Comprehensive Nutrient Management Planning (CNMP)

Plan Development Resources and References

Comprehensive Nutrient Management Plans (CNMPs) are conservation plans unique to livestock operations.   These plans document practices and strategies adopted by  livestock operations to address natural resource concerns related to soil erosion, livestock manure and disposal of organic by-products.

The development of a CNMP begins with a comprehensive engineering and conservation planning resource assessment of current site conditions. Management options and structural alternatives are developed to address resource concerns identified during the assessment.

The minimum criteria for developing a CNMP is defined in the NRCS National Planning Procedures Handbook (NPPH), Subpart E (Parts 600.50- 600.54), Subpart F (Part 600.75) and Subpart C – Exhibits (Exhibit 15) at: http://www.nrcs.usda.gov/technical/afo/cnmp_guide_index.html.  Individuals who approve and/or develop CNMPs must be certified by the Wisconsin NRCS or through the TechReg website.

CNMP Success Story
The real value of a CNMP was vividly demonstrated in 2006 on a farm near Hillsboro in Vernon County.   A hose clamp failed as the manure storage structure for the 500-cow herd was being pumped out and applied to the field.  About 4,000 gallons spilled into the field.  The farmer was able to react very quickly and followed the emergency actions outlined in his CNMP.  Due to his quick response, only about 800 gallons may have reached the stream, the South Branch Creek of the Baraboo River in the Hillsboro watershed.  The stream is expected to recover according to Wisconsin Dept. of Natural Resources. 

“We have been working with Discovery Farms over the past year towards completing this CNMP and as a result the recommended actions described in the Emergency Action Plan were really very fresh in my memory,” said the farmer. “Having the list of phone numbers for emergency contacts, contractors, agencies is very useful.  We are having the lists laminated and placing them in several places around the farm,” he said.  “We have several employees who would typically realize what to do in case of emergency, but having the Emergency Action Plan and the contact numbers close by is really necessary if quick action is needed.” 

Due to a recent manure storage expansion, he was required to develop a nutrient management plan to meet Vernon County’s Manure Storage Ordinance. However, he voluntarily chose to develop the complete CNMP to help him better manage his dairy operation.  A fact sheet is available from NRCS, “Why Farmers are Choosing CNMPs” which discusses other reasons to develop a CNMP, including regulations, legal liability, insurance, safety, and improved management.
