Nutrient Best Management Practices

Current News

Agricultural producers as well as turf and landscape practitioners in the Commonwealth of Massachusetts are advised to stay up to date with changing nutrient management requirements in the state.

Chapter 262 of the Acts of 2012 authorized the enactment of new statewide nutrient management regulations by the Massachusetts Department of Agriculture (MDAR). The text of the enabling legislation can be found at:

Chapter 262 requires MDAR to ensure that subsequent regulations relative to plant nutrients are consistent with UMass Extension’s published information, educational materials and other public outreach programs relative to nutrient management and fertilizer. UMass Extension in 2013 conducted a thorough review of the body of available technical information in regard to nutrients and fertilizers to verify that all published standards were sound and up-to-date.  Nutrient management information compiled in conjunction with this review can be found below under the 'UMass Extension Nutrient Best Management Practices' heading.

In response to the enabling legislation, MDAR developed and wrote regulation 330 CMR 31.00: Plant Nutrient Application Requirements for Agricultural Land and Land Not Used for Agricultural Purposes. The regulation gives MDAR state-wide authority to regulate and enforce the registration and application of plant nutrients including, but not limited to, fertilizer, manure and micronutrients.  The Cape Cod Commission, Martha’s Vineyard Commission, and Nantucket Commission have the option to adopt their own ordinances in regard to nutrients and fertilizers, but they cannot be less restrictive than the state regulation. Current statutes on Cape Cod, Martha's Vineyard and Nantucket contain exemptions for production agriculture, so agricultural producers in these locations are subject to the state-wide regulation.

Nutrient regulations in process as of October 2014:


  • Massachusetts state-wide regulation (330 CMR 31.00): Proposed regulation has been released and public hearings have been completed.

UMass Extension Nutrient Best Management Practices

Through thoughtful nutrient management planning and the implementation of appropriate best management practices (BMPs), agricultural producers, land and property managers and others can manage farming operations and the properties under their care profitably and with protection of natural resources, particularly water, as a priority. The following are UMass Amherst Extension resources intended to provide practitioners and others involved in the management of soil fertility and plant nutrients with sound, up-to-date technical information.
