Flooding (Excess Moisture) in Soybean
Extended periods of flooding may result in injury or complete death of soybean, depending on the duration of flooding and temperatures during flooding. Symptoms associated with extended flooding include stunted and yellow plants. Flooding may also result in silt and residue from previous crops on the plants which will reduce photosynthesis and limit crop growth.
Crops that are exposed to flooding are more susceptible to various root rot diseases. Injury from flooding can appear similar to symptoms caused by charcoal rot, Thielaviopsis root rot, or nematodes.
