8 million more acres of corn in Iowa for 2008? We can shift some soybean acres to corn, but not a great amount. Some will come out of CRP, but I can't see enough A) yield) and B) acres coming from there to make a big dent.
As I have a seed production background, I started thinking about the need for seed corn in 2008. At 2.75 acres per unit (about 50 lbs, or 80,000 kernels) of seed corn, about 2.9 million units of extra seed corn would need to be produced?
Ever heard of Garst, Asgrow, Mycogen, or Golden Harvest seed companies? Take any two of them, add them together, and you have about 2.9 million unit production per year.
Pioneer has lost a lot of market share in the last few years to companies such as listed above. So, they have extra capacity to make up the extra demand...that is if you wanted to plant Pioneer.
Anyway, probably not all of the ethanol plants will be built, so the demand for corn may not be as high as Wisner predicts. However, the demand will still be higher than in the past, and we may not shift as many corn acres as needed. Iowa becomes a net IMPORTER of corn? Could happen...
