About
Charge
The Agricultural Modeling Team (AMT) will provide agricultural modeling assistance to support the Agriculture Workgroup (AgWG) through the development of the Phase 7 (WSM) inputs.
Functions
Support will be accomplished by providing the capacity for in-depth analyses of agricultural items of interest brought forward by the partnership. From these in-depth analyses, technical decisions will be made regarding the processing of input data in the Phase 7 WSM. The functions of the group will be to:
- Review data preprocessing methods and agricultural inputs to ensure that Phase 7 WSM utilizes the best available information to reflect agricultural conditions in the watershed and how they change through time.
- Review current [Phase 6] WSM assumptions related to the applications of nutrients on agricultural lands and determine if changes are appropriate for Phase 7. Several examples of relevant topics include: manure and fertilizer nutrient inputs; legume fixation; crop application goals; cover-factors for RUSLE*; changing environmental conditions; and soil phosphorus data.
- Consideration of land use/load source category changes.
- Coordinate with USDA agencies to identify supporting model structures, analysis methods and agricultural databases.
- Make decisions on what the most appropriate agricultural input data are for the Phase 7 WSM.
