PART D - COMMERCIAL GRAIN GRADING

  1. The commercial grading of grains will be based upon the standards of the Consumer and Marketing Service, Grain Division of the U.S. Department of Agriculture, as set forth in the Official Grain Standards of the United States Handbook - The latest handbook available on January 1 each year at (http://www.usda.gov/gipsa) will be used. A limited number (5) of handbooks may be obtained at no cost from Frank W. Kretzinger, 465 Custom House, Denver, Colorado 80202, or by telephone 303-297-4576. Copies are available from the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402. Handbooks will be provided at the contest.
  2. The grading will consist of:
    Class
    1. WHEAT
      Hard Red Winter
      Hard Red Spring
           Subclasses: Red Spring Wheat, Dark Northern Spring, Northern Spring Wheat
    2. CORN
      White
      Yellow
      Mixed
    3. OATS
      White
    4. RYE
    5. MALT BARLEY
      Two-rowed

    Two problems, winter hard red winter and/or hard red spring wheat; oats; rye, malt barley and corn will be used to make up the grading phase of the contest.
    No actual grain samples will be worked. Master sheets listing grading factors will be furnished to each contestant.

  3. Only the following special grades may be used in the contest:
    WHEAT
    smutty
    light smutty
    garlicky
    treated
    ergot
    OATS
    heavy
    extra heavy
    thin
    smutty
    garlicky
    ergot
    bleached
    bright
    RYE
    ergoty
    light smutty*
    plump
    smutty
    light garlicky
    weevily
    CORN
    flint flint and dent waxy*
    MALT BARLEY
     
  4. Grading will be done on two problems from card factors only. Approximately five minutes will be allowed for each problem.
  5. The contestant must indicate with an "X" in the proper circle on the score sheet the correct grade, subclass, class and factors which apply for each problem. In addition, information will be furnished on the card whereby the contestant will be expected to determine percent dockage and special grade where applicable.
  6. Grading factors: A reason why a grain goes down in grade. A grain which grades No. 1 has no grading factors and need be given none. A grain grading No. 2 or lower must have a factor or factors which bring it down. Only the factors which bring it down to the lowest grade should be marked.

    Examples:

    Problem No. 1 - Hard Red Winter Wheat
    Card Information:
    Test weight 56#, odor-natural, sprout damage 4.5% vitreous kernels 70%, dockage 1.3%
    Answer:
    The contestant will indicate by marking an "X" in the appropriate circle. Grade U.S. No. 3, Hard Winter Wheat, Dockage 1%; Grading factors, total damage 4.5%, test weight 56#.

    Problem No. 2 - Hard Red Spring Wheat
    Card Information:
    Test weight 60#, foreign material 4%, odor-natural, 80% dark, hard vitreous kernels.
    Answer:

    Card Information:
    0.2% frost damaged kernels.
    0.1% mold damaged kernels.
    1.0% wild oats.
    6.0% skinned and broken.
    10.0% passed through a 5.5/64 x 3/4 sieve.
    2.0% foreign material.
    Answer:
    Grade U.S. No. 3; Grading factors, foreign material, thin barley.
