6-12-12 (St. Paul, MN)  --  You can probably tell by looking at the fields -- Minnesota's corn crop is way  of ahead of schedule.  The latest U-S-D-A Crop Report shows corn averaging over a foot in height while most soybeans have sprouted and are on their way up.  Another promising sign for Minnesotans -- more than two-thirds of the state's sweet corn crop has been planted.  Soil moisture dried a bit in the past week after very warm temperatures across most of the state.
