In a fertilizer 10-6-4, what percent nitrogen does it contain?

• A. 10%
• B. 6%
• C. 4%
• D. 2%

Answer: (A)

The numbers on a fertilizer label show how much of the major nutrients are present by weight, in the order nitrogen, phosphorus, and potassium (N-P-K). So in a 10-6-4 mix, the first number is nitrogen, meaning the fertilizer contains 10% nitrogen by weight. That’s 10 grams of nitrogen per 100 grams of fertilizer. The remaining numbers indicate phosphorus (6%) and potassium (4%).
