 Topic: Soybean harvest
Posted: 19 Sep 2021 at 10:50am |

Given water weight loss at the elevator/barge, what is the highest soybean grain moisture that you’ve done without significant losses?
Obliviously Aeration in the bin afterwards to get soy to 13.0%.
Not looking for styles(air,Draper,etc..) of headers info, just what your machine could thresh adequately.
Any noteable differences per conventional vs rotor combines running wetter soybeans?? Thanks

All of our soybeans go to the elevator, so we won't start until they're pretty close to 13.0% moisture. Not sure what the combine could thresh, but I know we had a load several years ago that was north of 17%. One elevator wouldn't take them. Operator error (mine!). Cut too many from the edge of the field that were still too green. Should have blended them in with some dry ones from the middle of the field. Ooops!

Start at 15% when they are down to to 10% you are giving away yield plus you have a lot more shatter and header loss. It would be nice if a person could blend the dry with the wet, coop doesn't pay extra for dry ones  when selling food grade beans they always want them close to 13. Depends on for combining if it is early and stems are still green and beans are dry or if the plants are dry and got rain on then the pods dry again. If you can get an extra grain cart or large gravity box and put the first wet 1's on when you start the day at the end of the day you can make them disappear with the dry ones.

What page of the calendar? Early October things need to be just right later in the month less fussy, get around Thanksgiving if they shell they are great.

Back to your original question, if your machine can feed them into the cyl/rotor evenly and can knock the bean out of the pod, you can cut as many beans as you can handle to dry. We call them "butter beans". I will say in the past, when cutting beans that were replanted an acre hear or there later and you just go ahead and cut the whole field, I have had times when some of the beans would not come out of the combine grain tank. I don't know what the moisture would be but they look like lima beans. All our beans go into bins with air. You don't see the butter beans back in January when the beans get hauled out. Leon B Mo

The idea(s) mentioned by others about blending wet with dry soybeans is very credible & good results can usually be achieved without additional aeration. The 13% moisture in “dry” soybeans compute to 7.8lbs/bu water weight by volume. So if soybeans get harvested @ 8-10% moisture, then 3.0-1.8 lbs/bu is lost in water weight, respectfully. At a $12.00 commodity price per a bushel(60lbs), that extra weight loss computes to $0.60 - 0.36/bushel. If the field is yielding 75bu/acre those losses become $45-27/acre.

Last year the neighbors cows got into a 12 acre bean field and it was in a place that didn’t get noticed for a couple days. They destroyed it. It was in July and grew up in grass and weeds and what was left wouldn’t dry down. This was late and everyone else was bringing in 10% beans. It was my last field and there was a lot of rain in the forecast. I called the elevator and told them I wanted to get done. His comment was I can launder them. So I cut it with the F3 and brought him a load of 21% beans. Their insurance paid the difference.

Started harvesting soybeans this past Monday. Their Grain moisture began at 17.7 & got down to 14.5 by day’s end. Grain temp in wagon on Monday was 89 degrees.
I left the grain in gravity wagon, twisted in two perforated tube electric fan aerators into the grain, one at each end of wagon, and tarped it. Aerators pull air out of grain wagon. That night & next day we got 3+” rain. Wagon is sitting outside. Tarp is snugged up around Aerators tubes & they only run at night when air temps drops. I did run aerators during rain so water wouldn’t run in thru fans & down tubes.
Had some cool nights lately 60s-44. Today’s grain temp was 61 degrees.

This morning aeration soybean grain temp reads 53 degrees. One percent of moisture is removed per 15 degrees decrease in temp.
So 89-53 =36/15= 2.4% removed.
17.7+14.5=32.2/2=16.6% ave.
16.6-2.4=13.7%
So I’ll stop aerating it. If needed, I can use this wagon’s 13.7% to blend with any <13.0% as season progresses.
