OUR APPROACH
1. Identify project area suitability
2. Develop infrastructure for water quality monitoring
3. Build a watershed model
4. Prioritize farmer outreach
5. Estimate field- and farm-scale conservation performance
6. Pay participating farmers for reductions from field baselines

DEVELOP MONITORING INFRASTRUCTURE
Key considerations:
• Location in watershed
• Instream vs. field-edge
• Fixed-interval vs. event-based
• Minimum WQ parameters
− Base flow
− Sediment (TSS & TDS)
− Total & dissolved reactive P
− Total N & compounds
• Startup/ongoing support
• Frequency of analysis

BUILD A WATERSHED MODEL
• Digital Elevation Model
• Land use
• Soils
• Weather
• Management practices (e.g. crop, fertilizer, tillage)
• Reservoirs and outlet(s)
• Point source loads
• Monitoring station data

Where are agricultural P losses concentrated?
Are watershed or farmer-led groups active there?
Which reduction activities would be cost-effective?
PRIORITIZE FARMER OUTREACH

ESTIMATE FIELD/FARM-SCALE PERFORMANCE
Process-based watershed simulation model that can:• Route water, sediment, nutrients, and pesticides at any user-defined scale• Assess environmental effects of implementing a broad range of
agronomic and structural practices• Integrate with SWAT and the Farm Economic Model• Be used as a web interface (NTT) in ~13 states

ESTIMATE FIELD/FARM-SCALE PERFORMANCE
Helps Wisconsin farmers develop agency-compliant nutrient management plans and calculate:• N-P-K recommendations by crop/field• RUSLE2-based soil loss assessment of which fields meet tolerable soil loss• Annual and rotational PI value for all fields• Rotational P balance based on soil tests• Lbs of P loss reduction for trading (in development)

PUTTING IT ALL TOGETHER• Use watershed-scale models to set the context and prioritize efforts
• Use field-scale tools/models for decision making and incentive payments
• Calibrate models to recent conditions and validate with monitoring data
• New technologies can help streamline field-to-watershed scale conservation programs
BUT
• How long will it take to see change?
• What about social/economic/ecological outcomes?
