WASHINGTON, D.C.(DRGNews)- South Dakota farmers have started harvesting their corn and soybean crops, but the combines may not be filling up very quickly.

USDA meteorologist Brad Rippey says according to this week’s USDA National Ag Statistics Service update South Dakota’s corn crop is still the worst in the nation.

He says South Dakota’s soybeans aren’t doing much better.

Rippey expects the US sunflower harvest to finish fairly quickly.

Rippey says across the country, winter wheat planting is ahead of average pace.

With 18% of South Dakota’s sorghum crop harvested, USDA NASS reporters say 66% of it is rated poor to fair. Pasture and range conditions rated 80% very poor to poor.
