Practicing Conservation

Nutrient and Pest Management
The Polk County Land and Water Resources Department (LWRD) will be accepting applications from eligible landowners interested in assistance with developing USDA 590 and/or 595 Standard Certified Nutrient and Pest Management Plans (NPM).  Eligibility is limited to Farmland Preservation Program (FPP) participants located outside DNR NPS Priority Watersheds.  NPM plan development is already cost sharable under some priority watershed programs.  If not in a priority watershed, money may still be available under other programs. 

Funding for 50% of the cost of crop consultant fees for NPM plan development will be available for eligible applicants.  Landowners will be reimbursed up to $3.00 per acre for nutrient management and up to $5.00 per acre for nutrient and pest management plan development annually.  An early sign-up is encouraged so that soil testing and conservation plans can be completed or updated as soon as possible for the crop year.

Contact your crop consultant and determine the number of acres you will need to have planned, then contact the LWRD at (715) 485-8699 to apply.

Conservation Practices

590 Requirements
  1. Farm Aerial Photographs and Maps
    1. Photos indicate current field boundaries and field ID numbers?
    2. Fields with manure spreading restrictions are identified?
  2. Soil Survey Maps
    1. Are soil series and slope consistent with plan?
    2. Soil Test Reports (attached to NM plan)
    3. Are all the soil test reports from an approved lab?
    4. Have all fields been tested within the last four years?
    5. Is the soil sample size 5 acres or less per sample?
    6. Does the soil test field ID correspond with NM plan field ID?
    7. Are yield goals identified? (for P205 and K20 recommendations)
    8. Have the predominant soil series for each field been identified?
  3. Written Plan Components for individual field nutrient recommendations
    1. Crop to be grown and previous crop grown are indicated?
    2. Fertilizer recommendations are indicated?
    3. Legume and manure credits are indicated?
    4. Manure application rates and spreading sites are indicated?
    5. Additional fertilizer needs are indicated?
  4. Are fields receiving manure or organic byproducts less than or equal to "T"?
  5. Farm Information Sheet items for manure quantity and spreader capacity
    1. Animal numbers, average weight, confinement, consistency.
    2. Estimated annual manure production and amount collected.
    3. Type of manure spreading equipment.
Manure Management Tips
  1. Priority locations to apply manure include:
    1. High nitrogen-using crops (second-year corn, grasses)
    2. Fields with low soil test values
    3. Fields low in organic matter
  2. Inject or incorporate manure within 72 hours for maximum N availability and minimum runoff.
  3. If you do not incorporate manure within 72 hours, apply a maximum per acre of:
    1. 8,000 gallons liquid dairy manure
    2. 25 tons solid dairy manure, or
    3. The equivalent of 75 lbs. available P2O5 for other types of manure.
  4. Do not exceed the crop's nitrogen needs by more than 20%.
  5. If soil phosphorus exceeds 150 ppm, discontinue manure applications to the field.
  6. Do not apply manure to:
    1. Areas within the 10-year floodplain, or within 200 feet of streams, unless manure is incorporated.
    2. Frozen or snow-covered grounds where slopes are 12% or greater (D slopes) when residue is managed and strips are in place; or where slopes are 9% or greater if these practices are not used.
    3. Waterways and areas of concentrated water flow unless manure is incorporated.
    4. Soils less than 10 inches thick over bedrock.
  7. On coarse-textured soils restrict fall applications until soil temperature is below 50 degrees.
