The Annualized AGricultural Non-Point Source (AnnAGNPS) watershed pollution model

A partnership between the US Department of Agriculture (USDA) – Agricultural Research Service (ARS) and the USDA – Natural Resources Conservation Service (NRCS) lead to the development of the AnnAGNPS watershed pollution model. This technology is designed to improve water quality in agricultural watersheds by quantifying the effect of conservation and farming practices on soil loss and water quality. The AnnAGNPS model contains tools to evaluate the integrated effect of conservation practices, locally, where practices are implemented, and at the watershed scale.

MTSU, in partnership with USDA-ARS, is contributing to the on-going development, maintenance, and distribution of the AnnAGNPS watershed model and support tools. MTSU works closely with our partners at USDA-ARS to provide scientific support through research, enhancement, development, and training of AnnAGNPS technologies, such as GIS tools to improve characterization of watershed features and input database generation, and creation of training material.
