In the concrete jungle at the core of a city, carbon dioxide (CO2) emissions are dominated by the fossil fuels burned by the dense concentrations of cars and buildings. Boston University researchers now have shown, however, ...

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, ...

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 ...
