Some areas in the state have received over 9 inches of rain in the last 7 days. These rains have left many crop fields flooded/ponded or fully saturated. Fully saturated and flooded soils are deficient of oxygen because the soil air spaces are displaced by water. Questions are being asked if the crops submerged or partially submerged in flood water will survive. The probability that such crops will survive depends on the type of the crop, crop growth stage, soil type, temperature, and the duration of the ponding/saturation.
