Frequently asked questions
- How do I calculate fertilizer application rate?
- Determine the nitrogen you need (area ÷ 1,000 × N rate). Then divide by the fertilizer's N percentage (first NPK number ÷ 100). Example: 5 lbs N ÷ 0.10 = 50 lbs of 10-0-0 fertilizer.
- What does NPK mean on fertilizer?
- NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K) — the three primary nutrients. A 10-10-10 fertilizer contains 10% of each by weight.
