metadata.value: Humid conditions do not encourage the formation of salt-affected soils due to leaching salts
  out of soil profiles. Nevertheless, the occurrence of salt-affected soils in a humid climate is evident
  as a result of other factors excluding the climate. Soil salinity in these landscapes is caused
  by anthropogenic salinization. The objective of this study was to identify types of chemical
  composition and salinity level of soils forming within the impact zone of artesian water discharge.
  We also determined the degree of contrast to adjacent non-saline soils and salt contamination
  boundaries. Soil and water samples were collected from three sites located in the
  Yaroslavl’ region, the Upper Volga. Sampling was done in June 2017. In the Upper Volga region
  high-mineralized water rises from saline aquifers via abandoned exploration wells drilled
  in the 1960s. These soils are found under an average annual rainfall of about 500–700 mm in
  the taiga zone. This type of climate and vegetation cover normally should lead to the formation
  of Albic Retisols. Saline waters affecting soils are dominantly Na-Cl or Ca-Na-Cl-SO4 brines.
  Total dissolved solids in the saline waters range from 10000 to 259500 mg·L–1. Salt-affected
  soils have from low to high salinity (0.1–0.8 %) but salt content does not exceed 1 %. In the
  study areas, maximum salinity in the investigated soils was fixed near the water table or was associated with lithic discontinuity or abrupt textural change. Salt leaching from the upper horizons
  prevails in the course of the annual cycle and that is what differs these soils from hydromorphic
  saline soils formed in arid climates. Field electrical surveys of salinity indicated the
  local zones of salinization. The salinization phenomenon in humid climates is not part of the
  main pedogenic processes, but an additional process. The upper horizons of salt-affected soils
  tend to have similar morphological features to zonal and intrazonal soils. The salt-affected
  soils studied were classified according to WRB as Orthofluvic Fluvisol (Humic, Loamic, Endosalic,
  Technic), Orthofluvic Gleyic Fluvisol (Humic, Siltic, Endosalic, Raptic), Amphistagnic
  Albic Retisol (Siltic, Anoaric, Cutanic, Endosalic) and Albic Retisol (Siltic, Anoaric, Cutanic,
  Endosalic, Raptic).
