Soil CO2 flux in a Japanese cool-temperate grassland

The 9th U.S.-Japan Workshop on Global Change, Carbon Cycle Management in Terrestrial Ecosystems

There have been very few studies on soil CO2 flux, i.e. soil respiration, in Japanese grasslands, because abundant precipitation (more than 1000 mm) limits establishment of natural grasslands.  Semi-natural (managed) grasslands, however, can be maintained by mowing and burning in Japan.  Since 1998,
