“…A small portion (2%) of the CO 2 was produced below a depth of 175 mm, 8% was produced in the 50-to 175-mm soil layer, and 90% was produced in the 0-to 50-mm soil layer. Nakadai et al (2002) reported that 70% of CO 2 was produced in the 0-to 100-mm soil layer in a bare field in Japan. The reason that Nakadai et al (2002) had lower CO 2 production in the 0-to 100-mm soil layer might be that their field was maintained bare for a longer time (>20 yr) than this bare field (2 yr), and another potential reason might be the difference in the soil texture at the two locations.…”

The low percentage of production in deep layers in this work may be attributed to the unfavorable wet conditions and lower temperature in deeper soil layers.…”

“…Numerous studies have reported increases (either linear or exponential) in soil respiration with rising soil temperature (Kirschbaum 1996;Fang and Montcrieff 2001;Nakadai et al 2002). Conant et al (2004) concluded that soil respiration responses to changes in temperature are a function of direct impacts to microbial activities.…”

. 2006. Some characteristics of soil respiration in hybrid poplar plantations in northern Alberta. Can. J. Soil Sci. 86: 257-268. Fast-growing hybrid poplars are being planted in the Canadian prairies to meet the increasing demand for fibre and environmental services of trees and forests; however, the impact of hybrid poplars on C dynamics and storage on previously farmed land is largely unknown for the boreal region. We measured soil CO 2 efflux along a chronosequence (3-, 9-, and 11-yr-old stands) of hybrid poplar (Populus deltoides × Populus × petrowskyana var. Walker) plantations and a control agricultural field from June to August 2004. Measurements were made between 0800 and 1800 with a portable Li-Cor 6400-09 system and were based on 4-5 min averaging. We also measured the response to simulated rainfall and the diurnal fluctuation of soil CO 2 efflux. Soil CO 2 efflux ranged from 1.30 µmol CO 2 m -2 s -1 in the 3-yr-old plantation to 5.41 µmol CO 2 m -2 s -1 in the agricultural control field, or from 0.17 µmol CO 2 m -2 s -1 kg -1 C (based on soil organic C content to a 0.4 m depth) in the 3-yr-old plantation to 1.09 µmol CO 2 m -2 s -1 kg -1 C in the 11-yr-old plantation. Simulated rainfall applied in the 3-yr-old plantation and a newly planted site resulted in an immediate pulse of CO 2 efflux, 2.90 and 2.54 µmol CO 2 m -2 s -1 , respectively, followed by an efflux rate sustained slightly above pre-irrigation levels. No secondary pulse of soil respiration was observed in the 2-h period following water application. Diurnal variation of soil respiration was found to be small between 0600 and 1900 in the agricultural control field, with values that varied from 2.66 to 3.17 µmol CO 2 m -2 s -1 . Continued monitoring of soil respiration and other C cycling processes in the chronosequence will improve our understanding of the potential for C sequestration in hybrid poplar plantations in northern Alberta. Les auteurs ont aussi mesuré la réaction à une pluie artificielle et la fluctuation diurne des efflux de CO 2 du sol. Ces derniers varient de 1,30 µmol de CO 2 par m 2 et par seconde pour la plantation de trois ans à 5,41 µmol pour la culture témoin, ou de 0,17 µmol de CO 2 par m 2 et par seconde, par kilo de C (teneur du sol en C organique à 0,4 m de profondeur), pour la plantation de trois ans à 1,09 µmol pour celle de onze ans. La pluie artificielle a immédiatement entraîné un efflux de CO 2 de 2,90 et de 2,54 µmol par m 2 et par seconde dans la plantation de trois ans et dans une nouvelle plantation, respectivement. Cette réaction a été suivie par un efflux stable, légèrement supérieur à celui observé avant l'irrigation. Aucun signe de respiration secondaire du sol n'a été observé au cours des deux heures qui ont suivi l'arrosage. La respiration du sol varie peu durant le jour, entre 6 h et 19 h, dans le champ cultivé, les valeurs fluctuant de 2,66 à 3,17 µmol de CO 2 par m 2 et par seconde. En poursuivant l'étude de la respiration du sol et d'autres processus du cycle du carbone dans cette chronoséquence...

“…Chu et al (2007) reported values of 0.427-0.524 g CO 2 -C m -2 d -1 CO 2 efflux from an Andisol upland field in Japan under different types of fertilizer management using a closed chamber method that was the same as that used in the present study. Similarly, Nakadai et al (2002) conducted a field experiment using a chamber method and reported that the average soil CO 2 efflux from an Andisol under the tillage treatment was in the range of 0.73-1.39 g CO 2 -C m -2 d -1 according to the season. However, the values of CO 2 efflux from Andisol determined from bottle incubation were significantly overestimated (Dumale et al, 2009;Nakadai et al, 2002), because the gas status and soil structure in bottle incubation were significantly different from those in the field experiment.…”

Accurate measurements of CO2 efflux from soils are essential to understand dynamic changes in soil carbon storage. Column incubation experiments are commonly used to study soil water and solute transport; however, the use of column incubation experiments to study soil CO2 efflux has seldom been reported. In this study, a 150-day greenhouse experiment with two treatments (no-tillage and tillage soils) was conducted to evaluate the applicability of soil column incubation experiments to study CO2 efflux. Both the chamber measurement and the gradient method were used, and results from the two methods were consistent: tillage increased soil cumulative CO2 efflux during the incubation period. Compared with fieldwork, incubation experiments can create or precisely control experimental conditions and thus have advantages for investigating the influence of climate factors or human activities on CO2 efflux. They are superior to bottle incubation because soil column experiments maintain a soil structure that is almost the same as that in the field, and thus can facilitate analyses on CO2 behaviour in the soil profile and more accurate evaluations of CO2 efflux. Although some improvements are still required for column incubation experiments, wider application of this method to study soil CO2 behaviour is expected.
