How does salinization affect plants
WebNov 18, 2024 · Salinization is bad because it reduces water uptake in plants. Increased salts in the soil skew the concentration gradient in plants, reducing the osmotic potential of roots to take in water from the soil. With time, the plants will start to wither and, without intervention, die. Salinization also causes other problems such as: Ionic imbalance WebNov 21, 2024 · We evaluated the effect of seawater intrusion in coastal ecosystems on the freshwater invertebrate community and on leaf litter decomposition under realistic scenarios in six outdoor freshwater mesocosms containing fauna and flora, to which increasing volumes of seawater were added.
