Soil Nutrient Enrichment Induces Trade-Offs in Bacterial Life-History Strategies Promoting Plant Productivity.

ABSTRACT: Despite the global prevalence of anthropogenic soil nutrient enrichment, its impacts on the trade-offs in microbial life-history strategies remain poorly understood, which is critical for agroecosystem productivity. Here, large-scale observational studies are integrated with controlled experiments to systematically evaluate how soil nutrient enrichment affects bacterial functional potential and growth-rate potential, ultimately determining microbial functions and plant productivity. These findings reveal stark contrasts between nutrient-poor open field (OF) and nutrient-rich greenhouse (GH) soils across multiple paired sites using 16S rRNA gene amplicon and metagenomic sequencing. OF microbial communities dominated by oligotrophs have higher taxonomic diversity, larger average genome sizes
