New Calculator Tool For N, P, And K Recommendations And Fertilizer Cost Comparisons

With fertilizer being scarce and/or expensive there has never been a better time to fine-tune fertilizer use. If you want Purdue’s most current recommendations for N, P, and K and a means for comparing fertilizer costs try this spreadsheet tool: https://engineering.purdue.edu/~dbuckmas/outreach/Fertilizer_tools.xlsx
