“…The variation in SOC projections among the different climate models over NSW in this study appears to be mainly attributable to the wide variations in projected regional rainfall change, as against the more uniformly increasing regional temperatures, a situation also reported by Falloon et al (2007) in their global study.…”

Digital soil mapping (DsM) techniques combined with space-for-time substitution (sFTs) processes were used to map and examine soil organic carbon (sOC) changes caused by projected climate change over New south Wales, Australia until ~2070. Twelve projections were derived from four global climate models downscaled with three regional climate models. A marked variation in the direction and magnitude of sOC change was demonstrated with the different projections. Mean state-wide predictions (0-30 cm depth) ranged between 2.9 Mg ha -1 gain and 8.7 Mg ha -1 sOC loss. Greater consistency among climate change projections is required before we can confidently predict sOC changes. By using averaged results from the 12 projections, broad trends were revealed for the change in sOC over two intervals (0-30 and 30-100 cm). A mean loss rate of 2.0 Mg ha -1 for the upper interval was demonstrated and a total loss of 737 Tg of CO 2 equivalent for the entire depth to 100 cm but the 95% confidence interval was wide. Although changes are primarily controlled by the balance between changing temperatures and rainfall, the extent of change also depends on the environmental regime, with differing changes demonstrated over 36 current climate-parent material-land use combinations (e.g., projected mean sOC decline is <1 Mg ha -1 for dryhighly siliceous-cropping but >15 Mg ha -1 for wet-mafic-native vegetation C limate change will impact on many aspects of the global environment and civilization generally, with changes in our soil resources being one important yet not widely understood consequence. Changes in key soil properties such as SOC content will influence agricultural productivity and our ability to feed and support the growing world population. Native ecosystems will be impacted, with modifications to species distribution and abundance at local, regional, and national scales. Changes in the potential of soils to sequester C or release it to the atmosphere are crucial for climate change modeling and mitigation strategies (Lal et al., 2007;Baldock et al., 2012).Although there has been widespread work on the relationship of climate to soils, dating back to the pioneering work of Dokuchaev in 1899 (Dokuchaev, 1967 transliteration) andJenny (1941) Core Ideas• Potential changes in soil organic C to 2070 mapped (100-m grid) and examined.• The direction and magnitude of change varied between the 12 climate projections.• Differing changes revealed for 36 current climate-parent material-land use regimes.• Digital soil mapping-space-for-time substitution is useful for climate change study

“…O potencial de fixação e estocagem de C no solo sofre influência das condições climáticas locais, do relevo, da drenagem e do tipo de manejo de solo adotado, entre outras variáveis que ditam as taxas de aumento do C orgânico do solo (Lal, 2005;Falloon et al, 2007;Smith, 2008). Fonseca (1984), ao estudar o comportamento das propriedades químicas de um Latossolo Vermelho-Amarelo distrófico, sob mata de eucalipto e natural, constatou que o C orgânico do solo variou com o tipo de cobertura vegetal e decresceu exponencialmente com a profundidade do perfil do solo.…”

“…The dynamic equilibrium between these two large pools of C is mediated by the biosphere and expected to adjust to global change with the result of a net transfer of C from soils to the atmosphere (Jones et al, 2005;Falloon et al, 2007). For predicting these dynamics, it is necessary to gain information on the turnover rates, or stability, of different soil organic C pools (Zimmermann et al, 2007).…”

Abstract. Life on earth drives a continuous exchange of carbon between soils and the atmosphere. Some forms of soil carbon, or organic matter, are more stable and have a longer residence time in soil than others. Relative differences in stability have often been derived from shifts in δ 13 C (which is bound to a vegetation change from C3 to C4 type) or through 14 C-dating (which is bound to small sample numbers because of high measurement costs). Here, we propose a new concept based on the increase in δ 15 N and the decrease in C:N ratio with increasing stability. We tested the concept on grasslands at different elevations in the Swiss Alps. Depending on elevation and soil depth, it predicted mineral-associated organic carbon to be 3 to 73 times more stable than particulate organic carbon. Analysis of 14 C-ages generally endorsed these predictions.
