What is the weight per bushel for ear corn??? I found on the net that it is 70lbs, so that means that our 190bu wagon should hold 6.65 tons. We sold better than half a wagon load to a guy and he said that it didn't quite look like 2 ton, but we measured his truck bed and it came out to over 3 ton using 70lbs/bu. This our first year selling corn, and I don't want to rip anyone off, but I don't want to get taken either.

How about a simple answer-35 to 45 lbs. under most conditions. Straight out of the field it may be a little more, after six months in a crib it may be a little less. We always figured about 70 bushels of ear corn equaled a ton of shelled corn. It varies with moisture, variety, and growing conditions.

How many pounds in a bushel of corn? How many bushels are in a ton?

I don't know how accurate it is, but you can put a pressure gauge in the lift circuit of the loader. It should always be used at the same height, bucket in the same position, and try to have the load about the same position in the bucket. The reading can also be affected by whether the load was being raised or being lowered into the reading position. It would take time and effort to calibrate the thing, but it sure beats just guessing.

I am a feld reporter for the USDA in Western WI.
Here is how we are required to measure all grain for certification.
We take a sample of the grain . Take the temp and it us used to determine the % of moisture. Corn that is 15% and less make no adjustment.
On cob corn we shell it and then take a weight. In Western WI last year the Corn was running about 56 lb average.
We use a chart after measuring the container that the grain is in. The total volume X 0.8 for almost all grain, Ear corn vol. X 0.4 and settled ear corn vol X0.444 will give you the total bushels
We also facture in the width of the bin, and if it is over a set SQ FT the total CU FT is ajuster up because if packing .
I hope that my answer is not too long but just wanted to let you know how it is done for sealed bins

it's been a while but when i bought or sold it ,we figured 72 pounds a bushel for 'wet' and 68 # for 'dry' .i used to weigh single ears of corn and if i remember right a 3/4 # ear of corn would give me a half pound of shelled corn.

STEVE, if you fill a basket with ear corn it will weigh about 45 pounds

Steve: First let me say your question is just a bit too brief to give a good answer. When you say ear corn, are you talking whole cob as picked, combined with combine set in such a way it breaks the cobs or ground ear corn. Each one will weigh different per bushel. By the way a bushel is 1.28 cubic feet. Even selling ear corn buy weight can be decieving unless you factor in moisture content and sell on a dry corn basis, being 15.5% moisture.

I think we all agree that dry shelled corn (15.5%) will run 56 lbs per bushel. Whole cobs in a wagon are going to weigh less per bushel, just on the air space alone. Combined ear corn will also run lighter than the 56 lbs per bushel, simply because the cob material is lighter than the grain. I think I am quite certain you are not looking at ground ear corn, however having some experience selling it that way. I can say it will come back close to 56 lbs per bushel.

Remember one item though, unless you guys factor this on a dry matter basis you are only at best, guessing.

First off, thanks for all the replies. With that said, is that how ear corn is sold, based on the amount of shelled corn it will yeild and not counting the weight of the cob??? If I fill a bushel basket of ear corn and weigh it, it will weigh 70lbs, but only yeild 56lbs of shelled corn. And that is how I should calculate it based on 56lbs/bu or about 35 bu/ton?? I want to measure our loader bucket and find out how many bu it holds and how may scoops makes a ton. Just want to be sure. Thanks.

two ways to sell ear corn by the ton=get it weighed on a scale by the shelled bushel equivalent= cubic feet times .4

No.

They are assuming 56lbs of shell corn in a bushel, PLUS the 14lbs of corn cobs. Filling a bushel basket with ear corn will not give you a bushel of corn. It is not figured that way.

There really is no 'bushel' of ear corn - it is always figured on a bushel of shelled corn, PLUS the cobs.

Amount of settling makes a real big difference - what you have in the pile will be much more compacted than what you have in the bucket.

