Abstract: A study was undertaken to evaluate the available nutrient status of farmer’s field from Kanti block in Muzaffarpur district of North Bihar, India in the year 2014-15. By using GPS, the 53 soil samples were randomly collected at the depth of 0-15 cm as per standard procedure. The soil analysis showed that the pH value ranged from 8.15–9.08 with an overall mean of 8.57 reflecting slight to strongly alkaline soils. E.C. ranges between 0.15–0.92 dSm-1 and Organic carbon content of the soil varied from 0.42–0.51 per cent. The available nitrogen content of representative soil ranged from 111.99 to 137.50 kg ha-1 with an overall mean of 129.61 kg ha-1 and the overall nutrient index value of this soil was 1.0. Besides, available phosphorus was observed from 23.70 to 95.30 kg ha-1 with overall nutrient index value was 2.94 and available potassium content from 137.24 to 244.70 kg ha-1 with nutrient index value was 1.57. It indicates that the analyzed soils of concerned block were low in available nitrogen, high in available phosphorus and medium in available potassium. Though, the sulphur content of the soils ranged from 4.09 to 21.00 ppm with an overall mean value 10.83 ppm, whereas micronutrients i.e. available zinc and iron (DTPA-extractable) content of soil was ranged from 0.02 to 1.34 ppm and 9.42 to 31.78 ppm with an overall mean of 0.60 ppm and 18.93 ppm respectively, which indicate that the soils are sufficient in the micro-nutrients.
