The experiment aimed to study the change in phosphorus absorption by corn driven by lime, vesicular arbuscular mycorrhizae (VAM), and natural rock phosphate in Ultisol Taman Bogo Central Lampung. A factorial experiment (2x2x4) arranged in a completely randomized block design with three replicates was conducted. The first factor was lime (CaCO3) without and with lime 4 t/ha. The second factor was VAM inoculation without and with VAM inoculation. The third factor was BFA application: 0, 500, 1000, and 1500 kg/ha. The results showed that application of lime in Ultisol Taman Bogo significantly increased P absorption by corn, pH, dry matter yield of corn, and percent VAM infection. VAM inoculation very significantly affected percent VAM infection, but did not significantly affect phosphorus absorption, pH, and dry-matter yield of corn. However, without lime application, VAM inoculation significantly increased P absorption by corn by 11.06 percent. On lime application without VAM inoculation treatment, application of BFA significantly increased P absorption by corn, pH, and dry-matter yield of corn
