The weather station near Estherville in Emmet county has received 0.14 inches for the month of June. However, parts of Dickinson, Clay, Emmet, Palo Alto, Kossuth, and Winnebago remain dry.

A hailstorm last Tuesday evening left over 30,000 acres damaged, with a high percent totaled, mostly in Plymouth County. Cupping is very visible on a lot of fields at this time, and most are uniformly injured across the entire field. Saw some K deficiency in a few fields this week – likely due to the inability to take up the nutrients under this environment, more than a case of low soil tests. Soybeans V5 to V7 – most beginning to bloom (R1, some R2). From 0.2 to a half inch might have been more common there. The area to the north received less, and likely needs it more.

Joel DeJong (Region 1): “An inch or more of rain fell in the southern half of the area I serve during the past week, with a few scattered neighborhoods getting up to 3 inches. Read on to see what's happening in different regions across the state.

In addition to the rain (lack of, too much, or just enough) and hail, herbicide injury in soybeans and potassium (K) deficiency are some of the issues ISU Extension field agronomists have observed this past week. The rain also brought some hail, which caused some pretty significant damage not just to crops but property as well. While some much-needed rain did come this past week it seems that the drier areas continue to miss out or get minimal rainfall and the wetter parts of the state keep getting wetter.
