Hydromorphic soils can be identified by the determination of hydromorphic index (HI), particle
distribution ratios and CEC/ clay using details soil survey database followed by their appropriate classification in USDA Soil Taxonomy. Results of the study indicate that soils were dark gray in matrix colour with
occurrence of nodules of iron (ferrous and manganese manganous) in reduction phases at a depth below 18
to 22 cm along with redoximorphic depletions at a depth below 42 to 59 cm in lower piedmonts and older
alluvial plains. Hydromorphic index (HI) varied from 20.6 in soils of older alluvial plains to 4.5 in soils of
active alluvial plains following the order as Older alluvial plains (20.6) > Lower piedmont (17.6) > Older
meander plains (5.8) > Younger alluvial plains (5.5) > Active alluvial plains (0.45). These index exhibited
significant relationship with soil physical and chemical properties. In these soils, the rate of accumulation of
organic matter tends to exceed the rate of its decomposition. The criteria considered for confirmation and
establishment as hydrmorphic soils could be a useful information for management of these soils for better
productivity and land uses.
