This award was made through the "Signals in the Soil (SitS)" solicitation, a collaborative partnership between the National Science Foundation, the United States Department of Agriculture National Institute of Food and Agriculture (USDA NIFA) and the following United Kingdom Research and Innovation (UKRI) research councils: 1) The Natural Environment Research Council (NERC), 2) the Biotechnology and Biological Sciences Research Council (BBSRC), 3) the Engineering and Physical Sciences Research Council (EPSRC), and the Science and Technology Facilities Council (STFC). Phosphorous, one of the major three nutrients in fertilizer, is required for plant growth, and it serves as an indicator for global environmental sustainability. It is important to understand the variations of phosphate in soils and soil-water systems in order to address a number of global challenges such as food production and regulating fertilizer applications for crops grown in various soil conditions and climate regimes. The goal of this research project is to use the latest graphene-based technology to develop a low-cost sensor capable of real-time monitoring of the phosphorus content in soil. This collaborative project between researchers at the U.S. institutions of Kansas State University and the University of Alabama at Huntsville, and the U.K. institution of the University of Sheffield, will be conducted by an interdisciplinary team with expertise in soil and water science, geology, electrical engineering, and the fundamental chemistry and physics of soil-graphene interactions. Successful demonstration of such sensors would enable farmers to choose the right amount of fertilizer to apply to the fields. Consequently, this research will help to strengthen the national and economic security of both the U.S. and the U.K. and will strengthen the future workforce by bridging the gaps between science, technology, agriculture, and environmental disciplines through the training of graduate students, undergraduate students, and postdoctoral scientists. This research project aims to develop an additively-manufactured graphene sensor array and a portable wireless system for continuous in-field monitoring of electrochemical signals. Such a system would be applied to the mapping of soil phosphates in diverse agricultural landscapes in the US Midwest (Kansas) and the UK East Midlands (Derbyshire Dales and Peak District). Structurally and chemically tailored graphene materials will be used to print graphene sensors with quasi-3 dimensional and porous graphene morphologies. The materials will be designed to to achieve high electrical conductivity as well as reversible and high electron charge-transfer characteristics when exposed to soil phosphates. A fundamental understanding of phosphate ion binding with various graphene morphologies will be gained using state-of-the-art ultrafast laser spectroscopy and high-end computational modeling. A Bluetooth communication module with an Arduino platform will be constructed and interfaced with the sensor arrays for sensor data acquisition. Controlled environmental testing of spatial and temporal variations of phosphate ions over other interfering ions will be carried out at specific sites in Kansas and at Europe's largest controlled environment P3-facility housed at the University of Sheffield. The fundamental sensing characteristics and drift optimization with temperature, humidity, salinity, and soil pH will be identified and optimized for reliable data collection. Soils ranging from coarse calcareous to loamy montmorillonitic and silicate-rich soils in two countries will be utilized as testbeds to measure the sensing capabilities of the printed arrays. Furthermore, the project will explore the detection of phosphates over other interfering ions in soils, such as nitrates, silicates, and heavy metals, by using chemically-functionalized graphene sensors.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.

该奖项是通过“土壤信号（SitS）”征集获得的，该征集是美国国家科学基金会、美国农业部国家食品和农业研究所（USDA NIFA）以及以下英国研究与创新机构之间的合作伙伴关系(UKRI) 研究委员会：1) 自然环境研究委员会 (NERC)，2) 生物技术和生物科学研究委员会 (BBSRC)，3) 工程和物理科学研究委员会 (EPSRC)，以及技术设施委员会（STFC）。 磷是肥料中的三大营养素之一，是植物生长所必需的，也是全球环境可持续性的指标。 了解土壤和土壤水系统中磷酸盐的变化非常重要，以应对许多全球挑战，例如粮食生产和调节在不同土壤条件和气候条件下生长的作物的施肥量。 该研究项目的目标是利用最新的石墨烯技术开发一种能够实时监测土壤中磷含量的低成本传感器。这个合作项目由美国堪萨斯州立大学和阿拉巴马大学亨茨维尔分校以及英国谢菲尔德大学的研究人员合作，将由具有土壤和水科学、地质学、电气工程专业知识的跨学科团队进行，以及土壤-石墨烯相互作用的基础化学和物理学。此类传感器的成功演示将使农民能够选择适量的肥料施用于田间。 因此，这项研究将有助于加强美国和英国的国家和经济安全，并将通过培训研究生、本科生、缩小科学、技术、农业和环境学科之间的差距，加强未来的劳动力队伍。和博士后科学家。该研究项目旨在开发增材制造的石墨烯传感器阵列和便携式无线系统，用于连续现场监测电化学信号。 这样的系统将应用于美国中西部（堪萨斯州）和英国东米德兰兹（德比郡山谷和峰区）不同农业景观的土壤磷酸盐绘图。结构和化学定制的石墨烯材料将用于打印具有准三维和多孔石墨烯形态的石墨烯传感器。 这些材料的设计目的是在暴露于土壤磷酸盐时实现高导电性以及可逆和高电子电荷转移特性。 使用最先进的超快激光光谱和高端计算模型，将获得对磷酸盐离子与各种石墨烯形态结合的基本了解。将构建具有 Arduino 平台的蓝牙通信模块，并将其与传感器阵列连接以获取传感器数据。磷酸盐离子相对于其他干扰离子的空间和时间变化的受控环境测试将在堪萨斯州的特定地点和设在谢菲尔德大学的欧洲最大的受控环境 P3 设施进行。将确定并优化温度、湿度、盐度和土壤 pH 值的基本传感特性和漂移优化，以实现可靠的数据收集。两个国家的粗钙土、壤质蒙脱土和富含硅酸盐的土壤将被用作测试台，测量印刷阵列的传感能力。此外，该项目将探索使用化学功能化石墨烯传感器检测土壤中的磷酸盐，而不是硝酸盐、硅酸盐和重金属等其他干扰离子。该奖项反映了 NSF 的法定使命，并通过评估认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
