(Radio Iowa) – Farmers worked through some snow flurries and cold, wet weather last week to continue the push to close the harvest season. The U-S-D-A crop report shows farmers in south-central Iowa still have more than 20 percent of their corn to harvest — but overall 91 percent of the corn is out of the fields. That is four days ahead of the five-year average. The report says soybean crop harvest is virtually complete at 97 percent. While rain and snow did hinder the harvest a bit — the report says it did help slightly improve soil moisture levels.
