Soil respiration during secondary succession: Influence of temperature and moisture

Soil respiration and FDA hydrolysis following conversion of abandoned agricultural lands to natural vegetation in Central Korea

“…Mean annual soil respirations (g CO2 m -2 hr -~) were 0.28 _+ 0.02 for RF, 0.36 ___ 0.03 for CS, and 0.29 _+ 0.02 for IF (Table 1). These values were slightly lower than those measured previously in this same study area (Son et al, 2003), perhaps due to interannual variations (Mathes and Schriefer, 1985;Schlentner and van Cleve, 1985;Lavigne et al, 2004). Mean soil respiration was significantly different among sites, and there was a significant month x site interaction.…”

Measurement of soil respiration in the field: influence of temperature, moisture level, and application of sewage sludge compost and agro-chemicals

“…Both curves assumed a similar shape with a peak in summer, indicating that the soil respiration is affected by the temperature . (MATHES and SCHRIEFER 1985), 16 in a shifting cultivation area (Thailand) (TULAPHITAK et al 1985), and 10 in a warm-temperate evergreen broadleaf forest (Japan) (KIRITA 1971). It was also shown in these reports that soil respiration was markedly affected by the temperature.…”

“…This method is ditTerent from the "air flow method," in which the use of IRGA is almost standardized (i.e. EDWARDS and SOLLINS 1973;MATHES and SCHRIEFER 1985), and does not require many valves and long tubes for the measurement of a large number of sample plots. Accordingly, an in situ measurement is relatively easy, but more manual work is required.…”

Effects of CO2concentration in rhizosphere on nodulation and N2fixation of soybean and cowpea

“…The CO 2 concentration in soil is affected by the water content, soil temperature (Bouma et al 1997;Mathes and Schriefer 1985) and soil types (Howard and Howard 1993). Buyanovsky and Wagner (1983) reported that the CO 2 concentration in soil plowed for planting ranged from 5 to 10 dm' m-' at the 20 cm depth under optimum soil water content conditions and increased until 70 dm 3 m-' depending on the plant growth.…”
