If a bag of fertilizer weighs 50 pounds and is labeled 20-0-10, how many pounds of actual nitrogen does it contain?

• A. 20 pounds
• B. 10 pounds
• C. 50 pounds
• D. 0 pounds

Answer: (B)

To determine how many pounds of actual nitrogen are in a 50-pound bag of fertilizer labeled 20-0-10, you need to understand what the numbers on the label represent. In this case, the first number, 20, refers to the percentage of nitrogen present in the fertilizer. To calculate the amount of nitrogen in the bag, you take the percentage of nitrogen (20%) and apply it to the total weight of the fertilizer (50 pounds). This can be calculated with the following formula: Amount of nitrogen = (Percentage of nitrogen / 100) × Total weight of fertilizer Substituting the given numbers: Amount of nitrogen = (20 / 100) × 50 = 0.20 × 50 = 10 pounds Thus, the bag contains 10 pounds of actual nitrogen. This demonstrates how to interpret fertilizer labels to find out the nutrient content, particularly nitrogen, which is essential for plant growth.
