This PFI: AIR Technology Translation project focuses on translating agricultural soil sensor development research into accurate monitoring of spatio-temporal variation of soil properties of agricultural interest. The development of the proposed soil sensors is important because they can enable the real-time, in-place monitoring of soil moisture, salinity, and nutrients in production agriculture, thus enabling precise nutrient management. This project will result in a feasible design/prototype of an in-situ soil sensor for agricultural application. This soil sensor has the unique features that it can measure the soil properties mentioned above in real-time when deployed in an underground grid configuration with support for wireless interaction. Current sensing systems do not support continual in-situ monitoring and also require manual operation, while the proposed system is a fully-automated solution, capable of continual in-situ monitoring and wireless transport.This project addresses technical gaps as it translates from research discovery toward commercial application in soil sensors for agriculture. Specifically in this project, sensor prototypes, using dielectric-based moisture/salinity sensing and electrophoretic nitrate sensing packaged with signal processing and wireless capability for underground deployment, will be tested and evaluated.In addition, personnel involved in this project, namely the two PhD students, will receive innovation and technology translation experiences through soil sensor development and evaluation research, regular participation in interactions with the Iowa State Office of Intellectual Property and Technology Transfer for disclosures and patents, and further interactions with agricultural domain industries for licensing, technology transfer and commercialization.The project engages Microwaves by the Weber, Inc. as a consultant with experience in product design, development and commercialization to augment the team's research capability, and guide commercialization aspects in this technology translation effort from research discovery toward commercial reality.

该项目致力于将农业土壤传感器的开发研究转化为对农业土壤特性时空变化的准确监测。拟议的土壤传感器的开发非常重要，因为它们可以在生产农业中实现对土壤水分、盐分和养分的实时、就地监测，从而实现精确的养分管理。该项目将产生一种用于农业应用的现场土壤传感器的可行设计/原型。这种土壤传感器的独特之处在于，当部署在支持无线交互的地下网格配置中时，它可以实时测量上述土壤属性。目前的传感系统不支持连续的现场监测，也需要人工操作，而拟议的系统是一个全自动化的解决方案，能够连续的现场监测和无线传输。该项目解决了从研究发现到农业土壤传感器的商业应用的技术空白。具体地说，在这个项目中，将测试和评估传感器原型，使用基于介质的水分/盐度传感器和具有信号处理和无线功能的电泳式硝酸盐传感器，用于地下部署。此外，参与该项目的人员，即两名博士生，将通过土壤传感器的开发和评估研究，定期参与与爱荷华州知识产权和技术转让办公室的互动以获得披露和专利，以及与农业领域行业的进一步互动，以获得许可、技术转让和商业化。该项目使用韦伯公司的微波作为具有产品设计经验的顾问，开发和商业化，以增强团队的研究能力，并引导这项技术转化工作中的商业化方面从研究发现转向商业现实。
