There were 5 land use types, those were mixture farm, paddy soil, secondary forest, cinnamon, and coconut. The results showed that physical nature of soil under mixture farm, paddy soil, secondary forest, cinnamon, and coconut varied at texture (dusty plates), organic contents (high-very high), slowly drainage pore (PDL) and pore of water available (PAT) which were not significantly different among the five land uses. Permeability of total pore space (TRP) and fast drainage pore (PDC) were high at land use of cinnamon and not significantly different at land uses of paddy soil, secondary forest, and coconut. Key word : soil physical characteristics, land uses.
