Abstract
Deforestation at a high and alarming rate threatens the planet's biodiversity with extinction and causes land degradation. Rehabilitation of degraded forests and lands for enrichment of ecosystems and sustainable use of degraded areas is essential at regional and global scales. An assessment was conducted to compare the soil physical and chemical properties from a rehabilitated forest and a logged: over forest in Universiti Putra Malaysia Campus Bintulu. Results showed bulk density of soil surface in rehabilitated forest (1.0763 g cm-3) was significantly higher than that of logged-over forest (0.8166 g cm-3). Sand and silt content at depth 15-30 cm for both forests were significantly different. However, there was no significant difference in clay content for both forests. Significant differences were observed for organic C as well as total N in the logged-over forest for different soil depth. Significant difference was also observed for total N at 15-30 cm depth for different forest. Available P in both forests showed significant difference in every direction of the statistical analysis. Available P in the soil from rehabilitated forest was significantly higher than the logged-over forest. Soil pH (1 M KCl) from both forests ranged from 3.63 to 3.83 while for pH (H20) ranged from 4.52 to 4. 78. Similarity in the soil properties of both forests despite the difference in age concluded that forest rehabilitation to amend the soil properties of a degraded land seems promising.
