Explanation:

The three numbers on fertilizer represents the value of three macro-nutrients used by plants which are nitrogen, phosphorous and potassium (NPK). Higher the number represents the more concentrated nutrient in a fertilizer. NPK rating is written as three numbers separated with dashes (9-2-2). A 40-pound bag of fertilizer is labeled as 8-2-2 contains (8% of 40 Nitrogen), (2% of 40 Phosphorous) and (2% of 40 Potassium).
