When calculating the amount of fertilizer needed for a 2,000 sq. ft. area using a 13-13-13 fertilizer, how much fertilizer is required for 2 lbs. of actual N?

When calculating the amount of fertilizer needed for a 2,000 sq. ft. area using a 13-13-13 fertilizer, how much fertilizer is required for 2 lbs. of actual N?

• A. 15.4 lbs.
• B. 30.8 lbs.
• C. 40 lbs.
• D. 25 lbs.

Answer: (B)

To determine how much fertilizer is required to provide 2 lbs. of actual nitrogen (N) using a 13-13-13 fertilizer, you can follow the steps below. A 13-13-13 fertilizer contains 13% nitrogen by weight. This means that for every 100 lbs. of fertilizer, there are 13 lbs. of actual nitrogen. To find out how much total fertilizer is needed to obtain 2 lbs. of nitrogen, you can set up a proportion based on the percentage of N in the fertilizer. First, if 13% of the fertilizer is nitrogen, then to calculate how much fertilizer is needed for 2 lbs. of nitrogen, you can use the formula: Amount of fertilizer = (Desired nitrogen amount) / (Percentage of nitrogen) In this scenario, you are looking for: Amount of fertilizer = 2 lbs. / (0.13) Calculating this gives: Amount of fertilizer = 2 / 0.13 = approximately 15.38 lbs. However, the closest correct answer to the total fertilizer needed for 2000 sq. ft., when adjusted for the entire application, would involve multiplying this value by a factor that accounts for the area. Since 15.38

In this scenario, you are looking for:

Amount of fertilizer = 2 lbs. / (0.13)

Calculating this gives:

Amount of fertilizer = 2 / 0.13 = approximately 15.38 lbs.

However, the closest correct answer to the total fertilizer needed for 2000 sq. ft., when adjusted for the entire application, would involve multiplying this value by a factor that accounts for the area.
