摘要

The morphology and micromorphology of paddy soils under different soil moisture regime and groundwater table of Northern Iran, were investigated. Aquic conditions in soils are often associated with redoximorphic features. The depths at which the features occur are often used as an indicator of the location of the seasonal water table. Morphological and micromorphological characteristics could be used to identify the hydromorphism degree of soils and their properties. In this study, morphological and micromorphological characteristics of paddy soil samples with different water table depth and drainage were investigated. Thirty-nine undisturbed blocks of soil were taken. Thin sections were observed with a polarized microscope and described according to thin section interpretation. This study demonstrated the extensive pedogenic changes and micromorphological evidences. Studied soil samples are exposed to alternative fluctuations with water saturation in different time. The various type of iron and manganese oxides show the difference of environment and their movement and formation are the most important factor to form hydragric anthrosol. This study demonstrated that moisture regimes in soils with anthraquic saturation can be characterized in the same way as in soils with either episaturation or endosaturation. Also, the effect of irrigation water on pedogenesis with respect to saturation, reduction and redoximorphic features was greater than that of the shallow groundwater.
