Under waterlogging conditions, oxygen depletion in the soil injures roots, limiting their ability to uptake nutrients and water. In response, plants close their stomata to prevent water loss, leading to a subsequent reduction in photosynthesis. Common symptoms include wilting, stunted growth, and yellowing leaves. If the stress persists for an extended period, plants may eventually[Read More…]
Irrigation and Drainage
This week, several regions of Indiana experienced excessive rainfall due to the remnants of Hurricane Beryl passing through the state. The heavy rain caused flooding in some vegetable fields. When soil water levels surpass optimal requirements, oxygen is depleted, leading to waterlogging stress for the plants. Figure 1 displays the varied responses of different crops[Read More…]
After the heavy rains in the past a few days, flooding/waterlogging injury stands out in my farm visit this week. Regardless of tomato or cucumber, the injured plants showed leaf yellowing that occurred 2 to 3 days after waterlogging (Figure 1). The yellowing leaves are a result of chlorophyll loss, which is associated with N[Read More…]
With the record-setting rainfall we’ve seen over the past month, flooding of fields is very widespread (Figure 1). Fields that have experienced flooding present growers with difficult management choices. Flooding is defined (per FDA) as the “flowing or overflowing of a field with water outside a grower’s control.” Flooding is associated with streams, creeks, or[Read More…]
