Abstract:
A study was conducted to evaluate the fertility status of soils of twelve different villages of Pub Nalbari block of Nalbari district, Assam, India. A total of 300 numbers of surface soil samples (0-15 cm depth), comprising of 25 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, available nitrogen, available phosphorus, available potassium, available sulphur and available zinc and boron using standard procedures. Based on calculated nutrient index value soil fertility rating as low, medium and high for each fertility parameter was done. Results revealed that pH of the all soils of study area was found in the acidic range and majority (43%) of the samples lie in the very strongly acidic (4.5 to 5.0) range. Electrical conductivity was normal (<1dS/m). Soil organic carbon varied and recorded in low (15%), medium (57%) and high (28%) category. Nutrient index value for available nitrogen, phosphorus and potassium was low to medium range. Available sulphur was high to medium in the soils of the study area and zinc content was found low to but available boron was recorded low for most of the soil samples.
