ABSTRACT
Background: Carbon and nitrogen, two basic components of organic matter, extend a significant effect on crop residue decomposition. Soil organic carbon is a key component of any terrestrial ecosystem. Any variation in its abundance and composition has a direct impact on soil aeration and water retention and ultimately ⁷plant growth. The soil productivity depends in part on soil and crop management practices that maintain, or increase soil organic matter C / N ratio. Objective: This study was conducted to determine the C/N ratio in soil of Tarai region of Uttarakhand, india. Materials & Methods: The contribution of organic carbon, total nitrogen and C/N ratio was examined in eleven sites of Tarai region of Uttarakhand. Soil samples were collected by digging at a depth of 15 cm using suitable tools. The organic carbon was determined by using Titrimetric determination method or Wet –Digestion method, and total nitrogen was determined by Kjeldahl method. Results: Nitrogen concentration and nitrogen containing compounds were observed in most of the experiment sites of Tarai region of Uttarakhand. Organic carbon content was remarkably low in this region. Resulting ratio of C/N was ranged between 3.65-8.75:1, which was significantly low to optimal ratio. Conclusion: Except few sites, the soils of Tarai region of Uttarakhand were very poor in nitrogen and nitrogen containing compounds. The C/N ratio was observed much lower than the global average. Further studies are needed to investigate the underline reasons of this state of affairs.
