Calculating % Slow Release Nitrogen
A product with 50% slow release nitrogen means that half of the nitrogen is
available immediately and half will be slowly released over a period of time.
Some nitrogen sources are “quick release” and other sources are “slow release”.
Other names are interchangeably used, such as timed-released,
controlled-release, slowly-available, or water-insoluble.
Fertilizer Labeling
GUARANTE
A Complete Fertilizer Contains Nitrogen (N), Phosphorous (P) and Potassium (K).
Understanding the label:
Example: a 40-lb. container of fertilizer
is comprised of:
Nitrogen (N) 6.4 lbs.
Phosphorous (P) 0 lbs.
Potassium (K) (Potash) 3.2 lbs.
16 - 0 - 8
Fertilizer
The remaining 30.4 lbs. are made up of
other nutrients, conditioners and fillers.
*All granular
or solid fertilizer
sold in Pinellas County
must be at least 50%
or half, slow-release
nitrogen.
