The bag shows you an example of what each number stands for. The fertilizer here is 05.10.15

This has been a great starter fertilizer for watermelons, cantelopes, tomatoes, cucumbers, peppers etc for many years.

All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) - phosphorus(P) - potassium(K)).

This label, known as the fertilizer grade, is a national standard.

A bag of 05-10-15 fertilizer contains 05 percent nitrogen, 10 percent phosphate and 15 percent potash
