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艾米丽蒋教授和拉斐尔桑托斯教授领导的研究小组在圭尔夫大学（UoG，圭尔夫，ON）和MANTECH公司之间的伙伴关系。（圭尔夫，ON）。该伙伴关系的主要目标是开发一种协议，通过光催化反应动力学快速测量土壤中的总有机碳（TOC）并对有机碳库进行分类。开发的协议将被集成到MANTECH现有的PeCOD分析仪进行快速和翔实的土壤TOC分析。将碳以总有机碳的形式封存在土壤中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，该技术旨在使农民能够采用增加土壤中TOC的农业实践，特别是稳定的有机部分，以实现长期缓解气候的目的。这项研究对加拿大减缓气候变化和改善农业环境指标的战略很重要本研究的预期成果和影响包括：1）开发一种快速、低成本地测定不同土壤有机碳组分的技术（即不稳定C、腐殖质C和抗性C）; 2）向农民和农民协会传授知识的活动（如OFVGA、OSCIA、OFA）、学者和政府机构代表（如OMAFRA、AAFC）为碳信用额搭建舞台; 3）对HQP进行先进仪器和分析技术培训。
