SIFAT FISIK DAN KIMIA TANAH PADA BERBAGAI KETINGGIAN TEMPAT DI HABITAT EBONI (DIOSPYROS CELEBICA BAKH.) DAS SAUSU SULAWESI TENGAH
ABSTRACT: The commercial
utilization of ebony and the encroachment of its habitat to be converted into
various community necessities have led to the decline of ebony species in their
natural habitat. The physical and chemical properties of soil are a vital
element of the habitat for the growth of vegetation, including in the ebony
species. This study aimed to investigate the physical and chemical properties
of soil at various altitudes in the Sausu Watershed, Central Sulawesi. This study was conducted in the Sausu watershed,
Central Sulawesi, which is a natural dispersion area for ebony. Completed
composite soil sampling was conducted at three altitudes, i.e., 100-<250 m
asl, 250-<400 m asl and 400-550 m asl. Subsequently, the samples were
analyzed at Soil Science Laboratory of Faculty of Agriculture, Universitas
Tadulako. It was carried out from February to May 2015. The results indicated
that the slope and back at various altitudes of the Sausu watershed have
insignificant effect on the physical and chemical properties of soil in ebony
habitat. The properties, including the soil texture, permeability, bulk density
or soil porosity, soil chemical properties, demonstrate the acidity level of
“sour to acid”. Meanwhile, the availability of organic-C, N, P, K is classified
as very low, low and moderate. The criteria of CEC is moderate to high towards
fertile soil, but accompanied with moderate and high C/N ratios and very low,
low and high base saturation.
