applicator fertilizing turf

‘Tis the Season, the Nitrogen Restricted Season (June 1st – Sept 30th)

June 1st starts the Nitrogen restrictive season.  No nitrogen applications allowed until September 30th please see the Manatee County Fertilizer Ordinance for more information.

Fertilizer Analysis on label

Fertilizer Analysis – Nitrogen is listed first, then Phosphorus, and last Potassium

Applications of fertilizer that has an analysis (N-P-K) on the bag must be 0-0-#, this means fertilizer can only contain potassium (K) and other minor nutrients.  Phosphorus (P) is restricted year round and nitrogen (N) is restricted in the summer rainy season.

Other Fertilizer Ordinance requirements in all seasons:
  • Grass clippings must be swept or blown back onto turfgrass. Do not leave grass clippings on hard surfaces.  This helps reduce nutrients that are in grass clippings from entering bodies of water and encouraging algal blooms.
  • No phosphorus applications unless soil testing shows a deficiency and is placed on file with the Manatee County Administrators office.
  • All fertilizer applicators must obtain a fertilizer license, the Limited Certification for Urban Landscape Fertilizer Application under s. 482.1562 Florida Statutes. Register here for upcoming classes.
  • All landscape maintenance employees must receive county or Best Management Practices training.  Register here for upcoming classes.
  • Any fertilizer applied/spilled/deposited on impervious surfaces must be immediately removed.
  • This is voluntary for all of Manatee County. Manatee County recommends a 6-foot low-maintenance zone from any pond, stream, watercourse, lake or canal or any designated wetland.

    Deflector shield to divert fertilizer

    Deflector shield to keep fertilizer applications off of hard surfaces and out of bodies of water

  • Broadcast spreaders must be equipped with deflector shields. Deflector shields must be positioned so that fertilizer granules are deflected away from all impervious surfaces, fertilizer-free zones, water bodies, and wetlands. The ordinance requires a deflector shield within 3 feet of any water body or wetland.
