What is the weight of fertilizer needed if applying 2 pounds of actual nitrogen for 2,000 square feet using 16-4-8?

• A. 25 pounds
• B. 50 pounds
• C. 30 pounds
• D. 20 pounds

Answer: (A)

To determine the amount of fertilizer needed to apply 2 pounds of actual nitrogen to a 2,000 square foot area using a fertilizer with a ratio of 16-4-8, it's important to understand how to calculate the actual nitrogen content in the fertilizer. The first step is to recognize what the numbers in the fertilizer analysis mean. The first number (16) represents the percentage of nitrogen in the fertilizer. Therefore, in every 100 pounds of this fertilizer, there are 16 pounds of actual nitrogen. Next, if we want to apply 2 pounds of actual nitrogen, we can set up a proportion to find out how many pounds of the 16-4-8 fertilizer we need to use. If 16 pounds of nitrogen comes from 100 pounds of fertilizer, then 2 pounds of nitrogen would be derived from: (2 pounds of nitrogen) / (16 pounds of nitrogen per 100 pounds of fertilizer) = (X pounds of fertilizer) / (100 pounds of fertilizer) Cross-multiplying to solve for X gives us: 2 * 100 = 16 * X 200 = 16X X = 200 / 16 X = 12.5 pounds However, we've found the amount

(2 pounds of nitrogen) / (16 pounds of nitrogen per 100 pounds of fertilizer) = (X pounds of fertilizer) / (100 pounds of fertilizer)

Cross-multiplying to solve for X gives us:

2 * 100 = 16 * X

200 = 16X

X = 200 / 16

X = 12.5 pounds

However, we've found the amount
