Abstract: A study of the secondery and micro-nutrients on soils of Jajpur district, Odisha (India) was carried out to study the soil fertility and micro- nutrient status and their deficiency percentage of the district. Surface soils (0 to 20 cm) was investigated for diethylenetriaminepentaacetate (DTPA)- extractable Zn, Cu, Mn, Fe and hot water extractable B along with secondary nutrients and their deficiency and `multinutrient deficiency in 300 representative soils. The mean values for DTPA-extractable Zn, Mn, Cu, Fe and hot water extractable B were 110. 9, 68. 81, 2. 87, 0. 99 and 0. 40 mg kg-1, respectively. The mean values of some basic properties like pH, EC, OC of the Jajpur soils were 5. 52, 0. 12 (dS/m) and 0. 66%. As per critical limit prescribed, in the district S, Zn and B were found to be 40%, 26. 6 % and 73. 3% deficient Not only single nutrient but also multi nutrients deficiency was observed in the district i. e., S+Zn, S+B, B+Zn, B+Zn+S up to 10. 3, 32, 26, 8% respectively. Plant tissue analysis result showed that PSD with respect to S, B, Zn, Mn and Cu were 25. 7%, 51. 4%, 17. 14%, 5. 7% and 5. 75 respectively.
