Abstract
The purpose of this research is to determine the physical properties of Ultisols under oil palm stands of different age and evaluate the level of soil compaction. The research was conducted by survey method. The results of observation showed that the increasing age the oil palm stands caused the physical properties of Ultisol soil, such as soil aggregate stability, pore space total, infiltration rate, soil permeability, and water content of field capacity increased, while soil bulk density, soil particle density, and soil penetration decreased on die path, the circle, and life path in the depth of 0 – 20 cm and 20 – 40 cm. The increasing age the oil palm stands showed that the soil aggregate stability, pore space total, infiltration rate, soil permeability, and water content of field capacity on die path is higher than on the circle, and the circle is higher than on life path, while soil bulk density, soil particle density, and soil penetration on die path is lower than on the circle and the circle is lower than on life path in all age the oil palm stands in the depth of 0 – 20 cm and 20 – 40 cm. The increasing age the oil palm stands decreased the soil compaction level in the depth of 0 – 20 cm and 20 – 40 cm on die path, the circle, or life path.
