With the significant rainfall the area saw beginning a couple weeks ago (> 2.6 inches between May 21 and 28), plus almost another inch of rain between June 1 and now, corn is beginning to show signs of N deficiency. Some fields are showing areas of stunted, light green plants, and some are exhibiting uneven emergence. This is not across the board, however, and some fields look very healthy. This week, I have seen little to no ponding in fields.
