Learn how to read and use fertilizer label information
The following is a description of information found on fertilizer
packages. Use fertilizers specifically blended for your particular types of
lawn or landscape plants. The package will identify the type of plants
for which the fertilizer is blended.
The Guaranteed Analysis label
Each fertilizer package must have a label that provides the consumer
specific information about the product. Figure 1 shows the generic
information on a Guaranteed Analysis label and Figure 2 is an actual
label (with the name and license number changed). This label is usually
located on the back or side of the package. The Guaranteed Analysis
label tells you, in order, the percent by weight of Nitrogen (N),
Phosphorus (P) and Potassium (K).
Figure 1
For example, as shown in Figure 2,
a 29-3-4 fertilizer means that 29% of
the product is nitrogen, 3% of the
product is phosphorus (phosphate)
and 4% of the product is potassium,
the primary nutrients respectfully
found in the product.
