Two weeks ago I heard of 10 acres of corn near us that was planted. This past week we saw a huge increase in corn planting, with a few rolling May 12 and others following as the week progressed. While we had “only” .8 of an inch of rain this past week it took a while to dry, with temperatures in the 50s for most of the week.
The week of May 17 we saw slow drying, until May 14 when we were in the 70s with plenty of sun and wind. Our corn ground along the river stayed wet until just before it rained the morning of May 17.
Planting conditions weren’t great for most who were in the fields. Several fields I walked had mud under a dry crust. A lot of fields I checked were fairly wet; tillage was being used to dry them. With all the planting going on it’s difficult to have a good idea of what percentage of the area were in the fields. But given the distance between planters I’m guessing something like 40 percent of corn is in the ground around us, and maybe 10 percent of soybeans.
I checked some corn that was planted in April to our south in Walworth County. Some of it was starting to emerge exactly 21 days after planting. There will be some replant in those fields, especially in areas that had water standing for a lot of that period.
I did have a chance before the rain to check one of the plots we put in. If it wasn’t going to rain I would have had them rotary hoe it with the corn, just not penetrating the crust made from all the rain. We did a couple of emergence checks where we flag corn as it comes out of the ground. Those should be interesting to watch on those early-planted fields.
