What defines a trained fertilizer applicator?

A trained fertilizer applicator is defined by the requirement to apply fertilizer under certified applicator supervision. This means that the applicator has received specific training and education about safe and effective fertilizer application practices, ensuring adherence to regulations and best practices. By working under the supervision of a certified applicator, the trained individual benefits from the experience and knowledge of the supervisor, which enhances safety, compliance with local laws, and environmental protection.

While applying fertilizer independently or possessing a state license may contribute to an applicator's qualifications, these aspects do not encompass the necessary training and guidance that supervision provides. The option concerning the exclusive use of organic fertilizers does not address the broader training and certification that characterizes a qualified fertilizer applicator. Thus, under supervision ensures that applicators are adequately informed and responsibly carry out their duties while following established guidelines.
