1. Introduction to Nutrient Management Planning What is a Nutrient Management Plan? &Why Prepare a Nutrient Management Plan? University of Wisconsin - Extension UW-Madison College of Agricultural & Life Sciences

2. Nutrient management Combines on-farm nutrient sources, with commercial fertilizer, to meet crop need On-farm nutrient sources (manure and legumes) Commercial fertilizer Minimize nutrient losses

3. Nutrient management strategy Measure current soil fertility levels Determine crop nutrient needs Account for on-farm nutrient sources Manure applications Legumes in crop rotation Residual soil nitrate Adjust commercial fertilizer application rates

4. Nutrient management economics Deliberate management decisions; how to meet crop nutrient needs across the whole farm. Best use of commercial fertilizer, manure and legume N products – amounts – timings, etc. Account for and properly use on-farm nutrients: Credit N-P-K in livestock manure applications, Credit N from rotated legume crops. Best use and allocation of nutrient dollars ($$$) for profitable crop production.

6. Alfalfa N = $ 3,960

7. (100 acres/yr @ 90 lbs N/a)

8. Manure N = $ 3,564

9. (27 tons/cow/year @ 3 lbs N/ton)

10. Manure K2O = $ 7,371

11. (27 tons/cow/year @ 7 lbs K2O/ton)

13. Sources of nutrients thatcan enter groundwaterand surface water Natural background levels (<2 ppm nitrate-N) Septic systems Urban fertilizer use Municipal and industrial discharge Agricultural nutrient use Commercial fertilizer Manure, legumes, & others

14. Regulatory reasons for nutrient management plans USDA - Nutrient Management Standard (590) WDATCP Cost-sharing & Farmland Preservation Program USDA - NRCS EQIP & CSP Programs NR 243 WPDES Permits Notice Of Discharge (NOD) EPA / USDA / WDNR – 303(d) Listed Waters (TMDL) Program Local Ordinances

15. Nutrient management planbasic components Soil Test Reports Manure Inventory Nutrient Crediting Manure, Legumes, Other (sludge, whey, etc.) Manure Spreading Plan Soil Conservation Plan

17. Waterways

18. Frozen or snow-covered ground restrictions:

19. Within 1000 ft of lake, pond, or flowage

20. Within 300 ft of river or stream

21. 200 ft uphill of direct groundwater conduits

22. - wells, sinkholes, fractured bedrock, etc.

24. Explain manure application restrictions

25. - No winter spreading

26. - Critical areas

27. - Surface water setbacks

28. Verify farms ability to utilize produced manure

29. - Available land, manure spreading agreements, etc

32. Who to contact for assistance and information County UW-Extension Office County Land Conservation Departments WI Technical Colleges Private Crop Consultants Nutrient and Pest Management Program (http://ipcm.wisc.edu/) UW-Discovery Farms Program (http://uwdiscoveryfarms.org)

33. Nutrient Management Implement the plan A nutrient management plan, on paper or contained within a computer program, is only the beginning. Nutrient management needs to make sense and be practical enough that producers will put it into practice on their land – within their farm operation.