The only way everyone is happy is to find a scale within ~15 miles & weigh. Maybe establish a pattern from a couple of loads, and then both of you will be happy with assuming the same weight for the same volume in the wagon/truck.

Ear corn is extremely variable due to packing/settling, cob size, moisture content, and ear fill. Guessing by volume is a poor way to go.

Even on shell corn, I was getting 387 bu per 2 wagons full on my poorer, 22%, 51# test weight shell corn, while at the end, my 14%, 58# corn hit 430bu per the same 2 wagons, same fill - to the top.

That is a pretty big variation - over 10%, and ear corn is far bigger. One of you is going to get short-changed by counting scoops....

Paul is correct. If you are selling on a true bushel, the weight of corn being sold will vary greatly.

Industry standard is a 56# unit of corn. That is commonly called a bushel. That is what is traded commercially. Just a "unit" of corn, not a true bushel.

This year in south central MN, I would have poorer yields going by a "true" bushel. One 40 acre field had an average test weight of 61#. The field did 174.4 of an average of 13.6% moisture corn straight from the field. True yield "bushel" wise was only 160.

Best thing to do is sit down with the buyer using the advise as a guideline and come to an agreement that is satisfactory to both of you. Then it doesn't make any difference as to what weight, moisture, etc corn you have.

A Bushel of #1 corn, 1.25 cubis feet, is 56 lbs. It takes two bushels of ear corn, weighing 72 pounds, or 36 pounds per bushel, to yield a bushel of shelled corn; thus about 16 pounds of cobs and the moisture within them.

Calculate the volume of your wagon in cubic feet then times .8 for bushels, times pounds per bushel

In a old John Deere book they say a busel of ear corn measures 2.5 cubic feet. This is corn settled in a crib and husked clean so the cubic feet may be slightly more in a truck box. I hope this may help.

This gets confusing. 70 lbs of ear corn will yield 56 lbs. (or a true bushel by volume) of shelled corn. 70 lbs of ear corn will occupy more than a bushel volume-wise. So your 190 bu. wagon is actually holding around 150 bu. of ear corn. I always sell ear corn by the pound or ton. No cheating on either side that way.

Thats my problem. We want to sell by the ton, but we have no scales to weigh the truck. I need to know how much volume a ton fills. I figured a bushel is about 1.25 cubic feet, and 70lbs/bu..... .I guess I will have to poke around and see what the other guys around here do.

Really need to find scales. If nothing else fill a wagon and take it where to a scale and then sell that size wagon at that weight. I used to weigh at the concrete company but it is a 30 mile round trip. Had a 'duh' moment and realized that the distillery 2 miles from me had scales. Started using theirs. They dont charge me to do it, even. See if you can find a DOT man who lives in the area, offer to pay him to come out when he is off work and use his portable scale.

70 #s is the approximate earcorn weight equivalent to a bushel of shelled corn. 1.25 cu ft would be the normal volume for a bushel of grain. A bushel of ear corn by volume would have a lighter weight than shelled corn. Besides moisture the issues the weight will vary if it has been husked or by how much of the husk remains if not completely husked by the picker. The key is that you and the purchaser are on the same page. The use of a loader bucket may not provide a very uniform measure because of the settling issues. Anyone that has unloaded wagons by hand with a scoop can tell you about the difference in how hard it is packed between a load picked close the crib and one that has bounced around over a couple miles of backroads.

surely there is a scale somewhere near you. Check around ask some truckers were they weigh. I have weighed at concrete company, feed mill, fertilizer plant, feedlot, yes even a truckstop. It is not uncommon here for farmers to drive 10-20 miles out of their way to weigh.

Grain coop charges a buck to weigh on their scale here - let it go free if it's a reg customer & not often. See a lot of livestock trailers go over their 'crop' scales.

Should be something around. Very, very hard to figure volume on shell corn. I have to for the LDP plan at FSA - I always get 5-7% more corn out of it than they figure by volume. Sometimes much more. Cob size & kernal fill vary so very much.
