8-14-12 (St. Paul, MN) --  Minnesota farmers have just about completed their small grains harvest this year--quite a bit ahead of the average pace.  The weekly crop update from the Minnesota Department of Agricultural Statistics shows that almost all of the spring wheat,oats and barley crops in Minnesota have already been harvested.  The average for this time in mid-August is for about a third of the spring wheat harvest to be completed.  Row crops are moving quickly toward maturity--the crop report shows about a quarter of the corn crop is in the dent stage, half the sweet corn crop has been picked and about a quarter of the canola crop is out.  But we still need rain -- half of Minnesota's topsoil is rated short or very short of moisture.
