledge and practical know-how about slurry storage and use, much of it targeted directly at farmers, slurry management on many farms continues to be ad-hoc and sub-optimal in economic, environmental and social terms.This project aims to pool together available knowledge on slurry management and use, with expertise about how science can be effectively translated, to improve the effectiveness of slurry produced on beef farms as a nutrient source and reduce its negative environmental impacts. It will do this by reviewing the current tools available to farmers for slurry management in the devolved countries and elsewhere in Europe. It will then explore (with both current and future beef famers and arable farmers) how they access and use information about the nutrient value of slurries produced (or potentially used) on their farms and how to best manage them. By working with farmers to understand the key knowledge gaps, environmental, cultural and other factors which affect their decision making around slurry management/use we will identify approaches which influence their decision making towards maximising the value of slurry enabling them to make the most of the information available to them. We will also identify the off-farm infrastructural constraints that connect to on-farm practices and currently impede optimal use of slurry.The outputs of the research (a. information design projects in collaboration with existing tool experts and providers (ADAS); b. incorporation of aspects of social understanding and innovation (e.g. farmer-to-farmer cooperation) into existing tools; c. knowledge production and knowledge exchange with policy around infrastructural innovation for slurry beyond the farm gate) have clear potential applications and benefits. The applications will be primarily relevant for farm level management of nutrients. The research will help enable beef farmers to optimise the nutrient benefits of their slurry to maximise production (of grass and livestock) from their farms and potentially to benefit economically from the export of excess nutrients to arable farms or anaerobic digesters (AD). We would also hope to positively influence the potential for arable farmers to benefit from the export of excess nutrients from beef farms through enhanced production of crops. Finally we hope to discuss with policy and institutional bodies of the off-farm infrastructural constraints that impede optimal use of slurry and to think through off-farm innovations that may be needed to support the on-farm innovations of farmers.Optimising the use of slurry as a nutrient source on land and reducing the potential loss of nutrients from land due to inappropriate use of slurry will be of significant environmental benefit for land, water and air quality. This will result in significant benefits for both private and public sectors beyond farmers, for example, through decreased costs of water treatment and improved environmental quality for users of the rural environment including tourists, rural dwellers and fishermen.

牲畜泥浆是一种宝贵的营养来源，但在英国农业部门并不总是有效利用，主要是由于基础设施不足、土地使用限制、土壤类型和气候的差异，以及缺乏无机肥料使用的综合规划。更好地管理浆液，重视其满足作物对养分需求的潜力，或作为厌氧消化（AD）的能源资源，同时尽量减少其对土地和水质的负面影响，这对于确保有弹性和可持续的农业系统，满足经济和环境需求是必要的。尽管有大量关于浆液储存和使用的知识和实践技能，其中大部分是直接针对农民的，但许多农场的浆液管理在经济、环境和社会方面仍然是临时的和次优的。该项目旨在汇集有关肉糜管理和使用的现有知识，以及如何有效转化科学知识的专门知识，以提高肉糜作为营养来源的有效性，并减少其对环境的负面影响。它将通过审查目前在权力下放国家和欧洲其他地方农民可用的泥浆管理工具来做到这一点。然后，它将（与当前和未来的牛肉养殖户和耕地养殖户一起）探索他们如何获取和使用有关其农场生产（或可能使用）的浆液营养价值的信息，以及如何最好地管理它们。通过与农民合作，了解影响他们在泥浆管理/使用方面决策的关键知识差距、环境、文化和其他因素，我们将确定影响他们决策的方法，使泥浆的价值最大化，使他们能够充分利用可获得的信息。我们还将确定与农场实践相关的非农基础设施限制因素，这些限制因素目前阻碍了浆液的最佳使用。研究成果(a.与现有工具专家和供应商合作的信息设计项目（ADAS）；B.将社会理解和创新的各个方面（例如农民对农民的合作）纳入现有工具；C.知识生产和知识交流与围绕基础设施创新的政策（农场大门以外的浆料）具有明显的潜在应用和效益。这些应用将主要与农场一级的养分管理有关。该研究将有助于肉牛养殖户优化其肉浆的营养效益，以最大限度地提高农场（草和牲畜）的产量，并有可能从将多余的营养物质出口到耕地或厌氧消化器（AD）中获得经济效益。我们还希望通过提高作物产量，积极影响耕种农民从牛肉农场出口过剩营养物质中获益的潜力。最后，我们希望与政策和制度机构讨论阻碍最佳使用浆液的非农业基础设施限制，并思考可能需要的非农业创新来支持农民的农场创新。优化浆料作为土地养分来源的使用，减少由于不适当使用浆料而导致的土地营养物质的潜在损失，将对土地、水和空气质量产生重大的环境效益。这将为农民以外的私营和公共部门带来重大利益，例如，通过降低水处理费用和改善包括游客、农村居民和渔民在内的农村环境使用者的环境质量。
