Abstract: A study was conducted to assess the micronutrient status in the soils of seven different villages of Tengakhat block of Dibrugarh district, Assam, India. GPS based 140 numbers of surface soil samples (0-15 cm depth), comprising of 20 composite soil samples from each site, were collected. The pH of the all soils of study area was found acidic and majority (37%) of the samples lie in the strongly acidic (5.1 to 5.5) range. Electrical conductivity was normal (<1.0 ds/m) and soil organic carbon content varied from low to high (0.34 to 1.09) with average value of 0.68. The available soil micronutrients as iron, manganese, copper, zinc and boron status was found 18.98 to 107.59 mg/kg, 6.98 to 42.99 mg/kg, 0.88 to 4.92 mg/kg, 0.21 to 1.86 mg/kg and 0.21 to 0.87 mg/kg respectively with mean value of 73.97 mg/kg, 22.78 mg/kg, 2.57 mg/kg, 0.82 mg/kg and 0.50 mg/kg respectively. All the soils of the study sites contain high amount of available iron, manganese and copper. Majority of the soil samples contain sufficient amount of zinc (67%) and boron (54%).
