Profile distribution of DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) and their relationship with various soil physico-chemical properties were studied in twenty jhum land of Chandel district of Manipur. Soils of the upper horizon had higher content of DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) than the lower horizons. In the profiles, the value of Fe, Cu, Mn and Zn varied from 10.27 to 159 mg kg-1, 0.04 to 3.21 mg kg-1, 0.44 to 38.67 mg kg-1 and 0.10 to 1.67 mg kg-1 soil, respectively. The contents of DTPA- extractable Fe and Mn were sufficient in all the profiles, while Cu was adequate the surface layer (0 – 20 cm) in majority of the soil samples with the exception of a few samples. However, 51.25 per cent soils were deficient in DTPA-Zn content in the surface layer. Multiple regression analysis showed that the DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) content in the soils were influenced by pH, OC, Mg, K, EC, CEC and clay to the degree of 54.5, 28.8, 42.4 and 46.2 per cent in the surface layer, however, their influenced were significant only by soil OC, Mg and pH in all the profiles.
