  What are the numbers on a fertilizer label?

  Every label carries three conspicuous numbers, usually right above or below the product name. These three numbers form what is called the fertilizer’s N-P-K ratio — the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K). The product’s N-P-K numbers reflect each nutrient’s percentage by weight.

  What do the letters N and K stand for in fertilizer?

  N is used for nitrogen and P for phosphorus. The letter K is used for potassium and stands for kalium, the original Latin name for potassium. If you have trouble remembering whether P is for phosphorus or potassium, remember that the three nutrients are listed in alphabetical order.
