Environmental Standards; Environmental Bans & Restrictions
Lawn Fertilizer Law in Maryland (United States) limits the amount of nutrients that can be applied to lawns or turf by ensuring 20% of the nitrogen is slow release to minimize losses to the environment, requring everyone to apply fertilizer based on recommendations, and restricting application rates, times of the year, and land cover types. It requires lawn care professionals to be licensed and certified by Maryland Department of Agriculture to apply turf fertilizer to properties that they manage or work under the direct supervision of someone who is certified.
Maryland's Lawn Fertilizer Law helps protect the Chesapeake Bay from excess nutrients entering its waters from a wide range of non-agricultural sources, including golf courses, parks, recreation areas, athletic fields, businesses and hundreds, of thousands of urban and suburban lawns.
