    Abstract

    Submerged soils differ considerably from their arable counterparts. Lack of oxygen and the reduced state of submerged soils cause this. Submerging a soil under water triggers a series of physical, chemical and biological changes that greatly affect the dynamics of soil fertility and its use for growing crops such as wetland rice. Due to lack of oxygen, the nitrogen (N) mineralization process in submerged soils stops at ammonium production and nitrification is at low ebb. Most rice soils, especially those in the tropics are rich in iron (Fe). Redox cycling of Fe exerts a wide-ranging influence on the biogeochemistry of submerged rice soils and aquatic sediments where Fe is abundant. This article critically assesses the literature on the role of reducible Fe, which participates in redox reactions in submerged
