In this paper we briefly introduce our results
of soil CO2 concentrations in an arable field in the campus of
NIAES, a grass field and a pine forest in central mountaneous area in Japan. The soil CO2 concentrations
seasonally variated with soil temperature changes at all the three sites. Temporal variations in CO2
concentrations in the arable and the grass field were more linked to changes in
soil moisture than those in the forest. Soil CO2 concentrations were
generally largest in the grass field. CO2 concentrations at the
grass field and pine forest under snow cover showed positive relationship with
snow depth.
