Throughout the Puget Sound region of Northwest Washington, impacted and poorly managed agriculture has repeatedly been advanced as a leading contributor to air and water pollution. Improvements in field application methods and timing are necessary in order to protect important resources from further negative impacts. This study aimed to develop an innovative Application Risk Management (ARM) System that targets the transport of manure nutrients (N, P) and fecal coliform (FC) via runoff, leaching, and/or volatilization by promoting science-based assessment tools linked to measurable outcomes.

  2. 2. CommunitiesShellfishLivestockDairySalmonResourceConcernsPugetSoundFeedCropsSpecialtyCrops Diverse Agriculture:Livestock and Crops Impacted Resources:Surface and GroundWater
  3. 3. ShellfishSalmonWhatcom County, Washington 125 Dairies; 56,000 milk cows 70% North America raspberryproduction 80,000 acres of crop land Impacted resources 40-8o” annual precipNaturalResourcesCrop -BerryLivestock -Dairy
  4. 4.  Pollutant availability Variable uptake and/or conversion (N, P, FC,…) Improper manure application/grazingpractices Timing, method, rates Weather events Precipitation, flooding, high water table, wind Poor field conditions Soil type, slope, surface cover, saturated soils
  5. 5.  Application Risk Management System Real-time Manure Spreading Advisory Dynamic Manure Application Setbacks Guidance and educational support
  6. 6.  EPAWatershed grant: 2010-2014 Four Overlapping Phases: Phase 1 - Assessment Phase 2 - Development Phase 3 - Implementation andMonitoring Phase 4 - Evaluation, Adaptation, andOutreach
  7. 7.  System to address surface runoff, groundwaterleaching, and air emissions in one tool Minimize pollution risk from manure applicationwith effective management tools and education Address risk on a spatial and temporal scale Accountability –Take responsibility for actions Flexibility – Better options when to apply Assist with application during high risk times Integrate ARM into nutrient planning process
  8. 8.  Individual field level risk assessment for runoffand leaching Soil risk rating based on 15+ factors and visualfield assessment Example Risk Levels - Runoff: High – Bare ground, adjacent water, high water table, flooding Med-High – Minimal cover, high water table, ponding Medium – Adjacent water, ponding, good infiltration, low slope Low-Med – Dense cover, low water table, minimal slope Low – Grass, no adjacent water, good infiltration, good AWC

  11. 11.  Evaluating worksheet parameters Field testing system and worksheet Monitoring, assessment, and validation Soil, manure, forage, surface water,groundwater, soil water, air, meteorological
  12. 12.  Evaluating worksheet parameters Field testing system and worksheet Monitoring, assessment, and validation Soil, manure, forage, surfacewater, groundwater, soilwater, air, meteorological Adapt worksheet criteria to specific areas Optimizing manure applicationstrategies and guidance
  13. 13.  Good collaboration between soil, soil water,and groundwater results ARM - Limited fall application tends toreduce fall and spring nitrate leaching ARM – No increased leaching with earlyseason app + reduced runoff probability
  14. 14.  Good collaboration between soil, soil water, andgroundwater results ARM - Limited fall application tends to reducefall and spring nitrate leaching ARM – No increased leaching with early seasonapp + reduced runoff probability Increased first cutting forage yield 30% withearly season application Tools bringing dynamic nature to planning Still work to be done!
  15. 15.  First line of defensein runoff prevention “If risk ishigh, don’t apply” Updated daily fromNOAA forecast Current guidanceand setbacks Optimizing formobile use
  16. 16.  Use correlates withprecipitationpatterns andfarming activity Over 100 pageviews per month
  17. 17.  Use in lieu of filter stripswhere appropriate Based on scientificevaluation and localconsiderations Dynamic distance/datein shoulder seasons Apply to both liquid andsolid manure application
