P fertilization and application of organic matter are some of the efforts to increase the P availability in the soil. The application of organic matter enriched with phosphate fertilizer increases the P-available in soil. This study therefore aims to determine the effect of applying organic matter enriched with phosphate fertilizer on several chemical properties as well as productivity of lowland rice fields in Bogor Regency. The study was conducted by UNB’s greenhouse and paddy fields in Darmaga, Kemang and Sukaraja Districts, Bogor Regency. Organic material in the form of cow dung with a dose of five levels was enriched with phosphate fertilizer in the form of H3PO4 in an equal dose, and incubated for 30 days. Subsequently, the phosphate enriched mixture with the best incubation result for fertility level was applied in the paddy fields. The results showed about 60 tons / ha of organic matter 225ppm P of Posfat fertilizer had optimum fertility after 30 days incubation, followed by 40 tons / ha of organic, enriched with the same dose of phosphate fertilizer. In addition, Latosol soil, Bogor Regency, where organic matter enriched with about 225ppm P of phosphate fertilizer in all locations had the same soil fertility and lowland rice productivity, meaning no significant difference was obtained using the same dosage of organic matter. Meanwhile, soil fertility in the form of pH, available CEC and P increased, as well as lowland rice productivity, increased with the application of organic matter (60 tons / ha).
