Abstract: Land use and forest
harvesting (timber and non-timber) could lead to the opening of ground cover.
This activity would lead to disruption of physical properties, chemical and
biological soil, especially in the top soil.The purpose of this study was to
determine the physical properties of soil on different types of land use, i.e
in primary forest, agroforestry and cocoa plantation in the sub-watershed Wera
Saluopa which is part of the sub-watershed area of Maraoa Koronjongi. The study
was conducted from May till July 2013, on the various types (primary forest,
cocoa plantation and agroforestry land) for soil sampling, laboratory analysis
of soil samples and analysis of data. Study site selection was purposive
sampling where Saluopa Wera Sub-watershed, in the village of Leboni, District
Puselemba Pamona, Poso Regency of Central Sulawesi.The results showed that the
physical properties of the soil at various types of land use in the
sub-watershed of WeraSaluopa have sandy loam soil texture, soil permeability
varies from very slow (primary forest) to very fast (agroforestry), soil
porosity from 49.93% (primary forest) to 54.04% (cocoa plantation) with high
bulk density ≥ 1.0. Hence, the highest of soil organic matter was in primary
forest(7.09) followed by cocoa plantation (5.86) and agroforestry land (4,12).
