dc.description.abstract | In view of scanty information about the position of charge in smectites for soils of Maharashtra in particular, and India in general an attempt has been made to locate seat of charge of some Vertisol clays by determining the reduced cation exchange capacity (CEC R) of smectitic clays. Six benchmark Vertisols from Maharashtra namely, Linga (P1), Loni (P2), Asra (P3), Paral (P4), Kalwan (P5) and Nimone (P6) from Nagpur, Yavatmal, Amravati, Akola, Nashik and Ahmednagar districts, respectively were chosen for the study. Fine clays were separated from the soils and their original CECs (CECUT) were determined by exchange with neutral normal MgCl2 followed by CaCl2 and BaCl2. Greene-Kelly test was performed by treating these clays with 3N LiCl. The Li-clays were also treated with the above metal chlorides in the same order to get the reduced CECs. Methods were formulated to calculate the actual CEC. The tetrahedral CEC decreased with increasing depth of soil for Linga, Asra, Kalwan and Nimone, whereas opposite trend was observed for Loni and Paral. The octahedral charge increased with depth for all except for Asra and Paral. The study indicated that cation exchange capacity determination appeared to be an accurate and less time-consuming approach to measure charge reduction. It can be used to locate seat of charge and also to study changes in the proportion of tetrahedral and octahedral charge during the pedogenetic processes of soil formation. | en_US |
