It’s a sign that spring has not yet taken hold in the area. Iowa State University Extension and Outreach Agronomist Leah Ten Napel says planting conditions are still not ideal. She says normally, soil temperatures should be 50 degrees or rising, but that’s not yet the case. The Iowa Environmental Mesonet says soil temperatures in Plymouth County have been in the mid to upper 40s They are expected to fall to near 40 degrees this weekend as colder weather moves in. Ten Napel says corn and soybeans do not germinate until the soil temperatures are 50 degrees F.
