Chilly, Windy Conditions and Spotty Rains
Wisconsin had 5.2 days suitable for fieldwork for the week ending October 18, 2020, according to the USDA’s National Agricultural Statistics Service. Chilly, windy conditions and spotty rains interrupted fieldwork in some areas this week. Overnight lows fell into the 20s on multiple nights with many reporters noting a killing frost. Areas of northern Wisconsin received up to 2 inches of snow on Saturday though it melted off quickly. Precipitation was welcome where received, helping germinate fall plantings and bulk up hay stands for the winter. The corn and soybean harvests made rapid progress in between precipitation events. Frosts and freezes helped to push late-planted corn toward maturity. Fall tillage and manure spreading continued. The potato harvest was nearing completion.
