• Climate change-driven salt stresses jeopardize the crop growth, and productivity. • Nano-agrochemicals enhance salt tolerance via targeted root microbiome modulation. • Panomics integration reveals key insights in nano-microbial establish salt tolerance. • Findings new molecular targets and mechanisms expedite the making of salt-smart crops. Soil salinization threatens global food security by compromising approximately 33% of irrigated agricultural fields, with projections indicating a 50% increase in affected areas by 2050. Recent advances at the intersection of nanotechnology, microbiome engineering, and multi-omics approaches have revealed unprecedented opportunities to enhance plant salt stress tolerance through targeted modulation of the root-associated microbiome. In this review, we comprehensively discuss emerging evidence demonstrating that nano-enabled agrochemicals can selectively enrich beneficial microbial consortia in the rhizosphere, enabling salt stress tolerance through multiple complementary mechanisms. Smart nanomaterials, including biodegradable chitosan-based nanocarriers and metallic nanoparticles with controlled dissolution kinetics, have been shown to precisely deliver bioactive compounds that produce microbiome assembly, promoting colonization by key salt-tolerant taxa such as Halomonas, Azospirillum, and specialized fungal endophytes. Integration of spatially-resolved metatranscriptomics with metabolome profiling has elucidated previously unrecogniz...
