  • that abstraction can be affirmed as a necessary element of understandings of livedworlds in the making. Doing this requires revisiting the relation between abstraction and two matters ofdisciplinary concern: experience and materiality. These matters of concern

  • Vegetation influence on organic matter source of black soils from high altitude rocky complexes traced by 13C and 15N isotopic techniques
  • composition of bulk soil and humic acid (HA). The majority of sites in the HARC presented a soil organic matter originated from C3-vegetation and demonstrated an intense N cycling based on the δ15N data. Even though charcoal could be suggested as a component
  • of soil genesis for most of the HARC sites, the raised data was not consistent to consider fire a key process for soil organic matter existence in these areas.

  • Charcoal and stable soil organic matter as indicators of fire frequency, climate and past vegetation in volcanic soils of Mt. Etna, Sicily
  • . The distribution into labile and stable organic fractions provided insight into the stabilisation and turnover mechanisms of soil organic matter (SOM). The results suggest that a high fire frequency is a powerful rejuvenating factor for soil organic matter

  • Holocenic proxies of sedimentary organic matter and the evolution of Lake Arari-Amazon Region
  • . The integration of data on sedimentary structures, pollen, carbon and nitrogen isotope records, C/N ratios and radiocarbon ages allowed the identification of changes in vegetation and the sources of organic matter accumulated in the lake during the Holocene

  • This study examined the changes in soil properties and soil quality 30 years after cultivated farmland was restored back to forest land in Loess Plateau, China. Specifically, organic matter, total nitrogen (N) and phosphorus (P), available N, P
  • in the soil of mixed forest of Chinese pine and amorpha decreased. The study also found that the organic matter content was relatively low in the restored soils, compared with not-restored land. This may be caused by the high enzyme activity per unit
  • of organic carbon in the soils of the study area which tends to help decompose and therefore decrease the organic matter in soil.

  • Erosion of organic matter from sandy soils : Solving the mass balance
  • This study aimed to investigate the erosion of organic matter (OM) from rapid-crusting, sandy soils. Soils from both organically and conventionally farmed land from Shropshire, UK, were exposed to simulated rainfalls differing in both intensity

  • Variations in suspended and dissolved matter fluxes from glacial and non-glacial catchments during a melt season at Urumqi River, eastern Tianshan, central Asia
  • The effects of climatic conditions on the delivery patterns of suspended solid and dissolved matter are evaluated by examining their correlation with air temperature, precipitation and runoff from glacial and non-glacial catchments at the headwaters
