The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous ...

Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year ...

Soil respiration is the result of heterotrophic respiration (Rh) and autotrophic respiration (Ra), accounting for about 50%–75% of the total ecosystem respiration on land, which is crucial for the global carbon cycle and ...

The ground beneath our feet is exhaling. Steadily and without pause, through a process called soil respiration, plant roots and microbes release carbon dioxide (CO2) into the atmosphere.

Under field conditions, soil respiration consists of heterotrophic respiration by soil microbes and autotrophic respiration by plants. Temperature sensitivity (Q10) is a common method to describe proportional changes in soil ...

In paddy fields, water management creates long-term anaerobic conditions in which soil organic carbon (SOC) mineralisation is largely coupled with redox processes. Iron oxides are one of the main minerals in paddy soils, ...
