This paper aims to review some concepts on electrochemistry of wetland soils. The main electrochemical changes after inundation are a decrease in redox potential, an increase in pH in acid and a decrease in alkaline soils and increases in conductivity and ion exchange reactions. These modifications in the system might influence plant growth, by affecting the availability on toxicity of nutrients, regulating uptake in the rhizosfere.
