Soil water in the coastal zones is more vulnerable to salinization. Soil-water vulnerability assessment is an effective tool for soil-water management. This study used the DRASTIC model, which is based on seven factors viz: Depth to soil water, recharge, soil-water bearing layer, soil media, topography, impact of root zone, and hydraulic conductivity to evaluate soil-water salinization potentiality of Ben Tre province.

Ebook "Use of microbes for the alleviation of soil stresses, Volume 1" describes the most important details and advances related to the alleviation of soil stresses by soil microbes. Comprised of seven chapters, the book reviews the mechanisms by which plant growth promoting rhizobacteria (PGPR) alleviate plant growth under stress; the role of mycorrhizal fungi on the alleviation of drought stress in host plants; how PGPR may alleviate salinity stress on the growth of host plants; and the role of PGPR on the growth of the host plant under the stress of sub optimal root zone temperature.

Coastal dunes are characterised by plant species adapted to harsh conditions. Salinity and other factors (soil pH, nutrients, and climate events) vary along the landward gradient. The current study investigated the effects of environmental factors on the occurrence and composition of coastal dune plants. Ellenberg ecological indicator values (EIVs), species tolerance values (TVs), and species niche models for salinity, nutrient availability, and soil reaction were determined.

In paper "Fine root vertical-seasonal distribution of Robinia pseudoacacia in relation to abiotic factors in a chronosequence in coastal saline alkali land of the Yellow River Delta, China", FRB, FRL, FRSA, SWC and soil nutrients increased, while SRL and SSC decreased with increasing stand age. Vertically, fine roots were concentrated in a 0–20 cm soil layer. SRL, SWC and SSC increased, while soil nutrients decreased with increasing soil depth.

The study "Biochar mitigates salt stress by regulating nutrient uptake and antioxidant activity, alleviating the oxidative stress and abscisic acid content in cabbage seedlings" was conducted as factorial completely randomized design with two factors; salinity levels (0 and 150 mM NaCl) and biochar doses (weighed at the rate of 0%, 2.5%, and 5% by soil weight). Growth parameters such as stem diameter, leaf area, shoot fresh weight, root fresh weight, shoot dry weight, and root dry weight of cabbage seedlings treated with 150 mM NaCl were lower than the control.

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.

Reactive oxygen species (ROS) are byproducts of normal plant metabolism and their production is elevated under environmental stresses such as drought, extreme temperature, and salinity. Among these, salinity is a worldwide problem that impacts the fertility of arable lands and sustainability of food security, which is getting more attention due to climate change. Halophytes can survive and reproduce in soils containing high concentrations of salt and have developed adaptation mechanisms at physiological, biochemical, and molecular levels including maintenance of ROS metabolism.

Our study sets forth the outcomes of an interdisciplinary project conducted in order to fill the information gap on the management of a wetland ecosystem, in the case of a protected area on the south-eastern coast of Turkey. The hypothesis of the study is that the pattern of species composition reflects soil salinity level and some species can act as relevant indicators. The study aimed to discover a relationship between soil salinity and vegetation composition and establish some indicators useful for monitoring.
