Iowa farmers have hit a bit of a speed bump with widespread frost and colder temperatures.Iowa State University Extension Field Agronomist Paul Kassel said he hasn’t had any reports of damage but the cooler weather has put a damper on growing progress.“We’re kinda losing out here on leveraging our early planting. We like to plant early to kind of extend the growing season and increase the amount of time during the summer months when we can fill the kernel and the pods that’s probably the overall bigger concern,” said Kassel.
