tailieunhanh - Vertical distribution of micronutrient cations in the Orange (Citrus reticulata) orchard, Tamenglong district, Manipur (India)

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 to mg kg-1 , to mg kg-1 , to mg kg-1 and to 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 % of the soil sample. Multiple regression analysis showed that the DTPAextractable 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 , and % in the surface horizon but their influenced were significant only by soil OC and silt. | Vertical distribution of micronutrient cations in the Orange (Citrus reticulata) orchard, Tamenglong district, Manipur (India)
