Determining Reference Test Weight per Bushel Value of Grains



Gloria D. Lee


Test weight per bushel is a measurement of the weight of a volume of grain required to fill level full a Winchester bushel measure of 2,150.42 cubic inches in capacity , which is equivalent to 32 quarts. Test weight per bushel is one of the measurements used by the United States Department of Agriculture (USDA), Grain Inspection Packers and Stockyards Administration (GIPSA) in grain grading (e.g. USDA No. 1 hard red spring wheat has a minimum limit for test weight per bushel of 58.0 lb/bu) and in the market place test weight per bushel is a commercial measurement because it affects the market value of grain. When a farmer sells grain, the grain price may be discounted, e.g.; the farmer receives less money for the grain if the test weight per bushel measurement is under a certain specified target weight per bushel, such as 58.0 lb/bu. This article addresses the equipment, equipment maintenance, and procedures needed to determine the reference test weight per bushel values of grains that are used to evaluate test weight per bushel measurements in commercial transactions.
