EC MN - Hour North of 'The Cities' | So 1.25 cubic feet of ear corn weighs 72 lbs compared to 1.25 cubic feet of shelled corn weighing 56 lbs? I would think the ear corn would weigh less (cob weight is less dense than kernels, more air space in ear corn compared to shelled) in 1.25 cu ft compared to that of shelled corn.
That is what I originally thought, but I found posts on here and from NDSU saying that a bushel of ear corn is 2x the volume that of shelled corn. I thought a bushel was a bushel regardless of crop, but apparently ear corn falls in its own catagory.
If ear corn was 72 lbs in 1.25 cu ft, an example would be as follows:
Picking ear corn in a field at a yield of 300 bu/ac of ear corn (150 bu/ac shelled corn) 300 bu/ac X 72 lbs/bu = 21,600 lbs.
150 bu/ac of shelled corn X 56 lbs/bu = 8400 lbs, so 21,600 (ear corn weight) - 8400 (shelled corn weight) = 13,200 lbs of cobs in 1 acre.
Using that example, the weight of cobs per acre seems to be rather rediculous.
Using 72 lbs per 2.5 cu ft of ear corn (36 lbs per 1.25 cu ft), and the same 150 bu/ac shelled corn yield, the weight of cobs per acre comes down to 2400 lbs/ac, which seems to be a lot more realistic.
These numbers get to be confusing! |
Corn cob weight per bushel?
