Many corn and soybean farmers across the state are waiting for soils to warm up before planting.  University of Minnesota Extension Agronomist Jeff Coulter says soil temps at three-to-four inches deep should be at least 50 degrees and trending up:

“So if that soil temperature drops to around 40 degrees or lower within one to two days after planting, that’s not a good thing because we can have an imbibitional chilling injury occurring, and that can cause problems with emergence.”

Coulter says the 48 hours post-planting are critical.
