“…This is consistent with many of the reported studies on soil respiration in different land-use systems (Houghton 1999) and is consistent with current knowledge that under agricultural cultivation, soil C can be lost very quickly (Monreal and Janzen 1993). However, higher soil respiration rates in forested sites than in cropland have also been reported (Larionova et al 1998). Soil respiration rates can be controlled by many different factors, such as disturbance (Joshi et al 1991;VandenBygaart et al 2003), plant species composition (Joshi et al 1991;Salimon et al 2004), climatic conditions (Schimel et al 1994;Yuste et al 2003), root respiration (Bond-Lamberty et al 2004), and management input (VandenBygaart et al 2003;Merino et al 2004).…”

. 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...

“…Gas-tight chambers (19.5 cm high, 29.5 cm diameter) were fixed on the frames. Measurements were taken between 10 and 12 h, because soil respiration at this time of the day can be used to estimate the mean daily rate of respiration [20].

Initial mineralization of organic matter in a forest plantation soil following different logging residue management techniques

-The influence of tree harvesting and site preparation on inorganic N, net N mineralization and nitrification, microbial biomass and emission of CO 2 from soil were evaluated in a field experiment. The study was carried out in a plantation of Pinus radiata D. Three different site preparation techniques were used: a) whole tree harvesting with removal of logging residues and forest floor, b) mechanical incorporation of logging residues and forest floor into the upper 20 cm of the mineral soil, and c) logging residues left on-site. The incorporation of residues into the mineral horizon favoured N immobilization. This effect was accompanied by a higher metabolic activity, as indicated by the higher microbial biomass and CO 2 emissions, as well as the higher N contents in decomposing logging residues. In the plot with residues left on site, no changes in soil microbial biomass were observed, although there was a high degree of N immobilization.forest soils / soil organic matter / Pinus radiata / microbial biomass / carbon / nitrogen / mineralization / nitrate / ammonium Résumé -Minéralisation de la matière organique dans le sol d'un peuplement forestier après différentes méthodes de gestion des résidus d'exploitation forestière. L'influence des défrichements et de la préparation du terrain sur l'azote inorganique, la minéralisa-tion et la nitrification nette de l'azote (N), la biomasse microbienne ainsi que sur l'émission du CO 2 degagé du sol, a été evaluée par une expérience sur le terrain. L'étude a été menée pendant 12 mois dans des peuplements de Pinus radiata D. Don sur un sol infertile, acide et sableux dans une zone humide et tempérée du Nord-Ouest de l'Espagne. Trois méthodes différentes de préparation du terrain ont été utilisées : a) exploitation totale des résidus forestiers, b) incorporation mécanique des résidus sur une épaisseur de sol de 15 cm, c) abandon des résidus d'exploitation à la surface du sol. L'incorporation des résidus dans l'horizon minéral a favorisé l'immobilisation de N. Cet effet a été accompagné d'une part, par une activité métabolique supérieure, indiquée par une biomasse microbienne élevée et des émis-sions de CO 2 croissantes, et d'autre part, par des contenus de N élevés dans la décomposition des déchets du bois. Par contre, dans la parcelle où l'on avait abandonné les résidus en surface il n'y a pas eu de changements dans la biomasse microbienne, même s'il y a eu une forte inmobilisation de l'azote (N). L'enlèvement des résidus d'exploitation a à peine eu une influence sur le minéralisation. sols forestiers / matière organique du sol / Pinus radiata / biomasse microbienne / carbone / azote / minéralisation / nitrate / ammonium Ann.

“…Mean annual CO 2 emission of cereal fields was estimated to range from 0.75 (DC) to 1.14 (SC) Mg C ha -1 . This estimated value is the same level as that for the Canadian prairie (de Jong 1974), while it was lower than for Eurasian Chernozem 8,18 . Mean annual CO 2 emission of fallow and meadow fields was estimated to range from 0.71 (DC) to 0.92 (SC) Mg C ha -1 and from 0.61 (DC) to 1.34 (OC) Mg C ha…”

Farm-regional evaluation of soil organic carbon (SOC) dynamics for the chernozem zone in northern Kazakhstan is now vitally important for making agro-environmental policy. In this study, the author intends to evaluate spatial and temporal variation of the SOC budget and to seek alternative ways of sustainable land use in northern Kazakhstan. To achieve this final goal, this study established the following objectives: to (1) clarify the spatial patterns of soil organic matter content, (2) clarify the influence of land use on the dynamics of soil organic carbon in situ for the three differential soil classes, and (3) clarify spatial and temporal variability of SOC budget in farm-regional scale. The highest SOC content was found in the northern region and the lowest content in the southern region of the study area. Potentially mineralizable carbon (PMC) content, however, was highest in the midwestern region. Furthermore, fluctuations in CO 2 emission from the soils showed a similar pattern to temperature fluctuations. Using PMC, soil temperature, precipitation and/or dryness factor, 40-80% of the variation of CO 2 emission could be estimated. From farm-regional evaluation, it is concluded that the spatial and temporal variation of the SOC budget was significantly affected by the crop rotation system in the area. In addition, the fallow-and barley-based crop rotation systems accelerate SOC depletion in the study area.
