摘要

Aims

Soil salinity and sodicity pose significant abiotic stresses that jeopardize global agricultural productivity and negatively affect soil physicochemical properties, microbial communities, and plant metabolism. Traditional reclamation methods are often inefficient, resource intensive, and environmentally unsustainable. Therefore, exploring green-based saline and sodic soil reclamation strategies important for enhancement of sustainable agriculture.

Methods

This research focuses bioamelioration strategies, which  offers sustainable and eco-friendly alternatives for restoring salt-affected agroecosystems. This review highlights the potential of biological interventions, including halophilic microbial inoculants, AMF, algae, and seaweed, to mitigate salt-induced stress by enhancing soil nutrient dynamics, microbial synergy, and rhizospheric stability. Furthermore, biochar, organic amendments, and nanotechnology can improve soil aggregation, ionic equilibrium, and cation exchange capacity, thereby enhancing ion sequestration and leaching efficiency.

Results

Despite their potential, the widespread adoption of bio-amelioration strategies has been developed , which will beimplemented by exploration of microbe-plant-soil interactions, scalability challenges, and region-specific optimization models. Emerging solutions such as engineered microbial consortia, precision bioformulation technologies, and decision-support tools are being developed to address these limitations and facilitate field-level applicability.

Conclusions

This review provides a multidimensional perspective that emphasizes bio-based amendments to bridge the limitations of traditional approaches with cutting-edge biological innovations for soil salinity mitigation, which collectively contribute to sustainable soil management, resilience in saline agroecosystems, and long-term global food security.

Graphical Abstract

The graphical abstract illustrates the integrated eco-inspired biological strategies for sodic soil reclamation, including microbial inoculants, seaweed extracts, algae, mycorrhizal fungi, phytoremediation, biochar, and nanotechnology. These bio-ameliorative approaches improve the soil structure, enhance nutrient availability, and boost plant tolerance to salinity stress. This highlights their synergistic role in promoting soil health and sustainable agriculture. This holistic framework supports eco-friendly, and climate-resilient land restoration practices.
