About this app

This app is designed to assist producers in selecting a nitrogen (N) rate that improves profitability when nitrogen and corn prices fluctuate. Maximum return to N (MRTN) is the N rate that will be most profitable for a particular N:Corn price ratio. The MRTN rate is the large number expressed in lbs N/acre at the bottom of the screen, and is the total N rate recommended for your field. From this number, you need to subtract the lbs N/acre starter you apply and subtract the lbs N/acre N credits you take. Below the single large number is the range of N rates that result in profitability within $1/acre of the MRTN rate.

This app apparently doesn't compensate for different areas of the country, because it recommended 125 units for corn on corn, which is at least 60-80 units below what we need here.

We will make it more clear that this app is made using University of Wisconsin rate guidelines. It is true that N rates tend to be state specific. Thanks for the comment.
