SIOUX FALLS, S.D. (AP) - The row crop harvest in South Dakota is being slowed by cool, wet conditions. The Agriculture Department says in its latest crop and weather report that the sunflower harvest is 31 percent done, the corn harvest 63 percent complete and the soybean harvest 92 percent done. The soybean and corn harvests are close to the long-term average pace, but sunflowers are well behind. The report says that in addition to harvesting, South Dakota producers have been busy the past week moving hay and grain, moving livestock and preparing for winter.
