Alluvial soils form within the river floodplains. The conditions of soil formation for alluvial soils determines by the specifics of the ratio of biological and geological circulation of substances, rapid development of vegetation, and high biogenicity. They differ significantly from the soils of watersheds in their properties, genesis and use. Iron is requires careful study as one of the chemical elements that are necessary for the life of the biota and as one of the elements that determine the properties of soil. Iron, as a chemical element with variable valence, is in oxidized and reduced forms in soil. Their determination carries out in an acidic extract using α-α-dipyridyl by the colorimetric method. The results indicate that there is a connection with the iron content of the soil located on the floodplain, with the depth.
