Soil respiration is the process by which microorganisms in the soil break down organic matter and release carbon dioxide into the atmosphere. This is a key component of the carbon cycle, as it is a major pathway through which carbon is transferred from the soil to the atmosphere. Soil respiration rates can be affected by factors such as temperature, moisture content, and the amount of organic matter present in the soil. Studying soil respiration is important for understanding the balance of carbon in terrestrial ecosystems and how it may be impacted by factors such as climate change or land use practices.
