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 aggravat...

Rising sea levels are expected to cause salinization in many historically low-salinity tidal wetlands. However, the response of soil extracellular enzyme activities wetlands and their links organic carbon (SOC) decomposition largely unknown. Here, we conducted a global meta-analysis examine effect on hydrolytic oxidative carbon-acquiring relationships with SOC storage The results showed that re...

Arid and semi-arid lands cover more than one-third of the earth’s terrestrial area are typically characterized by rainfall scarcity, higher temperatures evapotranspiration, salinization, nutrient-poor soil, a paucity vegetation [...]

This study addresses the growing problem of soil salinity. In Mediterranean regions, disused solid waste landfills have given rise to disturbed ecosystems. At such sites, both mobile soil anions and cations have toxic effects on plants. Thus, detailed knowledge of these effects is needed for the phytoremediation of soils facing the problem of salinization. In this study, high chloride levels we...

Soil and water resources can be severely degraded by salinity when total salt input exceeds output in irrigated agriculture. This study was conducted to examine partitioning of Ca2+, Na+, and Cl- between soil and soybean [Glycine max (L.) Merr.] plants under different irrigation regimes with both field and modeling assessments. In drip and sprinkler treatments, the irrigation water was salinize...

Soil salinization is one of the most important factors impacting plant productivity. About 3.6 billion of the world's 5.2 billion ha of agricultural dry land, have already suffered erosion, degradation, and salinization. Halophytes are typically considered as plants able to complete their life cycle in environments where the salt concentration is above 200 mM NaCl. Salinity adjustment is a comp...

In coastal China, there is an urgent need to increase land area for agricultural production and urban development, where there is a rapid growing population. One solution is land reclamation from coastal tidelands, but soil salinization is problematic. As such, it is very important to characterize and map the within-field variability of soil salinity in space and time. Conventional methods are ...

The ability to inventory and map soil salinity at regional scales remains a significant challenge to scientists concerned with the salinization of agricultural soils throughout the world. Previous attempts to use satellite or aerial imagery to assess soil salinity have found limited success in part because of the inability of methods to isolate the effects of soil salinity on vegetative growth ...

Research on the variation in soil water, heat, and salt unsaturated zones during freeze–thaw process has great significance efficiently utilizing water resources preventing salinization. The field experiment was carried out with lysimeter as test equipment to analyze characteristics of process, profile content, main ion content three textured soils groundwater table depth 0.5 m. results showed ...
