The Agricultural Conservation Planning Framework Financial and Nutrient Reduction Tool: A planning tool for cost effective conservation

The paper introduces the Agricultural Conservation Planning Framework Financial and Nutrient Reduction Tool (ACPF FiNRT), an add-on to the ACPF that enables combined spatial and financial analysis of best management practice (BMP) scenarios for nutrient reduction in agricultural watersheds. The tool estimates total long-term annualized costs and nitrogen (N) loss reductions for multiple BMPs at the field and watershed scales, accounting for both direct costs and spatially explicit opportunity costs derived from crop productivity indices and land rent data in Iowa and Minnesota. Demonstration case studies show that targeted combinations of BMPs can achieve substantial N load reductions at much lower total and per-unit costs compared to non-targeted applications, such as universal cover crops. The ACPF FiNRT empowers planners and landowners to develop cost-effective, data-driven conservation plans tailored to local watershed priorities and available resources.
