“…Considering 0.20 mg Cu kg -1 soil as critical level (Lindsay and Norvell, 1978), all the soils were sufficient with available Cu. Similar findings were also made by Sen et al, 1997, Gupta et al, 2003, Verma et al, 2007, Athokpam et al, 2013, Athokpam et al, 2016and Athokpam et al, 2018. Highest variation in Cu was noticed in soils of Dhenkanal with a standard deviation of 1.66.…”

“…The content of these nutrients decreased with increase in depth in most of the studied profiles. Similar results were also reported by Athokpam et al, (2016) and Athokpam et al, (2018) in the soils of Ukhrul and Tamenglong districts of Manipur, respectively.…”

“…The surface layer soil contained more available Fe than those in lower depth and showed a decreasing pattern along with depth except for few samples. These findings are in agreement with earlier works of Sen et al, (1997), Gupta et al, (2003), Sharma et al, (2003), Pati andMukhopadhyay (2011), Athokpam et al, (2013), Athokpam et al, (2016) and Athokpam et al, (2018).…”

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.

“…Sharma et al 33 reported that the content of zinc and copper were, in general, higher in the surface layers and decreased with depth. Athokpam et al 29 observed that the DTPAextractable copper content was higher in the surface soils and decreased gradually in all the profiles. Similar results were also reported by Gupta et al 30 and Verma et al 31 .…”

“…Satish et al 28 reported that all the pedons showed decreasing trend with depth which might be due to higher biological activity and organic carbon in the surface horizons, the higher content of available manganese in surface soils was attributed to the chelating of organic compounds released during the decomposition of organic matter left after harvesting of crop. Athokpam et al 29 reported that the surface soils contain higher manganese value and decreased with increase in depth 30 , 31 , 32 , . Sharma et al 26 reported that DTPA extractable manganese decreased down the depth of pedons.…”

The present study was undertaken to assess the vertical distribution of DTPA-extractable micronutrients viz. zinc, copper, iron and manganese in relation to soil properties in five selected soil profiles, one each from Sainthia, Suri II, Rampurhat II, Md Bazar and Nalhati I block of Birbhum district of West Bengal. Collected soil samples were analysed for pH, electrical conductivity, organic carbon, textural class (% sand, silt, clay) and DTPA-extractable micronutrients using standard analytical methods. The soil texture varied from silt loam to silt. Based on the fertility ratings, pH of the profile soils was strongly acidic to neutral, showing increasing trend with depth. Its value ranged from 5.012-7.121. Electrical conductivity was found in normal range. Low to medium organic carbon content was found and its distribution was found decreasing with increasing depth. Iron, manganese and copper were estimated to occur above critical level, whereas low to medium available zinc was found. The available zinc, iron, manganese and copper contents in soils ranged from 0.264-1.618 mg/kg, 5.158-51.820 mg/kg, 1.788-20.720 mg/ kg and 0.324-3.364 mg/kg respectively. In general, all the micronutrients show decreasing trend with increase in depth. The pH of the collected soil samples showed significant and negative correlation with available iron (r=-0.603*) and manganese (r=-0.524*) whereas pH correlated nonsignificantly and negatively with available zinc (r=-0.343) and copper (r=-0.484). Soil organic carbon showed significant and positive correlation with all the micronutrients. Non-significant and negative correlation was found between electrical conductivity and available micronutrients except available iron which showed significant and negative correlation with electrical conductivity (r=-0.560*).
