A review of electrochemical changes in submerged soils

Flooded soil causes changes in the properties of the soil because of physical reactions between the soil and water and the biological and chemical process set in motion as a result of excess water. However rice (Oryza sativa L.) root systems play an important role in uptake of water and nutrients from soil (Yang et al., 2004). Soil reduction resulting from flooding can change availability of nutrients to plants via change in chemical species (e.g., increasing solubility of Fe) (Pierce et al., 2010). The most important change is the conversion of the root zone from an aerobic environment to an anaerobic or near-anaerobic environment.
