| I stand corrected. I looked for awhile and finally came up with some info from K-State about wheat test weight.
"In some cases, the test weights at maturity were fine this year, but rains at harvest time lowered the test weights by 2-3 points or more almost overnight. In this case, the reason for the low test weight is that the rain causes the wheat kernels to swell – something like puffed wheat cereal. Test weight is a measure of how much grain weight can be placed in a given volume. Prior to the rain, the wheat kernels could be packed well into a bushel. When it rains, kernels swell and upon drying, the kernels do not shrink back to their original volume, shape, and smoothness. This results in more space between kernels, and they will not pack into a bushel as well as they did before the rain. The result is a lower test weight. But this does not reduce the total number of pounds of grain produced per acre. There is no real grain yield loss – the number of bushels per acre will be increased but the weight per bushel will be reduced."
Won't be the last time I am wrong.
