A nutrient management plan (NMP) helps farmers make science-based decisions about when, where and how many nutrients to apply to their cropland. A NMP begins with current soil test data to know the baseline of your soil fertility by field. By knowing the soil fertility and the nutrient need for your crop you can calculate how many nutrients (manure and/or commercial fertilizer) to apply to meet your crop need - not too much, not too little but just the right amount. By applying too much fertilizer or applying at the wrong time nutrients may be lost to the air, surface water or groundwater. If you apply too little you may lose yield. The goal is to apply just the right amount to maintain soil fertility, provide enough nutrients for your crop and obtain a good economic yield.

Who needs an NMP
- EVERYONE! All crop producers and livestock producers that apply manure or other nutrients directly to agricultural fields shall comply.
- Since January 1, 2008, all farms are required to have an NMP for their cropland

- Must be submitted by April 1st each year.
