  • Soils in an environmental context: an American perspective
  • Agropedology ; Ecosystem ; Environment ; Environmental management ; Global change ; Groundwater ; Landscape ; Nitrate ; Pesticide ; Pollution ; Soil ; Soil erosion ; Soil properties ; Soil science ; Water quality
  • The understanding of fundamental properties of and processes in soils has both agricultural and environmental benefits. On a global basis, soil science will continue to be viewed as primarily an applied agricultural science. Soil science also plays
  • a key role in understanding and modeling the transport of pollutants to ground water and to remediation of polluted urban environments. The AA. provide a few examples of how soil science has contributed to solutions of environmental problems

  • Apparent thermal diffusivity in soil: estimation from thermal records and suggestions for numerical modeling
  • Geophysics ; Methodology ; Model ; Soil ; Soil properties ; Soil temperature ; Sweden ; Temperature
  • The concept of apparent thermal diffusivity in soil is discussed and defined as consisting of an intrinsic and a pseudo part. A method that uses a numerical model of heat conduction and measured soil temperatures to estimate apparent thermal

  • Arctic Region ; Cold area ; Gley ; Grain size distribution ; Microrelief ; Patterned ground ; Plant canopy ; Soil ; Soil properties ; Solifluction ; Spitsbergen ; Svalbard
  • The following patterning of the ground surface was observed in the Bellsund region: sorted circles, mud boils, cell forms, solifluction (striped) forms and large polygons (tundra polygons). The soils associated with these forms often have different

  • Comparison and contrast of processes of soil formation in the San Timoteo badlands with chronosequences in California
  • California ; Chronosequence ; Fault ; Geochronology ; Pedogenesis ; Pleistocene ; Pliocene ; Soil ; Soil properties ; United States of America
  • The purpose of this study is to develop a soil chronology that allows a rigorous correlation of geomorphic surfaces within the San Timoteo Badlands (STB), as well as to nearby surfaces with determined ages at Cajon Pass, Merced, and Anza, to further

  • Active layer ; Alaska ; Periglacial features ; Permafrost ; Soil temperature ; Soil water ; Time series
  • This paper documents the relative magnitude of thermally induced sorption/desorption effects in a soil where all three phases of water coexist. Soil temperature and electric potential time series are used to monitor temperature-driven variations
  • in relative soil-water solute concentration during a large portion of the year.

  • Estimating stone and boulder content in forest soils - evaluating the potential of surface penetration methods
  • Forest ; Methodology ; Moraine ; Roughness ; Soil ; Soil properties ; Surface deposits ; Sweden
  • This study aims a) to investigate the stoniness (relative volume of stones and boulders) of representative forest soils in central Sweden, b) to evaluate the possibilities to predict soil stoniness with non-destructive surface penetration methods
  • , particularly the rod penetration method suggested by Viro in 1952. The general evaluation of surface penetration methods revealed that large errors in very stony soils cannot be avoided. It is inherent in the method and not caused by sampling. This conclusion

  • 137Cs losses from a loamy surface water gleyed soil (inceptisol); a laboratory simulation experiment
  • Experimentation ; Geochemistry ; Isotope ; Loam ; Porosity ; Rainfall simulation ; Rill wash ; Slope gradient ; Soil ; Soil erosion ; Soil properties ; Suspended load
  • The series of experiments have confirmed that 137Cs is rapidly fixed to soils and eroded sediments, but also demonstrate that patterns of uptake are not uniform and are, therefore, difficult to predict. Some evidence has been obtained to suggest
  • that preferential 137Cs transport occurs during and immediately following its delivery to the soil, which could result in a bias in 137Cs distribution and, hence, increase the bias associated with estimating soil erosion and sediment delivery rates from 137Cs
