COLUMBIA (AP) - Missouri farmers made progress in harvesting, following a week of mostly dry weather.  The Missouri Agricultural Statistics Service reports the lack of moisture caused pasture conditions to worsen in most areas.  The corn harvest is 57 percent complete, slightly ahead of last year and three days ahead of the five-year average of 50 percent. Corn condition is rated 19 percent poor to very poor, 28 percent fair, 39 percent good and 14 percent excellent.  The agency says the soybean harvest is slightly ahead of last year, and soybean condition is rated 29 percent poor to very poor, 34 percent fair, 30 percent good and 7 percent excellent.  Pasture conditions are rated 26 percent very poor, 25 percent poor, 33 percent fair, 14 percent good and 2 percent excellent.
