Heavy rainfall (1-2 inches of rain) events were reported for some areas of Ohio last week. Heavy rainfall can negatively affect planted and emerged fields, planted and non-emerged fields, and yet-to-be-planted fields. If you are in one of the areas with concerns about heavy rainfall, below is a summary of topics that one should consider (Table 1).
Table 1. Topics, considerations, and takeaways for corn and soybean fields are affected by heavy rainfall this season.
The bottom line is that seed damage due to abiotic factors can affect seedling vigor, plant growth, and crop establishment, ultimately reducing crop stands and yields. We recommend weighing the above considerations if you are affected by heavy rainfall this crop season.
