Model Fertilizer Ordinance for South Florida
Does my area need a fertilizer ordinance? Yes!
Residential lawn fertilization is estimated to be the second largest source of household nitrogen in the US (Souto et al. 2019). Excess nutrients, such as nitrogen and phosphorous, which come in most fertilizers, can pollute waterways and cause environmental problems such as algae blooms. Algae blooms kill wildlife, are harmful to humans, smother seagrass, and turn our beautiful blue water green. Biscayne Bay is already starting to suffer from algae blooms and seagrass die-offs. Therefore, it’s more critical now than ever to reduce land-based pollution. Reducing the use of residential fertilizer can improve our waterways and will help to keep Biscayne Bay blue!
Miami Waterkeeper has developed a sample fertilizer ordinance specifically for South Florida to protect our waterways. This ordinance would limit location, time, and amount of fertilizer that can be applied on South Florida properties.

How could a fertilizer ordinance be enforced?
Fertilizer ordinances should be enforced by the implementing municipality as they would other provisions of municipal code. Miami Waterkeeper compiled some key enforcement suggestions in the memo below, and we recommend that all ordinances also include a strong public education component.
