The USDA reports cooler than normal temperatures covered the state last week, slowing Illinois corn growth and delaying the emergence of both the corn and soybean crops.

The weekly crop progress report shows farmers made some progress with corn and soybean planting. Eighty-seven percent of the corn is in the ground and 39-percent of the beans are planted. The numbers are a little better in western Illinois, where farmers have 90 percent of the corn and 47 percent of the soybean crops planted.

Sixty-eight percent of the corn has emerged in the western region compared to the state average of 62 percent. Five percent of the region's soybean crop is emerged, which is slightly ahead of the 4-percent statewide average.

USDA crop statistician Brad Schwab says farmers are still playing catch-up with their corn planting, and now re-planting is necessary in some places, especially southern Illinois.

The USDA reports an average of 3 and a half days suitable for fieldwork last week, and 98 percent of the state's soil moisture content is rated adequate or surplus.

The temperature in all nine of the state's crop reporting districts was more than 7 degrees below average at 58.2. Western Illinois received 8-tenths of an inch of rain last week, trailing only central Illinois, which received 9-tenths. Both amounts are above average. The state average was less than a half-inch, which was 47-hundredths of an inch short of the norm.

Last year at this time, 99-percent of the state's corn and 86-percent of the soybeans had been planted.
