Harvest moisture adjustment calculator

Calculate dry-matter mass and adjusted mass at target moisture with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use dry-matter mass and adjusted mass at target moisture to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Harvest mass (kg)
1000
Initial wet-basis moisture (%)
20
Target wet-basis moisture (%)
10
Dry-matter mass (kg)
800
Adjusted mass at target moisture (kg)
888.888889
Water-only mass removed (kg)

Try another scenario

Adjusted mass at target moisture (kg)

Calculation method

Calculation method

Dry-matter mass (kg)

Harvest mass × (1 − initial wet-basis moisture fraction).

Adjusted mass at target moisture (kg)

Dry matter / (1 − target wet-basis moisture fraction).

Water-only mass removed (kg)

Initial mass − adjusted mass; negative means hypothetical water addition.

Water-only shrink (%)

Water-only mass removed / initial mass × 100; zero initial mass uses zero shrink.

Symbols and units
a
Harvest mass (kg)
b
Initial wet-basis moisture (%)
c
Target wet-basis moisture (%)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Preserves dry matter and changes water only under the wet-basis convention. Actual handling losses, quality changes and buyer settlement deductions are separate. A higher target describes hypothetical water addition, not a storage or reconditioning recommendation.
