Crop Calculators has three corn crop calculators:

Silage Moisture Cost Adjuster for Corn

  • This calculator compares a negotiated price for silage and adjusts the price, taking into account how much moisture is present.
  • Simply enter the negotiated moisture and price, along with the actual moisture content, and the adjusted price will be calculated.
  • Calculations are cleared when you close the app. To create and share a report of your calculation, use the “Email report” button provided.

Maturity Date Predictor for Corn

  • When you enter a tassel date, date ranges for 50% kernel milk and black layer will be calculated.
  • If you then enter a frost date, these date ranges will change color to indicate whether the frost will occur before or after the date range.
  • Green indicates that the predicted frost occurs after the beginning of the range and you’re in the clear. Red indicates that the frost occurs before the range.
  • Calculations are cleared when you close the app. To create and share a report of your calculation, use the “Email report” button provided.

Grain Yield Estimator for Corn

  • First, enter the density of your field in plants per 1000th acre.
  • The next three inputs are suggested values, but should be adjusted throughout the growing season.
  • Calculations are cleared when you close the app. To create and share a report of your calculation, use the “Email report” button provided.
