Drop a pin to your field and fill in some necessary information (e.g., soil type, tillage, and other management). Yield and profit for the fertilizer formula (N-P-K-S-Zn) you want to test, will be estimated for rates between 0 to 300 lb/ac of actual N.

This tool performs economic analysis.

Make sure you have the following before you start:

1) Fertilizer cost ($ per ton of product)

2) Projected corn price ($/bu).
