Nitrogen $ Rate of Return Calculator
Version 4.1

     A simple (what else am I capable of!) spreadsheet can be used to evaluate different net return per acre scenarios involving N source, cost, and expected corn price.  The spreadsheet lets you look at and print multiple different combinations of fertilizer type, cost, expected corn price, and yield responses at any one time.  The user has the option of changing fertilizer type, cost, corn price, and N rate (any yellow cells).  The value with the maximum return to nitrogen is highlighted in blue.  Note:  User must select proper yield potential/soil type from the first worksheet or tabs at the bottom of the spreadsheet.

Version 4.1 approximates the April, 2010 updated UW nitrogen recommendation program for corn.  It also contains information and links to more detailed information about the recently developed regional approach to N recommendations.
