The Fertility Recommendation Spreadsheet has been updated to provide more functionality in developing fertility recommendations based on the tri-state fertilizer recommendation. Feedback from the release last fall was used in updating this version.
New functions include:
· Phosphorus soil test results from either either Bray P1 or Mehlich III can be entered directly without conversion.
· Phosphorus and Potassium soil test reported in units of pounds per acre or part per million can be used.
· A lime recommendation sheet provides lime need adjusted based on ENP of liming source and calculates cost for product and application.
· A fertilizer recommendation sheet calculates dry fertilizer need and cost on the per acre and total field basis.
· Crops included include corn, soybeans, wheat (grain only), wheat (grain and straw), corn silage and alfalfa.
