The three numbers on the front of a bag of fertilizer refer to the percent (guaranteed minimum) of the three major nutrient elements in that particular fertilizer. In our example the actual amounts of these elements could be 25% Nitrogen, 17% Phosphorus, and 11% Potassium. Keep in mind that the numbers on the bag are the lowest amount of each element you will find in the bag.
A label that reads 20-15-10 should be translated as:
20% Nitrogen (N)
15% Phosphorus Oxide (P2O5)
(known as Potash)
10% Potassium Oxide (K2O)
