The proposed research project includes a partnership between the research team led by Prof. Emily Chiang and Prof. Rafael Santos at the University of Guelph (UoG, Guelph, ON) and MANTECH Inc. (Guelph, ON). The primary goal of the partnership is to develop a protocol to rapidly measure total organic carbon (TOC) and classify the organic carbon pools in soils, via photocatalytic reaction kinetics. The developed protocol will be integrated into MANTECH's existing PeCOD analyzer to carry out rapid and informative soil TOC analysis. Sequestering carbon as TOC in soil is seen as one way to mitigate climate change by reducing atmospheric carbon dioxide. Therefore, this technology is envisioned to enable farmers to adopt agricultural practices that increase TOC in soils, and in particular the stable organic fraction, for long lasting climate mitigation purpose. This research is important to Canada's strategies for climate change mitigation and improving Agri-Environmental Indicators (e.g. CO2 emission).The intended outcomes and impacts of this study include: 1) development of a technique to rapidly and at low cost determine the different soil OC fractions (i.e. labile C, humus C, and resistant C); 2) knowledge transfer activities to farmers and farmer associations (e.g. OFVGA, OSCIA, OFA), academics, and representatives of government institutions (e.g. OMAFRA, AAFC) to set a stage for carbon credits; 3) training of HQP in advanced instrumentation and analytical techniques.

拟议的研究项目包括由Emily Chiang教授和Guelph大学Rafael Santos领导的研究团队（UOG，Guelph，On）和Mantech Inc.（安大略省Guelph）领导的研究团队。合作伙伴关系的主要目标是制定一项方案，以快速测量有机碳（TOC），并通过光催化反应动力学对土壤中的有机碳池进行分类。开发的协议将集成到MANTECH现有的PECOD分析仪中，以进行快速而有用的土壤TOC分析。隔离的碳与土壤中的TOC被视为通过减少大气二氧化碳来缓解气候变化的一种方法。因此，该技术设想使农民能够采用农业实践，这些习俗可以增加土壤中的TOC，尤其是稳定的有机分数，以实现持久的气候缓解目的。这项研究对于加拿大为缓解气候变化和改善农业环境指标（例如CO2排放）的策略很重要。这项研究的预期结果和影响包括：1）开发一种快速和低成本的技术，以确定不同的土壤分数（即不稳定的C，Humus c，Humus c和combistant C）； 2）向农民和农民协会（例如Oscia，Oscia，ofa），学术界和政府机构（例如Omafra，AAFC）的知识转移活动，以设定碳信贷阶段； 3）在高级仪器和分析技术中培训HQP。
