The Agricultural Conservation Planning Framework Financial and Nutrient Reduction Tool (ACPF FiNRT) is an ACPF-compatible tool that provides information about estimated costs and nitrate reduction outcomes from ACPF-generated conservation scenarios.

The use of this ACPF-compatible tool offers conservation planners the ability to examine opportunities and tradeoffs regarding BMPs more effectively on the landscape and offers information about potential outcomes from various conservation scenarios.

The tool is currently available in its beta version for Iowa and Minnesota. In addition to the toolbox, users may also download demo watersheds to try the tool.
