Interpretive Summary: A comprehensive framework for analyzing agricultural nutrient balances across multiple spatial scales (county, HUC8, HUC2) with integration of wastewater treatment plant (WWTP) effluent loads for both nitrogen and phosphorus. Supports classification of spatial units as nutrient sources, sinks, or balanced areas based on agricultural surplus and deficit calculations. Includes visualization tools, spatial transition probability analysis, and nutrient flow network mapping.

Technical Abstract: A comprehensive framework for analyzing agricultural nutrient balances across multiple spatial scales (county, HUC8, HUC2) with integration of wastewater treatment plant (WWTP) effluent loads for both nitrogen and phosphorus. Supports classification of spatial units as nutrient sources, sinks, or balanced areas based on agricultural surplus and deficit calculations. Includes visualization tools, spatial transition probability analysis, and nutrient flow network mapping. Built-in datasets include agricultural nutrient balance data from the Nutrient Use Geographic Information System (NuGIS; The Fertilizer Institute and Plant Nutrition Canada, 1987-2016) and U.S. Environmental Protection Agency (EPA) wastewater discharge data from the ECHO Discharge Monitoring Report (DMR) Loading Tool (2007-2016) . Data are downloaded on demand from the Open Science Framework (OSF) repository to minimize package size while maintaining full functionality, (Akanbi et al. 2024) . Designed for nutrient management planning, environmental analysis, and circular economy research at watershed/administrative to national scales.
