This week finds Iowa just slightly above the seasonal average in degree day accumulations. The lack of rainfall in many parts of Iowa has been a recent topic of discussion. Posted here are the precipitation deficits by crop reporting district from May 1 through June 11. With the exception of northeast and east central Iowa, it has been a dry start to the growing season. The question, "how critical are the current deficits to the growing crop?" is best answered, "it depends."
