| ABSTRACT |
| The transformation of organic P (Po) from organic manures in two types of soils (ultisol and entisol) and the influences of external addition of organic substance or inorganic P (Pi) on Po under the condition of the 60% maximum water capacity were investigated. The results obtained from Po fractionation experiments indicated that all the Po fractions except for the highly resistant Po fraction decreased during incubation. Application of pig feces and cow feces could largely increase each fraction of Po in the soils. |
