The Crop Watch '14 field is greening up and growing. However, a couple of spots worth watching have already shown up. That probably could describe conditions in many of your field. Now is the time to document where those spots are and see how they develop.
Are they wet spots? Are they locations where something malfunctioned and the area wasn't fertilized the same? Are there patterns? It may be too early to answer any of these questions, but it's not too early to begin paying attention.
Crop Watch 5/26: Corn Up and Trying to Shake Off Yellow Color
This week the Crop Watch '14 field turned the corner in growth and in developing a much greener color. However, after considerable rain that helped most of the field, low spots, fortunately there aren't many in this field, began to show up.
Plants are still yellowish and stunted in the lowest part where water may have sat. They gradually improve in condition as you move up the natural drainage way. Fortunately, it's a small area so it won't impact the field little, if at all. It's one of those areas which may show up on the yield map at the end of the season, especially if more heavy rains cause saturated soils there periodically.

More intriguing, in a couple of areas a pattern of six- to- eight rows wide by maybe a 100 feet long seem to be appearing. The corn to the row is slightly shorter, slightly more yellowish at this stage. Was there a difference in a fertilizer application? Is there a difference from the past?
It's too early to answer those questions because it's not clear yet whether the pattern is isolated or may repeat across the field. It's one of the things we'll be watching for as the corn begins to develop further.
