Assessing soil quality for rehabilitation of salt-affected agroecosystem: A comprehensive review

One billion hectares of land worldwide is affected by several kinds salinity and associated problems. The soil quality (SQ) in salt-affected (SAS) impaired because the presence excess electrolytes, disproportionate Na Ca solution exchange phase, rhythmic changes hydrological cycle, decreasing organic matter, poor vegetative cover, low biological activity, crop residue return. Sodic saline–sodic soils have potential to provide alkaline reactions physical constraints regulate attributes affecting SQ. Because high spatial variability rapid temporal changes, selection simple, robust, cost, high-throughput master indicators for assessing SQ very essential monitoring aggradation or degradation SAS. Therefore, screening developing a minimum dataset assessment SAS an important issue sustainable management these agro-ecologies. We captured from ecosystems different countries discussed problems parameterization Improved optimum functioning needed confirming agricultural productivity food security around globe. This review describes causes drivers sodification/salinization mechanism-oriented rehabilitation options such as application mineral gypsum, flue-gas–desulfurized elemental S, acidified biochar, polymer, salt tolerance mechanisms, other agro-techniques improving Based on assessment, suite site-specific practices are advocated greening prosperity.
