Worldwide ~831 million hectares of land are salt-affected (SAS). A considerable area of SAS is sodic in nature and carries a considerable quantity of Na and carbonate/bicarbonate, with Na-saturated clay/mineral, which have the potential to supply OH− than Ca ions. The physico-chemical properties and microbial activities of this soil are deleteriously affected by the disproportional availability of CO32−/HCO3− of Na and have serious problems with crop productivity. The projection on climate change rising temperature, elevated CO2 concentration, and evapotranspiration may affect soil sodification and salt dynamics. For restoration of sodic soil, an application of external Ca2+ or acid former is recommended to neutralize carbonate and bicarbonate. Gypsum is the cheapest and most readily available amendment for sodicity reclamation. With limited availability and questionable purity of gypsum, alternate amendments are being searched from time to time. Different approaches have been suggested to apply inorganic in conjunction with organic materials to reclaim such soils. This chapter focuses on selected studies that have identified several materials like polymers, nanomaterials, acidified biochars, elemental sulfur, municipal solid waste compost (MSWC), and flue gas desulfurization gypsum (FGDG) and have the potential to replace gypsum as an amendment in future. Practical issues associated with these materials warrant scientific solutions are also highlighted. Under precise management strategies, climate change mitigation and adaptation strategies are described for pedogenic processes and soil properties. This generated information can be utilized for developing soil sodicity reclamation strategies for land degradation neutrality under changing climatic conditions.
