Moisture content for Canadian grains

Moisture content is the measure of water content of grain. Grain that is within acceptable limits of moisture is referred to as a straight grade. With increasing moisture content, grain may be referred to as tough, damp, moist or wet. Determining the moisture content of Canadian grains is important for grain quality, safety and storage.

Moisture calibrations and conversion tables are developed from samples free of dockage.

Determining moisture content

The Canadian Grain Commission determines the moisture content of grain using a Unified Grain Moisture Algorithm (UGMA) moisture meter.

The Canadian Grain Commission monitors and maintains Canadian calibrations for model 919/3.5" or equivalent moisture meters.

If you have questions about moisture meter testing, conversion tables, or guidelines contact a Canadian Grain Commission moisture technician.

Guidelines for model 919/3.5" or equivalent
Conversion tables for model 919/3.5" or equivalent

Convert the temperature and meter reading for 919/3.5" or equivalent model meters to percentage moisture content using these moisture meter conversion tables.

These tables are reviewed annually and updated when necessary.

Tough and damp moisture ranges

Grain is identified as tough if the moisture content exceeds the straight range established for that class of grain but is not damp. Grain is identified as damp if the moisture content exceeds the tough range defined for that class of grain.
