The ManureMap ArcGIS Toolbox is a spatial modeling tool developed by USDA ARS and the ACPF National Hub to map and quantify the application of manure nutrients from animal feeding operations to cropland based on crop nutrient needs. It uses high‑resolution field boundary and land use data in the ACPF format, along with feedlot nutrient availability data, to simulate manure allocation either across a crop rotation or one year at a time (allowing tracking of residual nitrogen). The toolbox supports nitrogen‑based or phosphorus‑based application rates derived from nutrient removal or fertilizer recommendations. It provides detailed lookup tables, yield estimation tools, and outputs summarizing nutrient loads, application acreage, nutrient balances, and spatial distribution. Results are intended for regional nutrient budgeting and planning, not for replacing site‑specific nutrient management plans, and require careful interpretation to avoid misrepresentation of manure’s role in agricultural systems.

_{ACPF HUB is supported through Cooperative Agreement # NR213A750008C007 with the USDA Natural Resources Conservation Service. Funding for the development of new tools and capabilities for the ACPF is provided, in part, by the USDA Natural Resource Conservation Service (NRCS) Conservation Effects Assessment Project- Watershed Assessment Studies under the ACPF Enhancement Project, NRCS Interagency Agreement # NRC21IRA0010883 with USDA ARS.}
