We began this season with the best-laid plans for our corn crop. April weather provided us with the optimism we were all looking for, but since then, it’s been difficult to keep our head above water — literally. As you know, 2017 has proven to be one of the wettest growing seasons on record for Ohio, with some areas receiving over 20 inches of rain throughout the month of June and similar amounts in July as well. The saturated growing season has resulted in much of our corn experiencing shallow and weak root systems, nitrogen (N) loss, and even impacted pollination in some areas. While some well-drained fields may have had sufficient nitrogen available to the plant, excessive rainfall moved the nitrate nitrogen below the concentration of roots — making it inaccessible as well.
Stalk strength will likely be a concern for some fields as we head into harvest. Not only has the wet weather led to significant N loss due to leaching in lighter soils and DE nitrification in heavier soils, but corn hybrids are also changing.… Continue readingRead More »
