What is the composition of a fertilizer that is labeled 23 - 6 - 4?

A fertilizer labeled 23-6-4 indicates its composition in terms of weight percentage for three key nutrients: nitrogen, phosphorus, and potassium (often referred to as potash). In this case, the first number represents the percentage of nitrogen, the second number represents the percentage of phosphorus (expressed as phosphate), and the third number represents the percentage of potassium (expressed as potash).

Thus, in the case of a fertilizer labeled 23-6-4, it contains 23% nitrogen, 6% phosphorus, and 4% potassium. This specific composition is important for understanding the nutrient balance required for optimal plant growth and development, allowing landscapers and gardeners to choose fertilizers based on the specific needs of their plants and soil conditions.

Other options provide different percentages that do not align with the 23-6-4 label, which is crucial for providing the right nutrients to support healthy plant life.
