Supervision of Non-Certified Fertilizer Applicators


All for-hire fertilizer use (application, handling, transporting) and all use of manure from a Confined Fertilizer Operation (CFO) must be performed by certified and licensed applicators or by trained employees working under the direct supervision of a certified and licensed supervisor.

Direct supervision of non-certified fertilizer applicators may be accomplished by the certified applicator:

  1. Ensuring the non-certified employee has received OISC-approved training.
