If a fertilizer has an analysis of 20-0-5, what is the percentage of actual nitrogen it contains?

• A. 5%
• B. 10%
• C. 15%
• D. 20%

Answer: (D)

Fertilizer analysis is represented by three numbers that indicate the percentages of nitrogen, phosphorus, and potassium in that order. In a fertilizer analysis of 20-0-5, the first number indicates that it contains 20% nitrogen. This means that in a given amount of fertilizer, such as 100 pounds, there would be 20 pounds of actual nitrogen present. Therefore, the correct answer related to the percentage of actual nitrogen in this fertilizer is indeed 20%. Understanding this analysis helps in determining the right fertilizer for specific plant needs, especially regarding their nitrogen requirements for growth and health.
