DES MOINES, Iowa (AP) – Iowa farmers are being urged to be careful as the harvest kicks into high gear. Dry and windy weather has increased the fire risk. Some law enforcement officials have asked farmers to stop harvesting until conditions improve. The weekly crop report on Monday shows 91 percent of the corn crop is now mature with 12 percent harvested for grain or seeds. Both are behind last year but ahead of the average. Fifty-eight percent of the corn is in good to excellent shape. Twenty-one percent of the soybean crop has been harvested, which is behind last year and the average. Sixty-five percent of the soybeans are in good or excellent condition. State climatologist Harry Hillaker says last week was the ninth week of the past ten with below normal precipitation.
