Therefore, the Solonchaks are glcyic, hyposaline or hypcrsaline and generally sulfatic. High levels of water saturation and sulfidic material are prominent features of the floodplain soils.
The presence of Gleyic Hypersalic Solonchaks or Flyposalic Solonchaks (Sulfatic) in the floodplain, Haplic Gleysols (Thionic) in the low terrace and Endogleyic Arenosols in the middle terrace substantiates the importance of gleyic processes for all landscape positions.
Soil distribution is established according to the following pattern: Gleyic Hyposalic and Hypersalic Solonchaks (sulfatic) in the floodplain, Haplic Gleysols (thionic) in the low terrace and Endogleyic Arenosols in the middle terrace.
