Abstract:

Profiles of paddy and associated non-paddy soils of Jorhat (P1, NP1), Golaghat (P2, NP2), Sivasagar (P3, NP3) and Dibrugarh (P4, NP4) districts of Assam were investigated for different forms of aluminium (Al): total (Alt), dithionite extractable (Ald), pyrophosphate extractable (Alp) and oxalate extractable (Alo) in the clay fraction. Total Al (Alt), dithionite extractable Al (Ald) and oxalate extractable Al (Alo) in clay fraction was slightly higher in paddy soils as compared to non-paddy soils whereas pyrophosphate extractable Al (Alp) showed a reverse trend. Ald formed major portion of total aluminium content in clay fraction (Alt) followed by Alp and Alo in both paddy and non-paddy soils. Crystalline aluminium oxide (Ald-Alo), amorphous inorganic (Alo-Alp) and silicate aluminium (Alt-Ald) in clay fraction was found to be higher in paddy soils than non-paddy soils. Also, irrespective of the land use, the content of different forms of Al in the clay fraction was irregular with depth. Ald/Alt was found to be slightly higher in non paddy soil than that of paddy soil. Different fraction of organic carbon and the content of clay had a strong influence on the distribution of forms of Al in the clay fraction of soil. The results also revealed that there was equilibrium in different fractions of this element.
