  1. Potential of Using Precision Agricultural Practices for P Fertilizer Management

  2. Animal Manure Application to Agricultural Lands • Animal Manure is added to Agricultural lands as a Nitrogen Fertilizer Source • After Many Years of Application of Manure on a Nitrogen content Basis, Phosphorous Builds up in the Soil

  3. Water Quality Concerns • Eutrophication • Algal Blooms • Fish Kills • Poor Quality Water • Pfiesteria • Toxic Dinoflagellate • Lesions on Fish • Can be Harmful to Human Health

  4. Algae Bloom

  5. Phosphorous • Phosphorous is an Immobile Nutrient. • Yet, at High Soil Test P levels there can be soluble P in Run off. • Also, Erosion of Soil Containing High Levels of Phosphorous can Result in the Release of soil P to a Water Body

  6. How can Precision Agriculture Practices be Useful • Need to Know how much Phosphorous is reaching Sensitive Water Bodies • Will Phosphorous dissolve in water body

  7. How can Precision Agriculture Practices be Useful • Geographic Information Systems can be used to Determine the Impact High Soil Phosphorous in a Field will have on Sensitive Water Bodies

  8. How can Precision Agriculture Practices be Useful • Soil Data • Soil Test P • Erodability • Phosphorous Adsorption Capacity • Cropping System • Pasture vs. Row Crop

  9. How can Precision Agriculture Practices be Useful • Landscape Position • Distance from Water Body • Slope • Drainage Patterns • Management Practices • Timing and Frequency of Manure Application • Buffer stripes

  10. How can Precision Agriculture Practices be Useful • Information on Water Bodies • Are the Water Bodies Sensitive to Phosphorous addition. • If so, How Sensitive • Maximum Daily loads

  11. Conclusion Soil and Manure Transport Water Body
