The purpose of this community service activity was to socialize the use of bioorganic fertilizer-P on soybean plants in order to reduce farmers' using inorganic fertilizers. Bioorganic-P fertilizer is an organic fertilizer that has been enriched with phosphate solvent Rhizobacteria (PSR). This activity uses a participatory approach method, in which the target group is actively involved at all levels of activity. The target partner is the "Mele Maju" farmer group in Selat Village, Narmada District, West Lombok Regency.The beginning of this activity was building an agreement between the service team and the target group through a group discussion activity (FGD). The next activity was counseling about organic fertilizers, bioorganic-P fertilizers, their roles, and their benefits for plants, especially soybean plants. After that, the practice of making bioorganic –P fertilizer was carried out. Furthermore, a demonstration plot of integrated fertilization was carried out on farmers' land to show differences in yields with or without using a combination of bioorganic-P fertilizers and inorganic fertilizers. The results of the demonstration plot on soybean showed that the combination of bioorganic-P fertilization and 75% of the recommended fertilizer dose was higher than 100% of the recommended doses. This service activity received a positive response from the target farmer groups.
