What information does a fertilizer container label provide regarding nutrient composition?

A fertilizer container label provides a fertilizer analysis, which is essential for understanding the nutrient composition of the product. This analysis is typically represented as three numbers, indicating the percentages of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. For example, a fertilizer labeled as 10-20-10 contains 10% nitrogen, 20% phosphorus, and 10% potassium. This information is crucial for gardeners and arborists, as it helps them select the appropriate fertilizer based on the specific nutrient needs of their plants or soil conditions.

The other options do not accurately reflect the information typically provided on a fertilizer label. Soil pH is important for understanding nutrient availability but is not a direct component of a fertilizer analysis. Similarly, while some fertilizers may be marketed for specific plant types or for enhancing growth rates, these characteristics are not standard details included in the nutrient composition analysis on the label.
