Calculate nitrogen rate per acre, total nitrogen needed, fertilizer product needed, nitrogen credits, application cost, and cost per acre. Use this nitrogen rate calculator for corn, wheat, forage, vegetables, and other crops.
Nitrogen rate per acre:
Enter a yield goal, nitrogen factor, and nitrogen credits to estimate pounds of nitrogen needed per acre.
Total nitrogen needed:
The calculator multiplies the adjusted nitrogen rate by field acres.
Fertilizer product needed:
Enter the fertilizer nitrogen percentage to estimate pounds and tons of product needed.
Nitrogen cost:
Enter fertilizer cost and application cost to estimate total cost and cost per acre.
A nitrogen rate calculator helps estimate fertilizer needs before application and compare crop nitrogen requirements against available credits.
It can help compare yield goals, nitrogen factors, soil credits, manure credits, fertilizer analysis, product rate, total tons, and application cost.
Your result shows estimated nitrogen rate per acre, total nitrogen needed, total nitrogen credits, adjusted nitrogen need, fertilizer product needed, tons of fertilizer product, fertilizer cost, application cost, and total cost. These are estimates based on the values you enter.
Multiply yield goal by the nitrogen factor, then subtract soil, legume, manure, and other nitrogen credits. The calculator can also adjust for application efficiency.
Nitrogen credits reduce the amount of fertilizer nitrogen needed. Common credits include residual soil nitrogen, previous legume crops, manure, compost, or irrigation water nitrogen.
Divide the pounds of nitrogen needed by the fertilizer nitrogen percentage. For example, 100 pounds of N divided by 46% nitrogen equals about 217 pounds of urea product.
Yes. Enter fertilizer cost per ton and application cost per acre to estimate fertilizer cost, application cost, total cost, and cost per acre.
