1. (1) Low analysis mixed fertilizer containing less than 5% total primary plant nutrients may be guaranteed in other than whole percentages; however, each primary plant nutrient claimed shall be no less than 0.5%. Ready-to-use spray fertilizer products and potting soils and mulch products for above ground use containing fertilizer, do not require a minimum primary plant nutrient guarantee and may be guaranteed in fractional units.
2. (2) Specialty liquid fertilizer, hydroponic fertilizer, and continuous liquid feed fertilizers containing less than 5% total primary plant nutrients do not require a minimum primary plant nutrient guarantee and may be guaranteed in fractional units.

3. (3) Manipulated manures and compost come within the definition of fertilizer. In addition to the labeling requirements set forth in Section 576.031, F.S., the labels on all manipulated manures and composts shall contain in or in close proximity to the brand name, the common name of the product and the grade numerals in terms of the primary plant nutrients, (unless all three are zero), e.g., “Supreme Compost 1-2-1.”

   1. (a) When the term manure is used in any brand name, labeling, or advertisement identifying any product, the animal source of the manure must also be shown.
   2. (b) Products containing manure mixed or composted with other organic materials shall include the name of the other material in its brand, labeling and advertisement, e.g., “Cattle Manure plus Organic Compost,” “Horse Manure composted with Peat”. The common names of the components of such products shall be listed on the label in order of relative amount in the mixture.
   3. (c) Manures and products containing manure shall be guaranteed to have a minimum of 0.5% total nitrogen, 0.5% available phosphorus and 0.2% soluble potassium. All statements of guarantees or grade numerals less than one percent shall be expressed as decimal fractions, with a zero preceding the decimal.
   4. (d) Guano and earthworm castings are exempt from paragraph (c).
   5. (e) Material recovered from lagoons or holding ponds designed to retain manure run-off is considered to be a compost and may not be claimed, branded or advertised to be a manure, except that the term “manure” can be used in a descriptive manner in a listing of source materials, as in “Derived from Cattle Manure Compost” or “Derived from Composted Dairy Manure Solids”. No minimum guarantee shall be required in such product.
