Corn depth of kernal can benefit from rain (filling the kernal) until it dents. Late April and May planted corn would be in that category. Soybeans have been in a holding pattern or dormant defensive mode and will respond 100%, although not able to reach the potential it had at one time. Generally speaking, Corn East of I-35 to the Eastern edge of the corn belt (border of Ohio/PA.) is done. That area was planted earlier this year.
Speaking of flooding, the Mississippi at a crucial point, is 10' deep in the channel. Larger barges have been parked and even smaller barges have to wait for periodic dredging to allow for traffic flow. Of course not as much grain will be traveling to NO via the Mississippi this year but still, its not often this situation rears its ugly head.
IMO, the 3 dry years we experienced in the mid to early 80's were far worse for grain production. At that time we did not have RUP hence no-till was unavailable and bio-tech seed was not on the market. We dryed the top foot of soil out with tillage, had weed pressure and corn was not bred to withstand stress. And MPCI crop insurance sucked. On top of that the financial "farm crisis" was at full roar which impacted land values which destroyed equity. This drouth is not good but if we were using the practises and seed from the 80's, it would have been all over a month ago.
As far as marketing, we are cleaning out bins as I speak. Give or take $8 is good enough for me. The end user can not sustain profitable margins much beyond that figure. Ethanol plants are reducing output now and only operating because they have some bushels being delivered on old contracts. When those run out, I suspect that they will not operate at a negative margin and just produce enough to keep the plant and employees operational.
It will be a long interesting survival mode for the livestock and ethanol producer until the 2013 crop becomes available.
