Most fertilizers have three numbers on their label separated by dashes. These three numbers show the percentages of nitrogen (N), phosphate (P2O5), and potash (K2O) contained in the fertilizer. A zero as the first number would mean it contains no nitrogen. A zero as the second numbers would mean it contains no phosphate. By law, all fertilizer must include a guaranteed analysis table on its label.
The first item listed in the table must be total nitrogen if there is nitrogen in the fertilizer. The second item listed in the table must be phosphate if there is phosphate in the fertilizer.
