Nitrogen Certification Training

The Upper Elkhorn Natural Resources District has monitored groundwater quality in the District since 1974. Since this time, the Natural Resources District has expanded its monitoring program to include approximately 600 irrigation wells. This monitoring program along with additional research programs has identified a widespread nitrate contamination problem in groundwater within the District.

Following the Upper Elkhorn NRD Groundwater Management Plan Rules and Regulations, anyone applying nitrogen fertilizer on an area larger than one acre, and using more than 50 pounds per acre of actual nitrogen on any crop, must be certified by the Upper Elkhorn NRD once every four years.

If you are responsible for any applications of nitrogen fertilizer within the Natural Resources District, either commercially or privately, The certification requirement will include attending an educational class or passing a written take home test established by the District to provide and assure quality groundwater. An online test is also available through the UNL Extension. The online practice is made up of training videos and quizzes. There is a test-out option as well.
