GRAIN GRADING

1

• GRAIN GRADING

LANGUAGE OF QUALITY
2

• GRADING IS THE PROCESS OF DIVIDING A COMMODITY
  INTO CLASSES, EACH OF WHICH HAS A DISTINCTIVE
  ACCEPTABILITY TO A SIGNIFICANT GROUP OF BUYERS.

3

• CRITERIA FOR GRADES AND STANDARDS

• BUILT ON CHARACTERISTICS THE USERS CONSIDER
  IMPORTANT
• BUILT ON THOSE FACTORS THAT CAN BE ACCURATELY AND
  UNIFORMLY MEASURED AND INTERPRETED
• COST OF OPERATING THE SYSTEM MUST BE REASONABLE

4

• CONTRIBUTIONS TO OPERATIONAL EFFICIENCY

• TIME SAVER FOR TRADERS
• BUY AND SELL OF UNSEEN COMMODITIES
• TIME SAVER FOR CONSUMERS
• NO NEED TO INSPECT EACH LOAD
• TIME SAVER FOR LENDERS
• NO NEED TO INSPECT COLLATERAL
• PERMITS MIXING OF SEPARATELY OWNED COMMODITIES IN
  STORAGE OR TRANSPORTATION

5

• PRICING EFFICIENCY
• ALLOWS FOR COMMUNICATION

6

• GRADING GRAIN CHARACTERISTICS
• TEST WEIGHT
• BROKEN CORN FOREIGN MATERIAL
• DAMAGED KERNELS

7

• TEST WEIGHT IS A MEASURE OF GRAIN DENSITY AND IS
  DETERMINED BY WEIGHING THE QUANTITY OF GRAIN
  REQUIRED TO FILL A WINCHESTER BUSHEL (VOLUME
  MEASUREMENT)

8

• BROKEN CORN AND FOREIGN MATERIAL
• PIECES OF KERNELS OF CORN AND ALL MATTER OTHER
  THAN CORN THAT WILL PASS THROUGH A 12/64 -INCH
  SIEVE

9

• TOTAL DAMAGED KERNELS
• IS DEFINED AS KERNELS AND PIECES OF KERNELS THAT
  ARE HEAT DAMAGED, SPROUTED, FROSTED, WEATHER
  DAMAGED, MOLDY OR DISEASED

10

• WHAT OTHER QUALITY CHARACTERISTIC MIGHT BE
  CONSIDERED?

11

• EVALUATING THE ADEQUACY OF GRAIN STANDARDS

12

• 1. BCFM CLASSIFYING PIECES OF GRAIN, DIRT WEED
  SEEDS AS HAVING THE SAME VALUE.

13

• 2. LOWEST FACTOR APPROACH PLACES GRAIN IN THE
  SAME GRADE THAT COULD LIKELY HAVE WIDE DIFFERENCE
  IN OVERALL QUALITY.

14

• 3 THE PRESENT SET OF GRADES EXCLUDES FACTORS
  THAT ARE ECONOMICALLY IMPORTANT.
