- This paper examines frozen fine-grained soils, mainly of Pleistocene and Holocene age, that are distributed along the Arctic coast at the surface and which contain soluble salts. Salinization is determined by both the conditions at formation
- with an increase in ice content. An important feature of the saline soils of the Russian Arctic coast is their heterogeneity.
- , and subsequent processes at cryogenic temperatures. An increase in salinization with depth is observed. This is most likely caused by moving of salts from the upper permafrost layers as the result of the migration of pore water. Salinization in general increases

- In Chongmind Island, eastern China, the AA. explored the way vegetation restoration affected the profile distributions of soil moisture and salinity in various seasons in naturally salt-affected coastal saline land. In four types of vegetation, five
- soil cores were acquired in the 80 cm depth range. Salt profiles showed the higher values in surface soil in control plots, whereas the pattern of soil salinity showed the reverse trend under vegetation. The effect of vegetation restoration
- on the profile distributions of salt is significant. In control plots, soil moisture and salinity showed a clear seasonal trend. Relative to control plots, the seasonal trend of soil moisture and salinity under vegetation appeared to be complex for no clear trend
- was observed. It can be concluded that plant communities significantly affect the spatial–temporal distribution of soil salinity. The selection of plant species is important in the reclamation of costal saline land.

- Domaine aride ; Géographie physique ; Israël ; Sol ; Sol salin
- All soils in the desertic regions of Israel, south of the 220 mm precipitation isohyet, are saline and gypsiferous. There is a good correlation betweeen salt distribution and the stability and age of the pedomorphic surfaces, which supports
- the conclusion that the major sources of the salts are airborne ones blown in over a long period of time. Detailed salt profile data of six characteristic stable soils of the desert and desert fringe areas indicate that salinity increases with aridity. Depth

- excess salinity on soil microbes.
- . The results suggest that agroforestery under saline irrigation should favour salt tolerant species preferring ammonium-N to nitrate-N as a N source. Ammonium production was unaffected by salinity levels suggesting that oorganic mulch incorporation may buffer

- and species abundance) and soil (moisture, pH, redox potential, electrical conductivity and soluble ions). Multivariate analysis showed that vegetation was closely related to soil moisture and salinity. The soils colonised by steppe grasses and halophilus
- and halonitrophilus shrubs were the driest and least saline. The results support the role of vegetation as bioindicator of disturbances and the use of soil–plant relationships models to improve the environmental management of saline ecosystems.
- The main aim was to establish a conceptual model in order to use vegetation as bioindicator of soil conditions. With this model, environmental changes – based on the observation of vegetation – could be detectable, allowing the prevention

- This study presents easy procedures for comparing soil salinity profiles, which were used to assess 4 saline wetlands in the Central Ebro Basin, NE Spain. Soil salinity measurements at sites where different halophytes were dominant were recorded
- in 3 seasons (spring–summer–winter) throughout the year in 1979–1980 and 1999–2000, with additional measurements in 1985. Electrical conductivity of saturation extracts (ECe) and the concentrations of major ions were measured in 400 soil samples for 5
- halophytes. The 5 halophytes are ranked both by the salinity and the sodicity of their habitats. This work is a baseline to detect to natural or anthropic salinity changes.
