Problem Soils: Managing Sandy Soils (Quartzipsamments)

[addw2p name=”problemSoils”]


The extent of quartzipsomments in Malaysia has not been reported. However, they are known to occur extensively besides mining or ex-mining areas and flat river basins. Some of these soils are classified as Sg. Buloh, Subang, Nangka, Lintang and Jambu series. The major limitations of these soils mirror those of podzols except that perched water table does not exist.

The management procedures for oil palms on these sandy soils are similar to those on podzols except that scupper drains are not dugged. Our experience with plantings on these soils has been fortunate because they occur in high rainfall regions of Central Perak and Southern Kedah. Their yield performances are shown in Figure 7 also.
