Strong Fertilizer Ordinances in Florida

Fertilizer Ordinances are considered "low hanging fruit" when it comes to addressing the problem of nutrient pollution in Florida's waterways. So many solutions will take time, policy changes, and money to implement. But fertilizer ordinances cost very little to implement and can reduce nitrates in our waters immediately.

The backbone of a strong fertilizer ordinance includes a summer rainy season ban on nitrogen and phosphorus application, often June through September. During the rainy season in Florida, fertilizer does not have an opportunity to be absorbed into the soil before our frequent rainstorms wash the fertilizer off lawns and into the aquifer and springs, where it fuels algae growth.
