Unlocking Soil Fertility and Enhancing Plant Health: The Vital Role of PGPR

Abstract

Plant Growth-Promoting Rhizobacteria (PGPR) have gained momentum because of their multiple activities on the betterment of the fertility of soils and also the normalcy of plant health. This overview describes the ways that the PGPR functions (acquisition and mobilization of nutrients, regulation of plant growth, biocontrol, suppressing diseases, and reducing abiotic stresses). Through transition and emphasis on different aspects, the article explains the delicate interconnection between PGPR and plant growth and soil management as they can fix nitrogen, dissolve phosphate, produce Siderophores, and regulate ethylene levels. Furthermore, they function in plant hormone production, bacteria and antimicrobial substance emission, and induction of the systemic resistance to the pathogens which contributes to their importance in agroecosystems. Key plausible PGPR implementations including biofertilizers and biocontrol agents are elucidated and highlighted as the tools to promote crop yields and lessen ecological footprints. Nevertheless, quite a few barriers, like strain specificity, mass production, formulation, and co-relation with contemporary agricultural practices, do not enable the perfect implementation of PGPR technologies. The future expectancy of the problem prevails and the discussion of the science behind the production of PGPR can now be used as a tool for sustainable agriculture practices. Treating these issues will therefore smoothen the path for applying PGPR as the vital agent for maintaining sustainable world agriculture against the ever-increasing environmental problems.
