Soil Respiration: Concept and Measurement Methods

摘要

Soil respiration is the main element in the carbon cycle that makes possible for plants carbon plants to return in the atmosphere. The objective of this work was to present and discuss some aspects of the soil CO2 efflux. We defined herein, some terms associated to the soil respiration concept, we tackled some aspects regarding the influence of temperature, humidity and soil pH on soil respiration and we presented the principle of soil respiration measurement by using dynamic closed chamber system.
