In the N-P-K fertilizer formula, which nutrient does the middle number represent?

Explanation:
On fertilizer labels, the trio of numbers shows how much of three nutrients are in the blend, in this order: nitrogen, phosphorus, and potassium. The middle number, therefore, represents phosphorus. Phosphorus supports root development and energy transfer within the plant, which is crucial for strong establishment and flowering/fruiting. Nitrogen drives leafy growth and greenness, shown by the first number, while potassium influences overall vigor and stress tolerance, shown by the last number. Calcium is not part of the N-P-K trio, so it isn’t represented by these three numbers.
