News Image

Stormwater runoff is a major source of pollution flowing into our natural waterbodies. Seminole County Public Works Department, Watershed Management Division is proposing a NEW Fertilizer Ordinance to be considered for adoption by the Board of County Commissioners on Tuesday, September 27th at 1:30 pm. This proposed new Fertilizer Ordinance will regulate fertilizers containing nitrogen and/or phosphorous and provide specific management guidelines for fertilizer application in order to minimize negative impacts to our natural waterbodies. The education materials and resources below explain the proposed Ordinance.

Key Highlights of the Proposed Fertilizer Ordinance:

  • Fertilizer containing nitrogen and/or phosphorous cannot be applied to turf during the restricted season from June 1st – September 30th.
  • Fertilizer containing nitrogen that is used during the non-restricted season (October 1st – May 31st) must contain at least 50% slow release nitrogen.
  • Fertilizer containing phosphorus cannot be applied to turf or plants unless a state certified soil or tissue test verifies that there is a phosphorus deficiency. For more information about soil & tissue testing, contact your local UF/IFAS Extension office at 407-665-5560. Click here for more information on Soil & Tissue Testing requirements.
  • Use of deflector shields are required when applying fertilizer if you are using a broadcast or rotary spreader.
  • No fertilizer may be applied within ten (10) feet of any pond, lake, stream, canal, or other waterbody, including wetlands.

The overall goal of this ordinance is to minimize excess fertilizer runoff and protect the County’s natural water resources.
