Barley growing systems towards the net zero economy

向净零碳经济的发展是英国所有工业部门的主要推动力。在大麦供应链中——从作物育种、种植到加工——利益相关者正在寻求在保持大麦生产力和产品质量的同时，全行业减少碳足迹。以麦芽威士忌生产为例，大麦种植的排放量几乎占该行业碳排放总量的40%。虽然麦芽、蒸馏和酿造过程有可能通过可再生能源减少碳排放，但大麦种植系统可能需要几种不同的策略，包括土壤管理、肥料使用和农艺，以提高效率和碳中和。该项目的目的是重新设计大麦种植系统，以支持整个大麦供应链向净零经济过渡。通过在一系列不同天气和土壤条件下的田间试验，春大麦种植系统将被剖析为基因型(G)、环境(E)和管理(M)对整体生产效率和减少作物碳足迹的贡献。基于碳和氮流的作物和土壤测量将与“Agrecalc”碳核算工具相结合，使该研究能够量化G x E x M效应，包括作物的农艺价值和新管理的潜力，如减少或新肥料的使用。对种植系统的详细分析将通过两个BARIToNE商业合作伙伴——Chivas brothers和Opportunity NE——主持的案例研究与更广泛的大麦供应链联系起来。芝华士兄弟（Chivas Brothers）主持的Glenlivet Estate案例研究，以及对粮食供应的分析和通过Opportunity NE进行的农场示范，将构成该项目的产出框架。在整个研究项目中，学生将有机会参与SRUC和JHI在农学，作物改良和碳核算方面的更广泛的战略研究项目。该项目将农业与作物改良和谷物加工联系起来，将支持BARIToNE保障本地可持续优质大麦生产的战略目标。大麦种植系统实现净零经济的预期产出将包括对农民的指导、谷物生产和最终用途之间碳核算的连通性，以及将大麦种植与植物育种和品种测试联系起来的新作物种植协议。

Progression to the net zero carbon economy is a major driver across all UK industry sectors. In the barley supply chain - from crop breeding, farming and processing - stakeholders are seeking sector-wide reduction in carbon footprints whilst maintaining barley productivity and product quality. Taking the example of malt whisky production, emissions from barley growing account for almost 40% of the sector's total carbon release. Whilst processes of malting and distilling, and brewing, have potential to reduce carbon emissions through renewable energy sources, barley growing systems may require several different strategies involving soil management, fertilizer use and agronomy in-order to become more efficient and carbon neutral. The aim of this project is to re-design barley growing systems to support the whole barley supply chain's transition to the net zero economy. Working with field experiments under a range of different weather and soil conditions, spring barley growing systems will be dissected as contributions from the genotype (G), environment (E) and management (M) to overall production efficiency and reducing the crop's carbon footprint. Crop and soil measures based on carbon and nitrogen flow will be coupled with the 'Agrecalc' carbon accounting tool to allow the study to quantify G x E x M effects, including a crop's agronomic value and potential for new management such as reduced or novel fertilizer use. This detailed analysis of the growing system will be linked to the wider barley supply chain through case studies hosted by two BARIToNE commercial partners - Chivas Bothers and Opportunity NE. The Glenlivet Estate case study hosted by Chivas Brothers along with analysis of grain supply and farm demonstration through Opportunity NE will frame outputs from the project. Throughout the research programme, the student will have opportunity to engage with a broader programme of strategic research at SRUC and JHI in agronomy, crop improvement and carbon accounting. This project which connects farming with crop improvement and grain processing will support BARIToNE's strategic aim to safeguard the production of local and sustainable high-quality barley. Expected outputs for barley growing systems towards the net zero economy will include guidance to farmers, connectivity in carbon accounting between grain production and end usage, and new crop growing protocols to connect barley growing to plant breeding and variety testing.
