AMS-GD-2020-31 - Mixed Grain

  1. Can the percentage of FM and fines and the percentage of each kind of grain exceed 100 percent?

    Yes, because the basis of determination requires that the percentage of grains comprising the mixture be made on a representative portion after the removal of FM and fines. Record the percentage of FM and fines and each kind of grain to the nearest whole percent.
  2. Is it permissible to analyze protein for Mixed Grain when wheat is the predominant grain in the official system?

    No. Protein is not allowed under the official system for Mixed Grain no matter what grain predominates.
  3. The grade chart for Mixed Grain does not list moisture as a sample grade factor when the moisture exceeds 16.0 percent. Is this correct?

    No. This was an oversight and will be corrected in the next printing for Mixed Grain. Under Section 6.10, Moisture, Certification, Mixed grain containing more than 16.0% moisture is graded U.S. Sample Grade.
