The broader impact/commercial potential of this I-Corps project is the adoption of a new standard for assessing the real-time condition of soil and geomaterials. The occurrence of extreme weather fluctuations and natural disasters have the potential to permanently disrupt modern society and agricultural practices by increasing soil erosion and decreasing usable land, soil fertility, and resistance to pests and disease. Growing populations will place more demand on agricultural production despite constrained amounts of available land. Technologies that assist with better nutrient management, planting, and harvesting techniques will aid in sustainable food production. Additionally, the need for better soil characterization and monitoring techniques are required in light of prominent failures of mine tailings dams. The safety of mining and large earth construction operations may be improved with the adoption of real-time, remote measurements of geomaterials. Lastly, more frequent and intense wildfires have led to more post-wildfire debris flows. Dangers associated with the debris flow potential must be identified and characterized. The optical, non-contact remote measurement technology that will be explored in this project has the potential to impact society as well as several markets and industries, ranging from precision agriculture to mining, hazard mitigation, and construction.This I-Corps project will explore the applications of optical infrared technology. The specific technology that will be explored was developed at the bench and field scale to remotely measure soil properties. The proposed innovation will advance agricultural and geotechnical engineering practices by enabling remote measurements of soil/crop condition and fertility, as well as static and dynamic soil parameters. Prior to the development of this technology, no method existed to remotely measure soil suction in the field. Because the measurements do not require contact with the soil, nor the collection of soil or water samples, the measurements are non-destructive. Furthermore, the rapidly collected measurements obtained will include many data points over a large area, improving spatial and temporal resolution over conventional point-wise data collection methods. The need to install labor-intensive and cost-prohibitive in situ instrumentation is then eliminated. The proposed technology also has the potential to save time and costs associated with conventional laboratory classification of soil properties and may also improve upon the poor reproducibility of some conventional testing methods.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是采用新标准来评估土壤和土地材料的实时状况。极端天气波动和自然灾害的发生可能会通过增加土壤侵蚀并降低可用土地，土壤肥力以及对害虫和疾病的抵抗力，从而永久破坏现代社会和农业实践。尽管可用的土地数量有限，但人口不断增长的人口将对农业生产提出更多需求。有助于更好地营养管理，种植和收获技术的技术将有助于可持续的粮食生产。此外，鉴于矿山尾矿大坝的显着故障，需要需要更好的土壤表征和监测技术。通过采用实时远程测量，可以提高采矿和大地建筑行动的安全性。最后，更频繁和强烈的野火导致了更多的野火碎片流。 必须确定和表征与碎屑流势相关的危险。 该项目将探讨的光学，非接触式远程测量技术有可能影响社会以及几个市场和行业，从精密农业到采矿，缓解危害和建设。光学红外技术的应用。 将要探索的特定技术是在板凳和田间尺度上开发的，以远程测量土壤特性。提出的创新将通过远程测量土壤/作物状况和生育能力以及静态和动态的土壤参数来推动农业和岩土工程实践。在开发该技术之前，没有任何方法可以远程测量该领域的土壤吸力。由于测量值不需要与土壤接触，也不需要土壤或水样的收集，因此测量值无损。此外，获得的快速收集的测量值将在大面积上包括许多数据点，从而改善了与传统的点数据收集方法相比，空间和时间分辨率。然后消除了安装劳动力密集型和成本良好的原位仪器的需求。拟议的技术还具有节省与传统实验室土壤特性分类相关的时间和成本的潜力，并且可能会改善某些常规测试方法的可重复性差的可重复性。该奖项反映了NSF的法定任务，并被认为是通过使用评估的支持，基金会的智力优点和更广泛的影响审查标准。
