The Fertilizer, Soil or Plant Additive and Lime (Fertilizer) program protects consumers and businesses against unfair and deceptive practices in the sale of agricultural, household, commercial lawn care, and athletic turf fertilizer, soil or plant additives and agricultural lime and to prevent certain hazards to persons, property, and the environment.

Manufacturers, labelers and distributors of these products are required to be licensed and product labeling must be approved and/or permitted before being distributed into the state. The department inspects fertilizer blending facilities and collects and analyzes samples in order to ensure that the products meet their label guarantees.
