NJ Fertilizer Law – How It Applies To You

In 2011, New Jersey enacted a new law that governs the application of phosphorus and nitrogen fertilizer in the state of New Jersey.

This law applies to both homeowners and landscape contractors.

This law is meant to reduce the high levels of eutrophication currently affecting the quality of many our coastal and fresh water bodies.

Limitations on Fertilizer Use

Currently, phosphorus may not be applied unless a soil analysis indicates a deficiency. Nitrogen is restricted to per application and total season amounts, of which a minimum of 20% must be slow-release, meaning water insoluble.

These regulations also require certification and training for commercial landscapers. All of our staff are either certified or trained as required by the 2011 New Jersey Fertilizer law.

The law also creates “black-out” periods for both homeowners and contractors when neither nitrogen nor phosphorus may be applied. The black-out dates typically fall into the following timeframes:

  • Homeowners: November 15 – March 1
  • Commercial applicators: December 1 – March 1
