Nitrogen certification is an educational requirement to encourage the best application of nitrogen fertilizer. Areas requiring certification are identified on the below map.

The District requires educational certification for persons engaged in the use, application and storage of nitrogen fertilizers. Persons required to complete the nitrogen management certification are those that make the nitrogen management decisions on the land to be fertilized to include but not limited to:

• operators of agricultural lands who fertilize 20 acres or more
• farm managers
• commercial applicators
• operators of lawn service companies
• operators of golf courses
• operators of sod farms
• anyone engaged in the application of manure/bio-solids/bio-liquids on five acres

The next certification period will be Spring 2027. Those requiring certification will be contacted prior to that period.
