The University of Nebraska will receive $749,861 under a four-year Project Grant from the United States Department of Agriculture National Institute of Food and Agriculture to study nitrogen movement and transformations in the vadose zone beneath agricultural lands. Funded through the Agriculture and Food Research Initiative competitive grants program, the University will measure occurrences of inorganic and organic nitrogen species below irrigated and dryland cornfields using deep coring....
This $300,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to enhance the resilience of groundwater resources in major U.S. agricultural regions through a participatory planning approach. The project team at Southern Illinois University, with sub-awards to Iowa State University and the University of Nebraska, will develop an AI-based modeling system to empower farming communities in addressing groundwater depletion and...
The University of Nebraska received a $492,056 Project Grant award from the US Geological Survey Office of Acquisitions and Grants under the Assistance to State Water Resources Research Institutes federal grant program (CFDA 15.805). The award will fund a research project titled "Nitrate Loading and Legacy Effects on Nitrogen and Carbon Cycling in Playa Wetlands of the High Plains" from February 7, 2023 through February 6, 2026. The project will conduct field studies and laboratory...
This $558,346 Project Grant awarded by the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) supports research at the University of Nebraska on the release, adsorption, and biotransformation of per- and polyfluoroalkyl substances (PFAS) at the water-sediment interface in agricultural watersheds. The key objectives are to: 1) measure the kinetics of PFAS release from decomposed biosolids and adsorption to sediments under anaerobic...
This project grant from the United States Department of Agriculture National Institute of Food and Agriculture's Agriculture and Food Research Initiative (AFRI) program provides $649,697 to develop an integrated assessment model called Hydroecon to measure the social costs of nutrient pollution across the United States through 2026. The University of Massachusetts leads a team that includes Cornell University, Iowa State University, and the University of Wisconsin-Madison to integrate economic...
This Project Grant award for $260,103 was provided by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) to the University of Illinois. The primary objective is to better understand the linkages between subsurface storage, flow path variations, and biogeochemical nitrogen cycling in tile-drained Midwestern agricultural watersheds. The research will integrate water age data and nitrate isotope analysis to quantify nitrogen source-sink strength and mass balance. The...
The U.S. Geological Survey (USGS) awarded a $485,717 Project Grant under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) to Iowa State University of Science and Technology. The grant, awarded on June 11, 2025, supports the development of an AI-driven platform to enhance water resource management capabilities across the United States, with a focus on Iowa as a case study. The key products and services to be delivered through this grant include: Integration of...
This $179,640 Agriculture and Food Research Initiative (AFRI) project grant, awarded by the USDA National Institute of Food and Agriculture, aims to improve understanding of nitrogen pollution in agricultural watersheds and develop better methods for managing and reducing this pollution. The project uses a combination of field experiments, sensor technology, and computer-based mapping tools to study the causes of post-storm nitrate enrichment - elevated nitrate levels in streams after storms....
The University of Nebraska was awarded a $300,000 Project Grant from the United States Department of Agriculture National Institute of Food and Agriculture under the Agriculture and Food Research Initiative (AFRI) federal grant program. The three-year grant will fund research and extension activities to evaluate the impact of interseeded cover crops on nitrogen dynamics and cycling in corn and soybean cropping systems in Nebraska. Specifically, the university will investigate how cover crops...
The U.S. Geological Survey (USGS) awarded a $576,061 Project Grant under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) to the University of Nebraska-Lincoln. The grant supports the development of an integrated crop-soil-groundwater model to enhance understanding of nitrate transport and transformation in agricultural regions. Key activities include:
Integrating crop models for corn, soybean, and potato into a new simulation model that can depict 3D soil and groundwater processes. Testing the model in farming areas to analyze nitrogen movement through the soil and groundwater. Exploring the use of artificial intelligence to predict spatial nitrate levels based on real-world and model data. The goal is to provide groundwater managers, policymakers, and farmers with insights to develop environmentally-friendly farming practices that maintain crop productivity while reducing groundwater nitrate contamination. The project will generate research articles, reports, model code, and documentation to benefit stakeholders in agricultural regions.
