| Summary: | Soil characteristics are important to evaluate the performance of planted seedlings for reforestation purpose. A
study was conducted in order to determine the soil characteristic under reforestation activities to ensure the
proper piarming of reforestation effort in the future. Study sites were established in the reforestation areas planted
with Dryobalanops beeearii in the year 2005 (DB05) and 2008 (DB08). In these sites, soil samples were
collected at the depths of surface layers (0-10 cm) and subsoil layers (30-40 cm) for determination of
physicochemical properties. The finding showed that the soils in all studied sites were strongly acidic nature with
pH (H20) of less than 5, even at surface soil with sandy texture resulted from its parent material. The total C in
DB08 (65.2g kg·l
) were significantly higher than DB05 (34.5g kg'l) perhaps due to the accumulation of litterfall
mainly from pioneer tree species. The soils in DB05 showed higher bulk density (1.l9gcm'l) and lower porosity
level (55%) as compared to the soils in DB08 due to the differences of clay content in soil texture. Soil texture
were different for both soil profiles, DB05 site showed sandy texture and DB08 sites were classified into light
clay texture from "feel" method observation. In term of soil physicochemical properties between planting lines
and under tree crown, the pH (H20) was significantly higher under tree crown at both sites compared between
lines planting. Whereas, the soil bulk density, porosity and total C showed not significantly difference at both
sites. An important implication of this study was soil physical and chemical properties should be taken into
account as an important indicator when planning reforestation activity. |
