34-0-0 Ammonium Nitrate Calculator
Calculate 34-0-0 ammonium nitrate product per acre from a target nitrogen rate, with total pounds, bags and bulk tons for the field.
How This Calculation Works
Product pounds per acre equals the target nitrogen rate divided by the analysis percentage, times 100. For 100 pounds of nitrogen per acre from 34-0-0, that is about 294 pounds of ammonium nitrate per acre. Total product is that figure times acres.

Common Questions
How much 34-0-0 do I need for 100 pounds of nitrogen per acre?
Divide 100 by 0.34 to get about 294 pounds of ammonium nitrate per acre. The 34 percent analysis means each pound of product carries 0.34 pound of nitrogen. Multiply by acres for the field total.
Why is ammonium nitrate popular for sidedressing?
Half its nitrogen is nitrate, which is immediately available, and half is ammonium, which resists volatilization until it converts. That balance makes it reliable for in-season nitrogen without incorporation. It also dissolves readily for liquid applications.
Is ammonium nitrate dangerous to store?
It is a strong oxidizer and can accelerate combustion, so it must be stored away from fuels, oil and organic material. Many jurisdictions regulate its sale and storage. Follow local security and fire-code requirements.
Can I blend ammonium nitrate with urea?
Blending the two in bulk is discouraged because the mixture becomes hygroscopic and can turn sticky or hard. Apply them separately or use a commercial blend designed for compatibility. Check compatibility charts before ordering a custom mix.
