ABSTRACT The rhizosphere, as the primary site of plant–soil –microbe interactions, plays an important role in plant productivity. influence species on rhizosphere soil properties and how this shapes productivity grassland ecosystems remains poorly understood. Therefore, study analyzed changes bacterial community structure metabolites perennial cultivated grassland. aim was to elucidate pathways underlying mechanisms by which physicochemical properties, structure, Taking monocropping grasslands established with three common grass from Qinghai –Tibet Plateau research objects, a comprehensive conducted using replicated field trials. Rhizosphere samples were collected Elymus breviaristatus , Festuca sinensis Poa pratensis . results indicated significant differences productivity, diversity, among grasslands. Among them, ANPP (589.17 g·m −2 ), root biomass (3601.67 moisture (18.15%) Verrucomicrobiota (3.60%) are higher than those while relative abundance Firmicutes (0.82%) is lower that topological characteristics networks varied different species. abundances consisting phenylalanine, proline, raffinose, maltotriose, uridine, 2‐methylbenzaldehyde differed treatments.

Current agricultural practices face numerous challenges, including declining soil fertility and heavy reliance on chemical inputs. Rhizosphere microbial metabolites have emerged as promising agents for enhancing crop health yield in a sustainable manner. These metabolites, phytohormones, antibiotics, volatile organic compounds, play critical roles promoting plant growth, boosting resistance to pathogens, improving resilience environmental stresses. This review comprehensively outlines the mechanisms through which rhizosphere influence health, traits, functional components, yield. It also discusses potential applications of secondary biofertilizers highlights challenges associated with their production practical use. Measures overcome these are proposed, alongside an exploration future development fertilizer industry. The findings presented here provide scientific basis utilizing enhance sustainability, offering new strategies management. Integrating could lead increased productivity, improved quality, reduced dependence synthetic inputs, thereby supporting more environmentally friendly resilient system.
