Which fertilizer ratio among the given options has the highest nitrogen percentage?

• A. 5-10-5
• B. 0-10-15
• C. 12-6-4
• D. 5-15-5

Answer: (C)

Nitrogen content is shown by the first number in an N-P-K fertilizer ratio. That first number tells how much nitrogen is in the mix. Among the options, the first numbers are 5, 0, 12, and 5. The highest is 12, so the ratio 12-6-4 contains the most nitrogen. Higher nitrogen promotes leafy growth and a rich green color, but it may not supply enough phosphorus and potassium for flowering, root development, or overall balance, so choose based on what the plants need.
