The Minnesota Nitrogen Fertilizer Management Plan (PDF) is the state's blueprint for preventing or minimizing impacts of nitrogen fertilizer on groundwater.
"The primary goal of the Nitrogen Fertilizer Management Plan is to involve the agricultural community in problem solving at the local level. We all need to work together to respond to and address localized concerns about unsafe levels of nitrate in groundwater."
- Commissioner of Agriculture, Dave Frederickson
There is an extensive body of research documenting fertilizer as source of nitrate in groundwater. Nitrate from nitrogen fertilizer can leach below the root zone and migrate to groundwater. View a list of articles and reports from work done in Nebraska, work done by the United States Geologic Survey and studies from Minnesota. A list of additional references found in subscription journals is also included.
The Minnesota Department of Agriculture developed the original Nitrogen Fertilizer Management Plan in 1990. The Plan went through a revision process from 2010 to 2014. The revised Plan includes new scientific information about groundwater protection and is better aligned with current water resource programs and activities.
The MDA received 32 formal responses. The MDA compiled all written and verbal comments into the following document:
- Public Comment on the August 2013 draft Nitrogen Fertilizer Management Plan (PDF Portfolio: 41.6 MB / 262 pages (37 documents))
The MDA has carefully reviewed all public comments and developed the following two response documents:
- Response to Public Comments on draft Nitrogen Fertilizer Management Plan (PDF)
- Response to Individual Comments on the draft Nitrogen Fertilizer Management Plan (PDF)
The revised NFMP was finalized in March 2015.
