This review explores sustainable remediation strategies for saline soils in Ningxia, China, where excessive agricultural water use and an arid climate have exacerbated soil degradation. Key strategies include biochar application to enhance soil structure and nutrient cycling, organic amendments like straw interlayers to boost soil organic carbon and microbial activity, and controlled drip irrigation for effective soil rehabilitation. The review also advocates for an integrated ecosystem approach that promotes biodiversity and addresses the limitations of single-species strategies. Climate-adaptive techniques are emphasized as essential to counter increasing soil salinization due to climate change. Despite the promise of these methods, challenges such as high costs and the need for widespread adoption by local farmers persist. The review calls for optimized, locally tailored solutions that integrate water and soil management practices, aiming to reclaim saline soils and enhance agricultural sustainability in Ningxia and similar regions globally.
