“…After several years of growth, the mean soil salinity, initially similar in all vegetation types, had decreased by 22.2 and 20.7 g kg -1 in soil cultivated with T. chinensis and L. chinense, respectively. Our findings are comparable to numerous field studies that have confirmed the capacity of T. chinensis and L. chinense to reduce soil salinity [20][21]. Salt leaching via water Fig.…”

“…In addition, halophytes such as T. chinensis and S. salsa could absorb large amounts of salt from the soil, and weakened soil salinity [6]. Ado et al [21] reported that salt accumulation in plant biomass contributes significantly to soil desalinization, while salt accumulation in plant biomass contributed 22-35% of soil desalinization. This suggests that salt accumulation in plant biomass decreased soil salinity considerably.…”

Soil salinity is a crucial constraint in the potential utilization of land resources in the coastal regions of northern China [1]. Most of the lands within these areas are covered with salinized soil and are accompanied by shallow underground water [2]. Excess salinity and alkalinity plagued seed germination and plant growth, and led to environmental degradation [3]. In order to improve these conditions, local governments have launched costal ecological restoration projects, including planting halophytes, to recover degraded vegetation and reduce soil salinization. Halophytic plants can grow well and produce high biomass in saline environments

“…Previous studies have illustrated that the secretion in plant roots of organic acids (e.g., citric and malic acid) tends to decrease soil pH (Kayama, 2001). Furthermore, better development of root systems could increase the soil porosity, which may also contribute to soil desalinization via leaching (Ado et al, 2019). Both of these mechanisms could apply to Miscanthus , due to its well‐developed root and rhizome system.…”

Phytoremediation using Miscanthus is a valuable technique for the restoration of saline‐alkaline soil, but the potential is not quantified. To assess this potential, a 5 years field experiment was conducted on saline‐alkaline soils with three genotypes of Miscanthus and an unplanted control. The bulk soil (0–20‐cm depth) physicochemical properties were measured annually from 2015 to 2018, while the bacterial and fungal community structures of the rhizosphere soil were investigated by high‐throughput sequencing after 5 years under Miscanthus (2018). The results showed that Miscanthus cultivation on saline‐alkaline soil reduced soil salinization and improved soil fertility on this site. Specifically, compared with the blank control, the five‐years Miscanthus cultivation (mean of three different genotypes pooled) decreased the soil pH by 0.33 units (8.78–8.45) and electrical conductivity by 23.4 μS/cm (226.7–203.3 μS/cm), as well as increasing soil organic matter content from 18.9 to 34.9 g/kg and total potassium content from 15.2 to 18.0 g/kg. In addition, the soil improvement was more pronounced with a longer duration of growth. Miscanthus remediates saline‐alkaline soils by altering the microbial community compositional abundance rather than its diversity. The improvement is due to enrichment of beneficial bacteria leading to soil desalinization (e.g., by Gemmatimonadaceae), litter decomposition (e.g., by Chitinophagaceae), plant growth promotion (e.g., by Micrococcaceae), and the reduction of harmful fungi (e.g., Pleosporales and Chitinophagaceae). Soil pH, electrical conductivity, organic matter, and total potassium were the main physicochemical properties affecting bacterial and fungal communities. Our results quantify the soil improvement potential of Miscanthus and clarify the underlying microbial mechanisms, laying a solid foundation for further implementation of saline‐alkaline soil phytoremediation using Miscanthus. In the future, more extensive multi‐location trials are required to assess if these improvements are seen across a wide diversity of environments.

The improvement of saline and sodic soils aims to reduce the dissolved salts in the soil solution. In this context, an integrated management approach is required, which not only improves its effectiveness in improving soil properties but also increases water productivity and yields. To mitigate the negative effects of soil salinity, improvement of soil properties and yield –water productivity of rice plant, a field trial was carried out at El-Hamoul region, Kafer El-Sheikh, Egypt, during the summer seasons of 2019 and 2020. The experiments were conducted in split plot design, with three replicates. The main plots were assigned to soil amendments (control, compost (C) 10.0 Mg ha-1, gypsum (G) 100% from gypsum requirement 13.512 Mg ha-1 and G+C).Sub main plots were assigned to foliar application (control (tap water), compost tea (50 L ha-1), proline (3.6 g ha-1), and combination of compost tea + proilne). Generally, results showed that the impacts of main plots were in the following order: compost + gypsum ˃ gypsum ˃ compost ˃ control in both growing seasons. Also, soil amendments had a significant effect on decreasing some soil chemical properties i.e. pH, EC, ESP and increasing of CEC compared control treatment. The treatment compost +gypsum more pronounced the other treatment on soil bulk density and total porosity. Soil basic infiltration rate (IR) and hydraulic conductivity (K) high significantly increased by application of compost, gypsum and gypsum + compost and recorded the highest value by application of compost + gypsum. Chlorophyll, proline content, 1000-grain weight, straw and grain yield of rice were significant increased and recorded the highest values due to the interaction between compost + gypsum and foliar of compost tea and proline during two growing seasons. Water productivity (WP) and productivity of irrigation water (PIW) for grain yield of rice were high significantly increased and recorded the highest values due to the interaction between soil amendments, compost tea and proline. Total return, net return, benefit cost ratio and total return from water unit for rice yield were significant increased with treatment and recorded highest values due the interaction compost + gypsum and foliar application of compost tea and proline.
