I was catching up on some reading when I came across this picture.

It is from the October issue of Iowa Farm and Ranch. The caption reads "Fall colors are abundant throughout western Iowa, with corn and soybeans maturing and drying. Vibrant green in the grass and tree leaves make a beautiful contrast of colors. (Photo by Bruce A. Binning)" .
I think they may have a misprint int the caption, the corn and soybeans are "dying" not maturing and drying. I have seen lots of this premature yellowing/dying of crops this year. Hill tops and side hills all over Iowa looked like this.
When crops die early, they don't make it to full matruity and yield is lost. The reasons can be many for the crop dying early but there is only one solution, proper crop nutrition. Ensuring that you have proper soil pH, and proper calcium, sulfur, zinc, and boron levels will help your crop go the distance.
If you have seen your crop "maturing earlier", poor stalk quality, and high disease pressure, give us a call. We can help.
