  • The study area was located in Cehegin in the northwest of the province of Murcia at an altitude that ranges from 600 to 800 m.a.s.l. The results of an experiment to evaluate the effect of rainfall characteristics on organic carbon (OC) losses
  • and on the type of particles mobilised by erosion under natural rainfall and under different land uses (non-disturbed forested area, and a non-irrigated olive cropland) at plot scale are presented. Labile (particulate organic carbon, POC) and stable (mineral
  • associated organic carbon, MOC) carbon pools were measured in soil and sediments. OC in soil aggregates explained the effect of rainfall on carbon mobilisation. The results showed that OC enrichment ratios were higher in olive than in forest in events of low
  • Carbon storage and greenhouse gases emission from a fluvial reservoir in an agricultural landscape

  • The significance of organic carbon (C) burial in fluvial reservoirs on the global C cycle and atmosphere composition remains debatable. Over a 4-year period (2005–2008), dissolved concentrations and fluxes of carbon dioxide (CO2), methane (CH4
  • Patterns of soil organic carbon and nitrogen in relation to soil movement under different land uses in mountain fields (South Central Pyrenees)

  • was done in different parts of the slope to assess the pattern distribution of soil organic carbon (SOC) and nitrogen (SON). Other general soil properties analysed : pH, EC, carbonate content, grain size distribution and additional information derived from
  • . Under the land use practices in the studied fields the bottom slope positions accumulate soil particles and act as sinks of soil carbon and nitrogen in these mountain agricultural landscapes.
  • Variability of relationships between soil organic carbon and some soil properties in Mediterranean rangelands under different climatic conditions (South of Spain)
