| Outline of Final Research Achievements |
The characteristics of a specific phosphorus fraction as unused resources accumulated in Andosols were investigated. Potentially available phosphorus (PAP) in Andosols was estimated by substrate-induced respiration method. Amounts of PAP in various soils were compared with those of other phosphorus components. The results indicated various availability of phosphorus resources in the soils tested. Recovery and recycle of phosphorus resources accumulated in Andosols was investigated by cultivation of some herbaceous plants.
