SAMPLING AND COLLECTION METHODS FOR U.S. WHEAT
Data shown in the USW Crop Quality Report is based on composite sample averages. The overall average values are weighted by export tributary. Individual samples are used to create the distributions shown in the USW Crop Quality Report.
SAMPLE SIZE
300gto 6,800g
515AVERAGE NUMBER OF SAMPLES
Sampling and Collection Methods for
Hard Red Winter Wheat
100Average number of composites, which are based on pro-
tein and grainshed.
SAMPLING AND COLLECTION
Collection occurs when harvest is 30% complete in the grainshed. Follow-up sampling is done if a major weather event occurs that impacts quality.
Collection begins the third week of July.

Data shown in the USW Crop Quality Report is based on composite sample averages. The overall average values are weighted by the number of samples received from each region. Sampling in the PNW is generally correlated to regional production. Individual samples are used to create the distributions shown in the USW Crop Quality Report.
