Which of the following is true when calculating the weight of fertilizer for coverage per square foot?

• A. You always use the fertilizer analysis
• B. Coverage should not exceed 1 pound
• C. Calculating should ignore the garden size
• D. The analysis is irrelevant to the calculation

Answer: (A)

The choice emphasizing the importance of using the fertilizer analysis when calculating the weight of fertilizer for coverage per square foot is correct because the analysis provides critical information about the nutrient content of the fertilizer. Fertilizer analysis is expressed as three numbers that represent the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the product. This analysis helps determine how much fertilizer is needed to achieve the desired nutrient application rate per area.

When applying fertilizer, understanding its nutrient concentration is essential for ensuring proper application rates. Without considering the analysis, a gardener may apply too much or too little fertilizer, impacting plant health and soil quality. Therefore, when planning the application, the fertilizer analysis directly influences how much product to use in relation to the specific area being treated.

The other options are flawed because ignoring garden size would result in incorrect application rates, suggesting there are limits on coverage without considering specific nutrient needs, and stating the analysis is irrelevant contradicts the fundamental practice of proper fertilizer application.
