How it works
Bags = area/1,000 × target nitrogen ÷ product nitrogen fraction ÷ bag weight.
Input definitions

Common questions
Does this recommend a fertilizer rate?
No. Use a soil test, label directions and local restrictions to choose the target rate.
How does Fertilizer bags from nutrient rate calculate the result?
Bags = area/1,000 × target nitrogen ÷ product nitrogen fraction ÷ bag weight.
