Summary Rhizosphere microbiomes are pivotal for crop fitness, but the principles underlying microbial assembly during root–soil interactions across soils with different nutrient statuses remain elusive. We examined in rhizosphere and bulk of maize plants grown under six long‐term (≥ 29 yr) fertilization experiments three soil types middle temperate to subtropical zones. The communities was primarily driven by deterministic processes. Plant selection interacted regimes shape structure function microbiomes. Predictive functional profiling showed that, adapt nutrient‐deficient conditions, recruited more rhizobacteria involved availability from soil, although these functions were performed species. Metagenomic analyses confirmed that number significantly enriched Kyoto Encyclopedia Genes Genomes Orthology categories community higher without than fertilization. Notably, some key genes carbon, nitrogen, phosphorus cycling purine metabolism dominantly fertilizer input. In conclusion, our results show selects microbes at interface based on traits beneficial its own performance, rather selecting particular
