In a fertilizer labeled 16-6-8, the three numbers represent the percentage of which nutrients in order?
a.Nitrogen, potassium, phosphorus

c.Phosphorus, nitrogen, potassium
d.Potassium, phosphorus, nitrogen
Giải thích
The three-number N-P-K label always lists nitrogen first, phosphorus (as P2O5) second, and potassium (as K2O) third. So 16-6-8 is 16 percent nitrogen, 6 percent phosphorus, and 8 percent potassium by weight. Nitrogen drives leafy green growth, phosphorus supports roots and flowers, and potassium aids overall vigor.
