Comprehensive Nutrient Management Plans(CNMPs)

• Fred Kelly
• USDA Natural Resources Conservation Service

2
CNMPs

• Required by USDA - EPA Unified Animal Feeding
  Operation (AFO) Policy 1999
• In concert with NRCS Nutrient Management Policy
  effective May, 2001
• For operations that collect, store, and spread
  animal waste

3
CNMP Basic Elements

• 1. Waste handling and storage
• 2. Nutrient management
• 3. Land treatment practices
• 4. Feed management
• 5. Other utilization activities
• 6. Recordkeeping
• 7. Emergency management

4
Manure Storage and Handling

• Animal types, numbers, waste amounts
  generated
• Storage type and size
• Yard management
• Distribution mechanism
• Operation and maintenance

5
Nutrient Management

• Nutrient content of waste analysis or book
  values
• Soil test results
• Crop rotation and nutrient needs
• Available land spreading rate
• Additional fertilityapplication rate
• Phosphorous and Leaching Index

6
Phosphorous Index

• Designed to estimate risk of phosphorous runoff
  to surface waters
• Weighted ranking using
• 1. Soil erosion
• 2. Runoff class (soil and slope)
• 3. Soil test P
• 4. Distance to surface waters
• 5. Method of P application
• Result helps planner advise on whether the
  nutrient mgt. plan is based on nitrogen or
  phosphorous

7
Leaching Index

• Designed to estimate risk of nitrogen leaching
  below the root zone to ground water.
• Uses
• 1. Nitrogen application method and timing
• 2. Soil texture
• 3. General temperature and rainfall data
• Result helps planner advise on basic practices
  to reduce risk of N leaching

8
Land Treatment Practices

• The field conservation practices to be installed
  and maintained to protect water quality.
• Contained in the attached conservation plan and
  schedule
• Typical crop rotation, crop residue management,
  filter strip, terrace

9
Feed Management

• Addresses feed and how rations impact nutrient
  content of waste
• Goal reduce phosphorous feed content and feed
  waste
• Handled by Extension or consultant

10
Other Utilization Activities

• Uses for waste outside of farm operation, or for
  purposes other than soil fertility
• Distribution to other properties
• Processing and marketing
• Energy generation

11
Recordkeeping

• Required for the producer
• Document the waste distribution variables
• Tract, field, date, weather, amount, crop, yield,
  soil test, manure test, other fertilizer

12
Emergency Response

• Contact information for local emergency and
  health officials-
• in case of a spill or release of waste
• Action plan to contain and clean up spills
• Safety
