Harvest has started in some areas of SW Iowa on early maturity corn.  Yields have ranged from 170-200 bushels per acre so far but this is only a very small sample of the overall area.  Most full season corn is still testing 19-27% moisture so corn harvest will not be in full swing for a couple of weeks.  Most soybeans are yellowing and beginning to drop leaves so soybean harvest is also a couple of weeks out.  Very heavy rains in SW Iowa will keep farmers out of the fields for several days and we will be checking farms for storm damage and flooding early next week.
