As farmers prepare to plant their corn crop this spring they are running into some issues because of low soil temperatures.

Following cold and wet weather in Iowa, the state’s corn planting season has been significantly delayed. The pushing back of planting shortens the optimal yield window for the year. Only 9 percent of Iowa’s corn crop has been planted according to a May 2 Iowa Department of Agriculture and Land Stewardship. The average by this time of year is 42 percent of the crop.

State Climatologist Justin Glisan told Iowa Capital Dispatch early planting this year was first stalled in April because of low temperatures five degrees below average. He said 2022 had one of Iowa’s top 15 coldest winters.

Soil temperatures need to be at least 50 degrees to plant corn seed that is likely to sprout. Soil temps have mainly stayed in the 40s this spring. The lack of planted crops will impact supply moving forward this year.
