Abstract:

The depth wise distribution of DTPA-extractable micro-nutrient cations (Zn, Cu, Fe and Mn) and their relationship with other soil properties were worked out in twenty eight (28) typical soil profiles of paddy fields of Thoubal and Bishnupur district, Manipur. DTPA-extractable Zn, Cu, Fe and Mn content were higher in the surface soils than the sub-surface soils and varied from 0.27 to 1.48, 1.00 to 8.00, 17.00 to 287.00 and 6.00 to 141.00 mg kg-1, respectively. DTPA-extractable micro-nutrient cations were well sufficient in the surface layer (0 – 20 cm) of all the soil profiles. Multiple regression analysis indicated that the DTPA-extractable Zn, Cu, Fe and Mn content were influenced by pH, EC, CEC, OC, N, sand and clay to the degree of 0, 44, 24 and 82, respectively, however, their influenced were insignificant.
