Slide 1: Nutrient Management Plans Rick Kerbsbergen Waldo County UMCE
Slide 2: Plan Outline: Page 1 Pg 1: Basic Farm information Contacts for rented acreage Number of animal units on annual basis  one A.U. = 1,000 lbs of wt.  200 cows @1350 plus 125 heifers @650 = 351 A.U. Maps of all fields and sensitive areas, including soil type and slope
Slide 3: Plan Outline: Page 2 Farm plan summary sheet Includes  Permanent field names  Crop rotations  Data concerning planned nutrient sources and last soil test date
Slide 4: Plan Outline, Page 3 Listing of Environmental factors  lake watershed, sand/gravel aquifer etc.. Plans for the future (recertification)  change in land base (up or down) by 15%  increase in 50 A.U. on annual basis
Slide 5: Whole Farm Budgets  Answers the question: “Is your land base adequate to handle the manure from your animals?”  Calculate total manure produced  Use manure analysis to determine plant available nutrients: PAN and PAP2O5  Determine crop needs and decide if manure nutrients exceed crop requirements
Slide 6: Plan Outline: Page 3  From manure analysis…..  PAN = 50% *lbs NH4-N + 54% *lbs organic N  PAP2O5 = 90% * lbs P2O5  Manure production based on A.U.  15 gallons/A.U. or 92 lbs/A.U. (dairy)  Volume (gallons or lbs) *PAN (per ton or 1000 gal) = total amt of PAN or PAP2O5
Slide 7: Calculating Crop Needs Use crop removal rates on page 6 of guidance to determine crop needs If crop needs exceed manure nutrients, you have adequate land base If manure nutrients exceed crop requirements, you do not have an adequate land base and may need to look for export options
Slide 8: Plan Outline: Page 4 Manure summary sheet Manure test results Export information  where manure will be going Import information  biosolids, poultry manure, non-regulated materials
Slide 9: Plan Outline: Page 5 Manure storage issues on your farm Law requires producers to demonstrate they have ability to store manure for 180 days Stacking sites (manure >18% dry matter)  NRCS approved or producer identified using criteria on page 7 of guidance Constructed facilities (engineered)
Slide 10: Plan Outline: Page 5 Every plan must contain provisions for odor and insect control related to manure spreading and storage Listing of BMP’s to select from on Pages 9 and 10 in guidance document If there are verified complaints, producer could be asked to implement additional BMP’s
Slide 11: Plan Outline: Page 6  Requires:  erosion control  spreading setbacks  soil tests and nutrient balance for each field (fields can be grouped for nutrient balance)  Erosion control--NRCS, FSA HeL, or producer developed (pg. 11 guidance)  Spreading setbacks--site specific (pg 13-15)
Slide 12: Plan Outline: Page 6  Limiting nutrient  Nitrogen or Phosphorus?  Matrix helps you determine (pgs 17-18)  Rates of application will depend on N conservation factors and mineralization rates if using an N budget (pgs 20-21)  Field plans should also include planned timing of applications, antic. incorp. times, plowdown credits and mineralization rates
Slide 13: Recordkeeping is Important.. Document when and how much manure was applied Indicate why applications may be different than from original plan
Slide 14: Plan Certification All plans must be certified by someone who has passed a certification test  Producers can write own plan--get it certified by someone with commercial status  Producers can write and certify own plan with private license  Plans are considered confidential business information
Slide 15: Taking the Test... Review the law in Chapter 8 Review competencies in front of the book Read the question well and all the answers!
