Inherent Factors Affecting Soil Respiration
www.nrcs.usda.govInherent Factors Affecting Soil Respiration Inherent factors such as climate and soil texture impact soil respiration. Soils that have lower porosity also have a lower respiration rate. Soil respiration rates are also dependent on dynamic soil factors, including SOM content, temperature, moisture, salinity, pH, and aeration.
