Using a watershed nutrient dynamics model, WEND, to address watershed-scale nutrient management challenges.

From: Journal of Soil and Water Conservation | Date: September 22, 1999| Author: | Copyright information

ABSTRACT: Nutrient management has become a major focus for watershed-scale planning to sustain or improve groundwater quality in certain areas. The USDA Natural Resources Conservation Service (NRCS) Watershed Science Institute (WSSI), in cooperation with a number of partners, is developing a process for creating unique, watershed-scale models to examine dynamic phosphorus (P) flows into, out of, and within watersheds using a mass balance approach. The Watershed Ecosystem Nutrient Dynamics (WEND) model tracks watershed P balances over time within each of the several land-use ...
