The bag shows you an example of what each number stands for. The fertilizer here is 15.00.15 with iron.


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 10-10-10 fertilizer contains 10 percent nitrogen, 10 percent phosphate and 10 percent potash

What does fertilizer "analysis" mean?

All fertilizers have three numbers on the label which indicate the fertilizer analysis, or "percentage by weight" of nitrogen, phosphorus and potassium, in that order.

Therefore, a 50 pound bag of fertilizer labeled 20-10-5 would contain 20% nitrogen (10 pounds), 10% available phosphates (5 pounds), and 5% soluble potash (2.5 pounds).
See the calculations below:

50 pound bag of 20-10-5 fertilizer:
20% nitrogen (.20 x 50 lbs = 10 lbs)
10% available phosphates (.10 x 50 lbs = 5 lbs)
5% water soluble potash (.05 x 50 lbs = 2.5 lbs)
