What do the numbers 10-6-4 represent in fertilizers?

• A. Micronutrients
• B. Nitrogen, phosphorus, and potassium
• C. pH levels
• D. Organic matter content

Answer: (B)

The numbers 10-6-4 on a fertilizer label represent the relative percentage of the three primary nutrients: nitrogen, phosphorus, and potassium, often referred to as the N-P-K ratio. In this example, the first number, 10, signifies that the fertilizer contains 10% nitrogen, which is essential for promoting leaf and stem growth. The second number, 6, indicates that there is 6% phosphorus, which supports root development and flowering. The third number, 4, shows that the fertilizer includes 4% potassium, which aids in water regulation and overall plant health. This specific ratio helps gardeners and farmers understand the nutrient composition, allowing them to select the appropriate fertilizer for their plants' needs at various growth stages.
