“…Sorokin et al (2006) reported slow decomposition of soil organic matter (SOM) in hydromorphic soil because of a low coefficient of microbiological mineralization and the lack of nitrogen (coefficient of oligotrophy). When hydromorphic conditions occur, because of saltwater intrusion by subsidence phenomena, a saline-sodic condition may be established.…”

“…Minimum SOC C was 0.1 g C kg −1 in South Africa (Olaleye et al, 2014) and a maximum of 540 g C kg −1 was observed in Germany's Black Forest, located in humid temperate climate (Fiedler et al, 2002). The lowest Fe and Al contents of close to 0% were found in Russian (Sorokin et al, 2006). The highest soil Fe content was 17% found in Italy (Ferronato et al, 2016), while the highest Al content of 38% was reported in Brazil by Fritsch et al (2009).…”

“…MAP ranged from minimum 127 mm year −1 in USA (Thompson et al, 2007) to maximum 3833 mm year −1 in a Bolivian tropical forest (Schawe et al, 2007), with an average of 1316 mm year −1 . MAT varied from minimum −1.6°C year −1 in temperate Russia (Sorokin et al, 2006) to 30.15°C in tropical Brazil (Schiavo et al, 2012). Soil pH was very acidic with a value of 2.5 in an alluvial wetland in Italy (Ferronato et al, 2016), while the other extreme was the basic soil with a pH value of 8.9 in a floodplain of a tropical forest in Brazil (Guimaraes et al, 2013).…”

Soil hydromorphy and soil carbon: A global data analysis

et al. 2018

Wetland soils are an important component of the Global Carbon Cycle because they store about 20-25% of the terrestrial soil organic carbon (SOC). Wetlands occupy about 6% of the global land surface and any change in their use or management has potentially dramatic consequences on greenhouse gases emissions. However, the capacity of wetland soils to store carbon (C) differs from place to place due to reasons still not well understood. The objective of this review was to evaluate the global variations in wetlands SOC content (SOC C) and to relate it to key soil and environmental factors such as soil texture, intensity of soil hydromorphy, metallic element content and climate. A comprehensive data analysis was performed using 122 soil profiles from 29 studies performed under temperate, humid, sub-humid, tropical and sub-arctic conditions. The results point to average SOC C of 53.5 ± 15.8 g C kg −1 with a maximum of 540 g C kg −1. SOC C increased with increase in intensity of soil hydromorphy (r = −0.52), Al (r = 0.19) and Fe content (r = 0.21), and decreased with soil pH (r = −0.24). There was also a surprising tendency for intensity of soil hydromorphy, and thus SOC C , to decrease with increasing mean annual precipitation and soil clay content. These results contribute to a better understanding of the impact of soil hydromorphy in wetlands on organic C stabilization in the soils. However, further studies with additional information on soil bulk density to assess carbon C stocks, still need to be performed.
