Organonitrophos (OP) is an organic fertilizer which is enriched by nitrogen-fixing and phosphorus solubilizer microbes. This study aimed to determine the effect of the combination dose of OP and inorganic fertilizers as well as the addition of biochar and its interaction on soil fauna (earthworms and mesofauna) in Ultisol soil during the maize growth. This research was conducted at the Integrated Field Laboratory, University of Lampung. The treatment used was a 6 × 2 factorial with three replications in a randomized block design (RBD). The first factor was the combination dose of OP and inorganic fertilizers consisting of six levels, and the second factor was biochar from rice husk consisting of two levels. Earthworm was examined using "hand sorting" method and soil mesofauna using dry extract "Barlesse-Tulgreen" method. The results showed that during the maize growth, the highest population of earthworms and soil mesofauna as well as the highest biomass of earthworm were found in P5 treatment (100% OP). Application of 100% biochar (B1) decreased the population and biomass of earthworms, on the contrary it increased the population of soil mesofauna. Moreover, Shannon-Weaver Diversity Index of soil mesofauna is not affected by the combined fertilizers and biochar.
