Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This study investigates the relationship between soil organic carbon (SOC) content and carbon density variations along altitudinal gradients, slope aspects, and different forest types in Nahi Gewog, Bhutan. The study aims to understand how SOC is influenced by elevation, slope aspect, and forest type, and how these factors contribute to the overall carbon density of the soil.

• The role of soil as a carbon pool in the global carbon balance and its importance in mitigating climate change.
• The influence of elevation, slope aspect, and forest type on soil organic carbon density and distribution.
• The relationship between soil bulk density and soil organic carbon content.
• The impact of soil depth on soil organic carbon density.
• The potential for soil carbon sequestration in Bhutan and the importance of understanding carbon dynamics in the Himalayan region.
