A fertilizer is any substance, including fertilizer material, mixed fertilizer, specialty fertilizer and bulk fertilizer, containing one or more recognized plant nutrients which is used for its plant nutrient content and which is designed for use or claimed to have value in promoting plant growth, except unmanipulated animal and vegetable manure, agricultural liming materials, wood ashes, and other exempted materials.

A specialty fertilizer is a fertilizer distributed for non-farm use and fertilizer material primarily intended to supply plant nutrients other than nitrogen, phosphate, and soluble potash.

Multi-purpose products intended to supply plant nutrients, soil/plant amendments and/or liming materials must be labeled, licensed and registered (as required) under each respective law prior to being offered for sale, sold or distributed in Pennsylvania.

Specialty fertilizer products are regulated through the product registration to ensure consumer safety and efficacy.

Agricultural and specialty fertilizer samples are collected and analyzed to ensure products are currently registered (if specialty fertilizers), meet labeling requirements and are not adulterated.

Turf Fertilizer

The Fertilizer Law of 2022 places nutrient restrictions on Fertilizers labeled for use on turf.  Phosphorus is prohibited in turf fertilizers, unless the product is an organic based fertilizer or the product is labeled as a starter fertilizer or to repair a turf area.  If a slow release claim is made on nitrogen, then it must contain at least 20% enhanced efficiency nitrogen.

Applicators of fertilizer may not apply more than 0.7 pounds of nitrogen or 0.9 pounds of total nitrogen per 1000 square feet.  Furthermore, applicators may not apply phosphorus to turf, unless establishing turf for the first time, repairing a turf area, or applying a phosphorus product that contains enhanced efficiency phosphorus or natural organic phosphorus source and the application rate does not exceed 0.25 pounds of phosphorus per 1000 square feet.  These rate restrictions do not apply in situations where the applicator is following the requirements of a site-specific plan.

    Pennsylvania manufacturers and all guarantors (the name and address that appears on the label of the product) are required to be licensed.
