“…There were no significant differences in parameter values in EC, SC, Na + , and CO 3 2´b etween these two years. Because of high CV values for these parameters (CV > 1), soil salinity-sodicity in different ground elevation may be different under microtopography [10,15]. To further evaluate the impact of ground elevation gradient on these soil salinity-sodicity parameters (EC, SC, Na + , and CO 3 2´)…”

“…The higher the evaporation, the faster the moisture is supplied, and the more the salt is accumulated. Low rainfall and high evaporation can increase the salt contents at the surface soil, especially at the upper part and middle part of microtopography [15]. The microtopography could influence the pattern and magnitude of spatial variability in salinity and alkalinity [36].…”

“…The scholars have noticed the heterogeneous distribution of soil salinity-sodicity under microtopography and carried out a lot of studies, such as soil moisture transform and distribution characteristics of soil salt under microtopography [10,15] and analysis of spatial variation of soil salinity-sodicity [16][17][18]. It is shown that the spatial variation of soil salinity is mainly affected by the environmental factors (the topography, hydrological process and climate conditions).…”

Abstract:Over three million hectares of salt-affected soils characterized with high salinity and sodicity caused serious land degradation in Songnen Plain, northeast China. Soil salinity-sodicity heterogeneous distribution under microtopography is usually influenced by several environmental factors. The side direction movement of soil water driven by water from depression is the key factor that aggravates the soil salinization under microtopography in dry condition. In this study, the differences in surface soil salinity-sodicity (0-10 cm) between dry year and wet year were compared, and the relationship between soil salinity-sodicity and environment factors such as ground elevation, surface ponding time, surface ponding depth, and soil moisture at four soil layers (0-10, 10-30, 30-60, and 60-100 cm) were analyzed using redundancy analysis (RDA) and simple correlation analysis (Pearson analysis) for two different hydrological years. Analyzed soil salinity-sodicity parameters include soluble ions (Na + , K + , Ca 2+ , Mg 2+ , CO 3 2´, HCO 3´, Cl´and SO 4 2´) , salt content (SC), electrical conductivity (EC), sodium adsorption ratio (SAR), and pH. Results showed that values of SAR, Cl´, and SO 4 2´w ere significantly higher in dry year than in wet year, while Ca 2+ , Mg 2+ , K + , and HCO 3´s howed the opposite results. Values of Na + , CO 3 2´, and EC were significantly higher at higher ground elevation gradient (20-40 cm) in dry year than wet year. Redundancy analysis indicated that spatial distributions and variations of salinity and sodicity in surface soil layer were related with environmental factors of ponding depth, ponding time and ground elevation in wet year, and they were related with ground elevation, ponding depth, ponding time, and soil moisture at 30-60 and 60-100 cm soil layer in dry year. Ponding depth and ground elevation rank first and second as the influential factors of the spatial distribution and variation of soil salinity-sodicity in wet year. However in dry year, primary and secondary influential factors are ground elevation and soil moisture at 60-100 cm soil layer.

“…However, Joeckel and Clement (2005) showed that repeated 484 wetting and drying cycles caused illitization in modern saline-sodic wetland soils, resulting in 485 illite dominating the basin surface of the soil, with smectite becoming dominant at depth. In 486 the gleyed Inceptisols with brecciated tops, the uppermost 10 cm are dominated by illite (and 487 more illitic I/S) and the lower parts are dominated by more smectitic I/S suggesting that 488 illitization may have occurred here in the Ballagan Formation palaeosols (Fig.…”

“…Large lakes were absent on the Platte rivers in historic times (cf., Joeckel and Ang Clement, 2005;Joeckel and Henebry, 2008;Horn et al, 2012). The Holocene channel belt of the Middle Loup River, however, exhibits small (≤ 25 m in width and ≤ 1200 m in length) abandoned channels filled with standing or very slow-moving water (Figure 16), and these features are at least partially analogous to the ancient depositional environments of PW architectural elements described herein.…”
