If you aim to provide 1 pound of actual nitrogen using 20-4-10 fertilizer per acre, how much fertilizer is needed?

• A. 218 pounds
• B. 43.56 pounds
• C. 100 pounds
• D. 130 pounds

Answer: (A)

To determine how much fertilizer is needed to provide 1 pound of actual nitrogen using a fertilizer with a formulation of 20-4-10, it’s important to understand what the numbers in the fertilizer formulation mean. The first number indicates the percentage of nitrogen in the fertilizer. In this case, a 20-4-10 fertilizer contains 20% nitrogen. To find out how much fertilizer is needed to achieve 1 pound of actual nitrogen, you first calculate the amount of nitrogen provided by a specific quantity of this fertilizer. The formula to calculate the amount of fertilizer required can be expressed as: Amount of fertilizer needed = (Desired nitrogen amount) / (Percentage of nitrogen in decimal form) For the 20-4-10 fertilizer: 1. Convert the percentage of nitrogen from a percentage to a decimal: 20% = 0.20. 2. Plug the desired nitrogen amount (1 pound) into the formula: Amount of fertilizer needed = 1 pound / 0.20 = 5 pounds Since this calculation is for an area of 1 acre, and to find the total amount of fertilizer required, we need to account for the total area. To ensure we have the correct context, the answer choices suggest calculating

For the 20-4-10 fertilizer:

1. Convert the percentage of nitrogen from a percentage to a decimal: 20% = 0.20.

2. Plug the desired nitrogen amount (1 pound) into the formula:

Amount of fertilizer needed = 1 pound / 0.20 = 5 pounds

Since this calculation is for an area of 1 acre, and to find the total amount of fertilizer required, we need to account for the total area.
