Bushel of soybeans vs bushel of corn
Here is the scenario. Take a dump trailer of a constant volume, fill it full of corn and take it to the elevator and it's 800 bushels. Now take the same trailer and fill it to the same (close) point with soybeans and take it to the same elevator. Now its 700 bushels at the same moisture. I know corn and beans have a different density (lb/bu) but if bushels are a volume what gives? Is there a bushel for weight?

This fact sheet might help explain: http://ohioline.osu.edu/agf-fact/0503.html A couple of things to consider is that the standard moisture for corn and soybean differ. Corn is 15% whereas Beans are 13.5%. So, if sold at the same moisture, the beans will be larger than the bushel of corn. If higher moisture, the elevator would doc you the difference, if lower they may not give you a premium. The other item to consider is test weight #/bu, If one of the two grains had a higher test weight, you can fit more weight in the space compared to the standard, since the elevator uses your weight in a standard formula, differing test weights could result in small changes in the number of bushels. Again, low test weights may get docked but higher weights may not get any additional benefit, other than the higher weight for the same volume. The fact sheet above should help. If you have your test weights and moistures, I can help you work through the calculations further. Great question!
