Oil palm (Elaeis guineensis) is a major contributor to global vegetable oil production; however, ensuring its sustainability remains critical challenge, particularly concerning soil health. In this study, we investigated the impact of long-term organic matter application as part good management (GSM) practices on plantations and compared it with poor determine presence plant growth-promoting bacteria (PGPB) in communities. The ten-years regular GSM plots led notable improvements chemical properties, including total carbon, nitrogen, available phosphorus, potassium, cation exchange capacity. Metagenomic analysis revealed significantly higher abundance beneficial microbial species exclusively found plots, supporting growth. Furthermore, novel finding emerged from successfully predicted metabolic function PGPB communities using PICRUST2 provided by microbiome. indicated that increased functional enzymes related PGP activities, such nitrogen fixation, phosphate solubilization, potassium phytohormone synthesis. This study underscores significance implementing incorporating eco-friendly materials, matter, enhance health fertility ensure sustainability.
