Indiana law requires fertilizer applicators to become certified. Commercial applicators of agricultural fertilizers, as well as individual applicators of manure from confined feeding operations (CFOs), are subject to this legislation. This manual assists those seeking certification to prepare for the Category 14 certification examination.
