LegumeLegacy - Optimising multiple benefits of grass, legume and herb mixtures in crop rotations: modelling mechanisms and legacy effects

通过《欧洲绿色协议》，欧盟承诺向碳中和和可持续的农业系统过渡。LegumeLegacy旨在利用生态学、农学、统计学和其他领域的最新知识，调整现有的以混合或反刍动物为基础的生产系统，最大限度地减少温室气体排放、养分投入和浸出（及成本），同时增加碳储量、生物多样性和产量稳定性。为了实现这一目标，LegumeLegacy的一个特殊和独特的策略包括在多个LegumeLegacy站点上进行一个共同的实验；10名博士研究员（dr；其中两名由瑞士政府资助）将在共同实验中合作，并有自己独特和互补的研究目标。为了建立一个作物轮作的模式系统，在共同的实验中，将6种不同物种（2种草，2种豆科植物，2种草本植物，选择互补的功能性状）的不同多样性的草地地块建立为草地，生长和终止；草地草地之后将种小麦。通过产量、质量和环境绩效指标来评价草地草地多样性对轮作效果的影响。LegumeLegacy将建议在作物轮作中设计草地轮作，以优化农艺和环境绩效；多地点实验将概括结论及其在整个欧洲实施的潜力。LegumeLegacy将培训10名博士成为新一代的未来领导者，他们将有能力在农业部门开发和部署跨学科和数据驱动的可持续实践。通过一个包括统计学、专业研究技能、有针对性的可转移技能和全球网络内的科学合作在内的培训计划，这批未来的领导者将具备在工业界或学术界一系列相关学科的专业技能。

With the European Green Deal, the EU has committed to transition to carbon-neutral and sustainable systems of agriculture. LegumeLegacy aims to adapt existing mixed or ruminant based production systems, using state of the art knowledge from ecology, agronomy, statistics and other fields to minimize greenhouse gas emissions, nutrient inputs and leaching (and costs), while increasing carbon stocks, biodiversity and yield stability. To achieve this, an exceptional and distinctive strategy of LegumeLegacy includes a common experiment across multiple LegumeLegacy sites; 10 Doctoral Researchers (DRs; two funded by the Swiss Government) will collaborate on the common experiment and have their own distinctive and complementary research objectives. To develop a model system of crop rotation, in the common experiment grassland plots of varying diversity of six species (two grasses, two legumes, two herbs, selected for complementary functional traits) will be established as a grassland ley, grown, and terminated; the grassland leys will be followed by a wheat crop. The effect of the diversity of the grassland ley on the performance of the crop rotation will be evaluated by measurement of yield, quality and environmental performance. LegumeLegacy will recommend the design of grassland leys within crop rotations that optimise agronomic and environmental performance; the multi-site experiment will generalise the conclusion and its implementation potential across Europe.LegumeLegacy will train a cohort of 10 DRs into a new generation of future leaders who will have the capacity to develop and deploy interdisciplinary and data-driven sustainable practices in the agricultural sector. With a training programme that includes statistics, specialised research skills, targeted transferable skills and scientific co-operation within a global network, this cohort of future leaders will be equipped with professional skills for a range of associated disciplines in industry or academia.
