July corn opened 5 cents lower on the session at 586 and established an early range of 583 1/2 to 591. Corn traded in a narrow range below Friday's closes in both the July and December contracts in early action today. Traders indicate that the weakness was due to ideas that planting progress in corn will stand at 75-80% on this afternoon's Crop Progress Reports and that further good progress this week will result in the crop being fully planted at a near normal rate by next week. This in turn could result in a yield above the figure used on the USDA's most recent Supply and Demand Report. They had pegged the average US yield at 1 bushel below the trend line due to expectations of late planting. This week's export inspections were 27.318 million bushels. Weekly totals of 48.977 million are needed to reach the USDA's projected export total for the current crop year. Total inspections to date stand at 70.1% of the projected total compared to a 5-year average of 66.1%
