Nutrient Management

The NRCS has developed the tools below to aid in the development of Nutrient Management Plans (NMP) and Comprehensive Nutrient Management Plans (CNMP). These tools are for your use. 

The following files require  Microsoft Excel, Adobe Acrobat or Microsoft Word.

Plan Outline Narratives

There are three narratives below that you can use as an outline for the creation of these plans. These are written to comply with the 590 Standard. There are red letter prompts in each narrative where you can insert individual plan specific information. These narratives can be used as the planning document typically followed by an appendix of the inventories, maps and nutrient budgets.

• CNMP Narrative with Emergency Action Plan
• Example Nutrient Management Plan   
• NMP Narrative – Without Livestock
• NMP Narrative – With Livestock

Iowa Phosphorus Index

Iowa NRCS and Iowa State University has developed an Iowa Phosphorus Index (PI). The Iowa PI is an assessment tool for the purpose of evaluating the potential of off site phosphorus movement. This Iowa PI is to be used when a NMP is being developed based on the 590 Standard and one of the following conditions exist: 1. When manure is applied. 2. Soil loss is above the tolerable level (T). 3. The planning area is within an identified nutrient impaired watershed. 4. The soil test phosphorus levels are above optimum.

• The Iowa Phosphorus Index Calculator (4.6 MB) (To save this file, right click on the link, save target as..., name and save file where desired, open the file where saved.)
• Phosphorus Index Fact Sheet  

Checklists

Iowa NRCS has developed two checklists for your use. These check lists should be used as a final check as to the completeness of the NMP.

• NMP Checklist    3/17/08
• CNMP Checklist    3/17/08
• CNMP Fillable Checklist   3/17/08
