Short summary

P release capacity of soil amended with RP varied between 6.0–11.5 mg kg-1, while the soluble P fertilizers, i.e., SSP and DAP, displayed a maximum of 73 and 68 mg P kg-1 at the start of the experiment (day 0). However, the P release tendency from SSP and DAP declined during incubation and at the end 82 and 79% of P initially present had been lost from the mineral pool. Integrated use of PSB and PM with RP in ½RP+½PM+PSB treatment stimulated P mineralization by releasing a maximum of 25mg P kg-1.
