A study was conducted to evaluate the fertility status of soils of five different villages of Lahowal block of Dibrugarh district, Assam, India. A total of 100 numbers of surface soil samples (0-15 cm depth), comprising of 20 composite soil samples from each site, were collected. The collected soil samples were air dried, sieved and analyzed for different fertility parameters viz., soil pH, electrical conductivity, organic carbon, primary nutrients (available nitrogen, available phosphorus, available potassium), available sulphur and micronutrients (available zinc and boron) using standard analytical methods. Soil fertility rating as low, medium and high for each fertility parameter was done by calculating nutrient index value. Results revealed that pH of the all soils of study area was found in the acidic range and majority (51 %) of the samples lie in the very strongly acidic (4.5 to 5.0) range. Electrical conductivity was normal (<1.0 ds/m). Soil organic carbon was medium to high. Nutrient index value for available nitrogen and phosphorus was low to medium range. Available potassium content was low and sulphur and zinc content was found medium in all the samples but available boron was in low to medium index level.
