Fertilizer certification is required for farmers who apply fertilizer (other than manure) to more than 50 acres of land for agricultural production grown primarily for SALE.  The term “agricultural production” is defined as the cultivation, primarily for SALE, of plants or any parts of plants on more than 50 acres. If you raise forage (e.g., hay, silage, corn) for use on your farm, you don’t need to have a fertilizer certificate to apply fertilizer.  The fertilizer law went into effect September 30, 2017.  Training will be offered every year. Pre registration is required.
