An Act regulating the use of fertilizer in the town of Wellfleet

194th Legislature (2025-2026) Introduced by Hadley Luddy

Wellfleet would ban applying nitrogen or phosphorus fertilizers to protect water quality, with limited exemptions for commercial agriculture and low-nitrogen organic home use.

Summary of Bill HD 6137 (Session 194th) – Massachusetts

Purpose and intent

The bill seeks to protect water quality in the Town of Wellfleet by prohibiting the application of fertilizers containing nitrogen and phosphorus.

It is presented as a measure grounded in scientific evidence linking nitrogen and phosphorus in fertilizers to degradation of local waters, which can affect public health, shellfishing, drinking water, and recreational activities.

The intent is to help Wellfleet meet statewide water-quality standards and TMDL (Total Maximum Daily Load) targets for nitrogen and phosphorus.

Key provisions and changes

Section 1: Establishes that nitrogen and phosphorus in fertilizers can contaminate both fresh and saltwater when used excessively, leading to undesirable algae and aquatic plant growth. Such growth can degrade waters used for drinking, shellfishing, swimming, and boating.

Section 2: Prohibits fertilizer applications that contain nitrogen and phosphorus in order to improve Wellfleet’s water quality. Acknowledges Wellfleet’s unique sandy soils with rapid infiltration and leaching, necessitating stricter controls to meet TMDLs for nitrogen and phosphorus.

Section 3: Overrides conflicting general or special laws to grant local authority for this prohibition in Wellfleet. Specifies that fertilizer containing nitrogen or phosphorus (or other pollutants) cannot be applied in Wellfleet, with two narrow exceptions:

Commercial agricultural use of fertilizers is exempted.
Residential use of organic fertilizer with low nitrogen and phosphorus content for growing fruits and vegetables is exempted.

Who/what would be affected

Targeted jurisdiction: Town of Wellfleet, Massachusetts.

Prohibited activities: Application of fertilizer containing nitrogen or phosphorus (except as noted in exemptions).

Exemptions:

Commercial agricultural fertilizer applications (likely on farms outside the home garden context).
Residential use of organic fertilizer that is low in nitrogen and phosphorus, specifically for growing fruits and vegetables.

Potential indirect effects:

Local lawn/garden practices may shift toward organic, low-nutrient alternatives.
Agricultural operators in Wellfleet may need to adjust practices to qualify for exemptions or to comply with new standard.

Procedural and timeline aspects

The bill is filed as House Docket No. 6137, dated May 13, 2026.

It is framed as “An Act regulating the use of fertilizer in the town of Wellfleet.”

The text does not specify a phased effective date or enforcement timeline; it establishes the prohibition and exemptions, with the implicit assumption of standard regulatory enactment once passed into law.

The measure explicitly states that it supersedes conflicting laws within its scope to authorize local regulation in Wellfleet.

Notes for readers

The bill emphasizes Wellfleet’s unique soil conditions (coarse, sandy, with rapid percolation and leaching) as a rationale for stricter local fertilizer controls.

It references adherence to the Commonwealth’s Total Maximum Daily Loads (TMDL) framework for nitrogen and phosphorus to protect water quality.

If enacted, the regulation would be a localized environmental control rather than a statewide fertilizer policy, with enforcement and penalties to be determined by the implementing authority after passage.
