Abstract:
This study aims to determine the change of the physical properties of soils types various under stands of oil palm (Elaeis guineensis Jacq.) is applied oil palm empty bunches (OPEB). The research was conducted by survey method. The research showed that giving oil palm empty bunches (OPEB) on soil type Podsolic Haplik, Podsolic Plintik, Kambisol District and District Gleysol the understory palm oil can improve the physical properties of the lower bulk density and particle density, and increased total of pore space, permeability, infiltration rate and water content in the depth of 0 - 20 cm. Decrease of bulk density and particle density, and increase of permeability and water content of soil applied Podsolic Haplik oil palm empty bunches (OPEB) is lower than on land Podsolic Plintik, Kambisol District and the District Gleysol which is not applied oil palm empty bunches (OPEB). Total of pore space increases on the soil Podsolic Plintik, and infiltration rate increases on the District Kambisol applied oil palm empty bunches (OPEB).
