Nutrient Management Standards – Making Them Work Where We Work
Download as PPTX, PDF1 like1,105 views
The document summarizes a panel discussion on nutrient management standards and their implementation in different states. The panel addressed several questions related to how states implement the NRCS 590 nutrient management standard, including what tools they use to assess phosphorus and nitrogen risks, whether they have unique plans for air quality or winter spreading, and what nutrient planning tools producers use. The document concludes by outlining potential research topics related to updating the 590 standard, including improving phosphorus indexing, developing nitrogen leaching assessment tools, providing guidance on air quality planning, and ensuring nutrient management tools meet user needs.

- 17. 1. PHOSPHOROUS INDEX Interpretation and implementation Better determination/definition of low, high, very high, etc. based on Regions Need better area resolution between and within States What is the "no application" rate? In what cases is P not a problem? What about fields without water around? What is threshold? Issues? P leaching? Should we be looking at this in certain climates? Soil types? P analysis methods - not comparable, variable. Need better consistency, guidelines on when to choose which test, and limitations for each test value.
- 18. 2. NITROGEN LEACHING INDEX Few individual State tools, most use RUSLE2 Need to add leaching to evaluation tools Not sure how to evaluate leaching in planning Need BMP options for leaching management - work with NRCS on defining which practices reduce leaching - bundle together Need more science based information on when and how leaching occurs in specific soil types Nutrient Trading? Is this viable? Is it a good idea?
- 19. 3. AIR QUALITY ASSESSMENT AND PLANNING Need Air Quality Management Plan (AQMP) format and guidance Easy to use inventory and evaluation tools for planners Need training of planners to identify AQ concerns and BMPs Prioritize pollutants to address (i.e., dust, ammonia, hydrogen sulfide, etc.) Regional considerations vs. National Air quality vs. climate change - Which do we focus on and why?
- 20. 4. WINTER NUTRIENT APPLICATION Tile drainage Application to snow covered, frozen ground What are impacts to runof f, leaching? More restrictions are anticipated in coming years Storage will become a bigger issue Alternatives to land application of manure? Solid vs. liquid manure application concerns Need to get custom applicators enrolled Integrate the 4 Rs (right source, timing, rate, placement) into nutrient tools, research evaluation, and guidance Digestate: Pros and cons? Manure application setback distances - need more scientific evaluation and consistency in how we make recommendations
- 21. 5. MATCHING THE TOOL WITH THE USER Who is using the tool? Producer or planner? Both? Who should be using tools? Need real-time decision tools Address responsible manure management Apps, web interface, excel? Which has most utility? Need to integrate producers into research as reviewers and testers. Many States have no scientific advisors for issues. Regional solutions? How do we keep planning tools and 590 from becoming regulatory? Create a national committee to look at the best ways to assess these issues and questions.
