In spring 2016, northeastern Alabama and northwestern Georgia experienced a dry spell that was nearly a month long. It occurred right during the pollination stage for corn there. The lack of moisture led to spotty pollination because the silks were too dry to capture pollen. Some fields were total losses, and others had such poor stands that they were chopped for animal feed. This year, farmers in the Midwest are experiencing drought, and in some cases, the dry conditions have also affected their corn pollination and yield. Here is a story from AgWeb describing how a Missouri farmer discovered that he had lost most of his corn crop.
