Determination Of CO2 Emissions

INTRODUCTION

Soil organic matter (SOM) contains more carbon than the atmosphere and terrestrial vegetation combined and therefore plays a crucial role in the global cycling of carbon (Figure 1).

Soil organic carbon (SOC), the primary component of SOM is a dynamic matrix and can be either a net sink or a net source of greenhouse gases (GHGs) depending on its management.
