Corn Moisture Correction

The Corn Moisture Correction formula computes the correction factor for corn weight based on the corns measured moisture percent.

INSTRUCTIONS: To compute the moisture correction factor for corn, enter the following:

• (w)  This is the percent (%) of moisture in your corn

Moisture Correction Factor: The calculator returns the Moisture Correction factor.  This function is part of the Corn Yield Estimation Calculator.

The Math / Science

A Moisture Correction Factor is used as a factor in corn yield estimation in order to compensate for the change in moisture in the corn from the field to the dried corn sold at market.  The assumption is that corn is harvested and dried to the industry standard level before it is sold on the market.  Therefore, this formula uses the moisture of dry corn (MDC = 15.5 %).  It approximates the amount of shrinkage by volume that will occur from the field to the point it's ready for the market due to drying.

Moisture Measurement Methods

This simplest method to measure the percentage of moisture is with specialized equipment for the purpose such as Digital Moisture Balance or other moisture tester.  There is also a method using equal size samples, a good scale and your microwave oven.  (See HERE)

The US Corn Price Survey table is an informal survey of the market value of No. 2 Shelled Corn.

The US Corn Price Survey information is as follows:

• Date: 7/17/24
• State: PA
• Region: New Holland`
• Corn Price (low): $4.08 USD/bu
• Corn Price (high): $4.48 USD/bu

The US Corn Pricing Survey is for No.2 Shelled Corn

The Corn Pricing Data can be used for the Corn Crop Value calculator, CLICK HERE.

Corn Calculators:

• Corn Yield Estimation Calculator - Estimate the size of corn harvest (number of bushels) while the crop is still in the field based on a sample, acres planted and quality factors (kernel size and moisture).
• Crop Value Estimation - Estimate the value of a crop based on the acres planted, yield per acre and dollar per bushel.
• Corn Products - Estimates the amount of derivative products that can be produced based on a volume (number of bushels) of corn including: pounds of beef, pork and poultry, corn oil and ethanol.
• US Corn Pricing Survey - Regular survey of market prices of corn

Market Ready Grain Weights per Bushel

• Weight of Corn - 56 lb/bu
• Weight of Wheat - 60 lb/bu
• Weight of Barley = 48 lb/bu
• Weight of Oats - 32 lb/bu
• Weight of Rye - 56 lb/bu
• Weight of Soybean - 60 lb/bu

Grain Crop Calculators:

• Grain Crop Weight Estimation - Estimate the weight of a grain harvest based on the number of bushels and pounds per bushel of the grain.
• Grain Crop Value Estimation - Estimate the value of a grain crop based on the acres planted, yield per acre and dollar per bushel.
• US Corn Pricing Survey - Regular survey of market prices of corn
• US Wheat Price Survey - Regular survey of market prices of wheat
• US Soybean Price Survey - Regular survey of market prices of soybean
• Quantity Required for Moisture Blending - Computes the amount of grain needed of one moisture level to mix with another to achieve a desired moisture level.
