Potential widespread adoption of regenerative agricultural practices, such as cover cropping, has documented capacity to contribute to net-zero emissions goals at the national level, often by sequestering carbon in soils through plant-mediated activity. However, there are methodological challenges in knowing if a management change has, or will result in, increased carbon sequestration in soil. Our research will develop technologies and techniques that can enable farm-level monitoring and decision making of plant-mediated, regenerative solutions for achieving carbon sequestration goals. Specifically, we will advance existing technologies of near-surface and sub-surface imaging of plant roots as potential sources of carbon inputs to soil, and make first steps in the development and calibration of novel electro-chemical bio-sensors to track metabolites of carbon inputs into longer-term pools of soil carbon. We will contextualize our research and findings with diverse farmer groups' feedback on regenerative practices and potential carbon and soil health monitoring tools, and perceived importance in achieving long-term management goals. Our partnerships will deepen the relevance and expand the potential end use of our research through i) increased reach with farmers through knowledge translation and transfer workshops and ii) in ensuring our approach has feasibility for on-the-ground industry application in measuring, monitoring, and verification of carbon and soil health changes on farms. Results from our research will increase the tangible near- and long-term capacity for farmers to quantify soil carbon sequestration - which can facilitate participation in carbon offsetting programs, but also more generally can bolster bottom-up capacity in running climate-smart farm operations.

潜在的广泛采用再生农业实践（例如覆盖种植）已经证明了在国家一级为零净排放目标做出贡献的能力，通常是通过通过植物介导的活动隔离土壤中的碳。但是，知道管理变更是否存在或会导致土壤中的碳固存增加，存在方法论上的挑战。我们的研究将开发技术和技术，以实现植物介导的，再生解决方案，以实现碳固存目标，以实现农场级的监测和决策。具体而言，我们将推进现有的近地表和植物根的地下成像的技术，作为土壤碳输入的潜在来源，并在开发和校准的新型电化学生物传感器的开发和校准方面迈出了第一步，以跟踪碳代谢物输入土壤碳的长期池。我们将通过各种农民团体对再生实践以及潜在的碳和土壤健康监测工具的反馈，并认为我们的研究结果将我们的研究和发现与之相关，并认为在实现长期管理目标方面具有重要意义。我们的伙伴关系将通过知识翻译和转移研讨会以及ii）提高与农民的覆盖范围，并扩大我们的研究的潜在最终用途，以及ii）确保我们的方法在测量，监测，监测，监测，监测，监测，监测，监测，以及对农场的碳和土壤健康变化的验证。我们研究的结果将增加农民量化土壤碳固存的近期和长期能力 - 这可以促进参与碳抵消计划的参与，但通常可以在运行气候舒适的农业运营中加强自下而上的能力。
