    Author : Dennis Dennis Wilson; [2017]
    Keywords : Key Words: Soil Concentration; Soil CO2 production; Soil Respiration; Seasonal variation.;

    Abstract : Forest soil is an important source of atmospheric CO2. Emission of CO2 from soil is the result of respiration of plant roots and soil organisms (Autotrophic and Heterotrophic respiration). This soil CO2 emission has a variation throughout the year with maximum emissions being in the summer. READ MORE
