Nitrogen & Phosphorus Ban in Effect
BEGINNING JUNE 1ST: In our community, the
use of nitrogen and phosphorus is banned during the rainy months when they may be inadvertently washed into drainage systems
and transported into back bays, estuaries and the Gulf of Mexico.
To assist users in understanding the amount of
each compound included in a bag of fertilizer, three key numbers are noted on every bag. These three numbers are the main
nutrients in the fertilizer — nitrogen (N), phosphorus (P) and potassium (K) — also called the NPK number. Therefore,
a fertilizer known as 10-2-20 would have 10 percent nitrogen, two percent phosphorus and 20 percent potassium.Charlotte County has enacted a fertilizer ordinance designed to regulate
two components of fertilizer: nitrogen and phosphorus. Percentages of these are indicated, respectively, by the first two
numbers in a fertilizer’s identifying code. Fertilizer use is regulated to keep nitrogen and phosphorus from
feeding algae in waterways. During the rainy months, fertilizers containing nitrogen and phosphorus cannot be used.
If fertilizer must be used, the two leading percentages must be zero: 0-0-10, 0-0- 20, or 0-0-any number.
