Title: Integration of Multimodal Geospatiotemporal Data to Support Nutrient Recovery for Nitrogen-Based Fertilizers
Keywords: Geospatiotemporal data, manuresheds, multimodal data integration
Abstract: Nutrient pollution from agricultural runoff remains a key driver of eutrophication in water systems across the United States. Addressing this challenge requires both local and nationwide understandings of how nitrogen flows through watersheds and the environment. This research offers a novel framework for integrating multimodal (i.e. raster, line, point) geospatiotemporal datasets across varying spatial and temporal resolutions, from satellite imagery to watershed boundaries and point-source pollutant discharges. This pipeline enables high-resolution tracking and analysis of both nitrogen sources and sinks using a manuresheds-based framework, which identifies areas of nutrient surplus (sources) and deficit (sinks) within agricultural landscapes. By synthesizing these data streams, we are developing a targeted strategy for producing nitrogen-based fertilizers from waste sources, particularly at Wastewater Treatment Plants (WWTPs) and Concentrated Animal Feed Operations (CAFOs) as part of the NSF-funded CASFER Eng. Res. Center. Our approach supports optimized fertilizer distribution aligned with local demand and environmental constraints, ultimately reducing nutrient leakage into watersheds and the environment. This work demonstrates how geospatiotemporal data can drive sustainable innovation at the intersection of agriculture, water quality, and circular nitrogen economies.
