Clay illuviation in calcareous soils of the semiarid part of the Indo-Gangetic Plains, India



Clay illuviation in calcareous soils of the semiarid part of the Indo-Gangetic Plains, India



Geoderma 115(3-4): 177-192



In view of diverse understanding on the movement and accumulation of clay particles in calcareous parent material, a micromorphological study on 28 Alfisols of the semiarid part of the Indo-Gangetic Plains (IGP) was undertaken. The study indicates that the identified clay pedofeatures are typically of the type "impure clay pedofeatures" which have resulted from the impairment of the parallel orientation of the clay platelets induced by dispersion of both clay and silt size layer silicates in slightly to highly sodic environment. The study also indicates that the illuviation of clay particles and their subsequent accumulation in the Bt horizons have occurred in sodic environment caused by the precipitation of soluble Ca (super 2+) ions as calcium carbonate (CaCO (sub 3) ), thus discounting any role of soluble Ca (super 2+) ions and the presence of CaCO (sub 3) in preventing the movement and accumulation of clay particles. The study thus suggests that the formation of impure clay pedofeatures and pedogenic CaCO (sub 3) are two pedogenic processes occurring simultaneously in soils of the IGP as contemporary pedogenic events in the semiarid climate since the last 4000 years B.P.
