Comprehensive Nutrient Management Plan (CNMP) - Information for NRCS Employees and Technical Service Providers (TSP)

Last Modified: 10/21/2008 09:29 AM

Preparing a CNMP can be a simple or complex process, depending on the size and complexity of the animal operation. It typically requires knowledge in engineering, agronomy and crop nutrient management, erosion control practices, irrigation systems, and water management in order to adequately assess and manage water and manure associated with animal feeding operations, and control runoff. Producers may find it necessary to enlist the help of one or more technical experts when preparing a CNMP. A certification program has been established for persons offering to prepare CNMPs to assure certain standards are met.

Not all CNMPs will require the same level of expertise. In some cases, particularly for AFOs that have no plans to add new facilities or expand existing ones, it is possible the CNMP may be prepared by the producer and reviewed by a certified specialist. Producers will need to obtain a minimum level of training to prepare their own CNMPs, possibly through the CDQAP environmental stewardship program.

Obtaining Certification to Prepare CNMP for NRCS

There are four areas of certification required to prepare a CNMP: (1) evaluation of facilities and equipment for handling and storage of manure and storm water, (2) nutrient management for land application of manure, (3) runoff and erosion control from land, and (4) conservation planning. Although one person could obtain all four certifications, it is more typical for CNMPs to be developed with a multi-disciplinary team of specialists (e.g. an engineer, agronomist and planner).

CNMP Implementation

The following documents describe technical requirements for receiving Environmental Quality Incentives Program (EQIP) cost-share for nutrient management. This is intended to be part of a larger plan that includes all engineered improvements on the dairy and cropland needed to adequately manage manure, as appropriate for the producer.

The file AFO Manure Nutrient Management describes required activities. The file AFO Nutrient Management Procedures provides detailed procedures to be used when implementing this practice for cost-share. Please download and review both files.

The following documents are tools to assist producers or consultants to implement CNMP planning or implementation:
