“…The available Cu content in soil of Jhargram district showed a significant and positive correlation (r= 0.168, P= .01) with soil organic carbon content. Similar findings were also reported by Tur et al [35] and Aich et al [36]. This is may be due to formation of soluble chelates of Cu by the organic matter which increases Cu availability in soil.…”

Aims: This investigation is aimed to conduct a delineation study to know the spatial distribution of available cationic micronutrients (Zn, Cu, Fe and Mn) in red and lateritic soils of Jhargram district of West Bengal and their relationship with soil chemical properties. Study Design: Spatial distribution. Place and Duration of Study: Geo-referenced 253 surface soil (0-15 cm depth) samples were collected from eight blocks (Gopiballavpur- 1, Gopiballavpur- 2, Nayagram, Jhargram, Sankrail, Jambani, Binpur- 2 and Binpur- 1) of Jhargram district of West Bengal, India during 2017- 2018. Methodology: Grid based detailed block wise soil sampling has been carried out in long term crop growing fields of Jhargram district of West Bengal.The collected soil samples were analyzed and their cationic micronutrient status were depicted through nutrient index and fertility maps. Geographical information system (GIS) is an important tool to identify the risk areas. In our study Arc Info GIS has been used to prepare the spatial distribution maps of available cationic micronutrients and soil chemical properties (pH and organic carbon) of different blocks of this district. Results: The pH, organic carbon content, available Zinc, Copper, Iron and Manganese content in soils were in the range of 3.68-7.6, 0.15-2.01 (%), 0.56-5.52, 2.4-11.76, 31.6-208.4 and 6.32-99.74 mg kg-1, respectively, with the mean value of 4.97,0.64 (%),2.21, 5.75, 114.68 and 41.87 mg kg-1 respectively. The lowest zinc content has been recorded from the soils of Gopiballavpur- 2 block. Conclusion: The calculated NIV and spatial distribution maps clearly indicated that there is no deficiency of Iron, Manganese and Copper in this region. Zinc status did not resemble with other cationic micronutrient status which was mostly low to medium with some patches of deficiencies. Soil pH has significant positive relation with Iron. Copper has significant positive relation with soil organic carbon.

“…442). Similar results were given by Aich et al 42 Available copper and organic carbon correlated significantly and positively (r= 0.785**). This can be explained by considering that organic matter increases the availability of copper by forming soluble complexing agents which decreases the formation of insoluble copper complexes.…”

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*).

“…Based upon the coefficient of determination between micronutrients and soil properties, a positive correlation was observed between organic carbon and Mn, Cu and Zn. The CaCO 3 content in the soil showed negative and significant correlation with available Fe and Mn [8].…”
