Influences of snow cover and soil-frost on ground surface flux and soil gas concentration of CO2 in an agricultural land in northern Japan
2011
Journal of Agricultural Meteorology
Our main objective was to elucidate how snow cover and soil frost influenced CO2 dynamics over agricultural land. We observed the CO2 flux above the soil or snow surface continuously using the commonly used static-chamber method and the CO2 concentration in the soil on snow-removal plot and untreated control plot over agricultural land in northern Japan from September 25, 2009, to May 31, 2010. The recorded largest CO2 flux was 3.9 µmol m -2 s -1 and CO2 concentration in soil was 390-5000 ppm.
