Abstract:

Vertical distribution of DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) and its correlation with several physico-chemical properties of soils in fifteen orange orchards of Tamenglong district, Manipur was studied. Most of the upper soil layer had higher DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) content than the lower horizons. In the profiles, the value of DTPA- extractable micronutrients (Fe, Cu, Mn and Zn) ranged from 18.62 to 45.12 mg kg-1, 0.12 to 1.26 mg kg-1, 3.42 to 44.33 mg kg-1 and 0.16 to 1.36 mg kg-1, respectively. The DTPA-extractable Fe and Mn were found to be sufficiently available in all the profiles whereas, Cu was found adequate in most of the surface horizon (0 - 20cm) in most of the soil samples. However, Zn deficiency occurred in 55.56 % of the soil sample. Multiple regression analysis showed that the DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) content in the soils were influenced by pH, OC, EC, Mg, silt, K and clay to the degree of 50.1, 25.7 and 60.5 % in the surface horizon but their influenced were significant only by soil OC and silt.
