| In my area of east Illinois I was on the western edge of the July rain event. 3.5 inches in my area. West of me quickly dropped to 2 inches or less. East of me. 4 to 5 inches. Clay to silty clay loams in my area. Good years can be 230 or more. Typically, low ground tile, high ground not much. without large rain event at tassel or before. low ground will stay more green and longer than the lighter high ground. Through the field yield will look something like 250 low ground declining to 210 on the hills, giving 230 average.
Now add 3+ inch rain event that comes slowly allowing both high ground and low ground to go to max saturation. Denitrification happens to both the low and high ground. Here locally with corn planted from mid April to late May all showing the same thing. The low usually best ground is giving up first as well any seep or broad untiled areas. This is an excess rain event that is rare for our area. 20 miles west the normal high ground turning first is evident, but anywhere 3 inches or more in the July event is showing this phenomenom. Yield loss for these areas? Guessing 10 to 30 bushel normal average loss, with some higher losses and well tiled fields with lower losses.
Maybe someone here can quantify it better. | |

Hurricane rain in July, too much of a good thing?
