This report includes the discussion of the genesis and clarification of classification of reddish brown latosols, yellowish brown latosols and red yellow podzolic soils on basis of soil forming factors and some major characteristics. In view of these general findings some evidence of these three groups being found in the past is clarified. It may be summarized as follow:
1. It is hard to explain the genesis of the reddish brown latosols from the recent climatic data of the lowland in Taiwan. As podzolization is taking good in process in the rolling hill zone, the reddish brown latosols have been podzolized gradually. Laterization and Podzolization are both being found on yellowish brown latosols and red-yellow podzolic soils, and the former have modified with some limonization, but some of them are affected by its parent material, so that it may be called as young soils.
2. The genesis of reddish brown latosols is not the result of recent climate, but its parent material was derived from the weathering rDsidual products of the Plistocene and Miocene age. The reddish brown latosols being found in Taiwan were mostly developed on the pleistocene terrace table land. It confirms the .theory of the pedologists abroad.
3. According to the 7th approximation of soil classification U.S.D.A. 1960, as rhodochrults which have been called reddish brown latosols, they are drived from primary basic igneous rocks, but many of reddish brown latosols of Taiwan are developed from sedimentary rocks and metamorphic rocks also.
