Soil organic matter formation along a chronosequence in the Morteratsch proglacial area (Upper Engadine, Switzerland)

Clay fractions from a soil chronosequence after glacier retreat reveal the initial evolution of organo–mineral associations

“…Significant amounts of proteinaceous materials in the residual fraction after H 2 O 2 treatment were also detected by Cheshire et al (2000) and Egli et al (2010). We found 22-32% of the total nitrogen in this fraction, but only 6-8% of the total OC.…”

Between ice and ocean; soil development along an age chronosequence formed by the retreating Breiðamerkurjökull glacier, SE-Iceland

“…This area was estimated by Arnalds (2010) to have a high deposition rate of 75-250 g m −2 yr −1 depending on topography and wind pattern. reported that the successional stages in the Skaftafellsjökull proglacial area also differ from what has been reported for other pro-glacial areas such as the Alps, Alaska and China, where forests are established within 70-150 yrs (Crocker and Dickson, 1957;Egli et al, 2010;He and Tang, 2008). In front of Skaftafellsjökull, there seemed to be a lag time in the initial plant establishment and soil development, possibly delaying the development of woodlands.…”

Recent applications of vibrational mid-Infrared (IR) spectroscopy for studying soil components: a review

“…In another approach, a relative peak area has been used to study longer-term changes in HAs from soils under bare fallow over 36 years (Tatzber, et al, 2009), and also in bulk soils from a 140-year proglacial chronosequence (Egli, et al, 2010), which reflected changes in SOM quality as measured by independent methods. Demyan, et al (2012), used the peak areas at 2930, 1620, 1530 and 1159 cm -1 selected in the typical range of organic functional groups.…”
