I was up in Michigan this past weekend visiting my mom and experienced some cold temperatures that did not feel at all like late May. In areas farther west and north, they even had frost in some locations, the third latest ever at those spots. Many farmers there are still assessing the damage from the freezing conditions, but this AgWeb article describes some of the problems that Iowa farmers experienced from the frigid conditions. I was interested to read that no-till soybeans did worse than tilled fields, since usually no-till planting conserves moisture in the soil and preserves soil structure.
