Southern MN | Our findings have always been there is more phantom yield loss in soybeans than corn. If you can get green stemmed soybeans at 13% the first time they dry down you will have more deliverable yield. Am always amazed how nobody ever talks about it. Am guessing this is more of a northern belt earlier maturity phenomena. We are seeing about 6 percent less yield than the beans taken 1-2 weeks ago. They later beens (2.1s) should have a 5-10% yield advantage (or more) over the early beans(1.4-1.6’s). Yesterday field averages around 10 percent so that explains a 4% or so loss based moisture loss. When you roughly add all that together and add the moisture back in to the 10 percent beans we are roughly 8% - 9% short of where we should be. Not very scientific and written from the combine seat but this is usually what we see most years. Soybeans harvested today will be worse. Happens most years but this year is more e cause the wind and heat came on the first or second day of soybean harvest for most. Don’t have to agree but in our area it is real.
BTW measurable harvest losses were not bad at all yesterday, I do believe when it gets drier some kernels/seeds get pulverized and we don’t account for them when checking for harvest loss. Also had later August rains here to help later maturing beans. | |
