Sifat Kimia Ultisol di Bawah Tegakan Berbagai Umur Tanaman Kelapa Sawit (Elaeis guineensis jacq.)
Abstract: The purpose of this
research is to determine the chemical properties of Ultisol under the oil palm
stands of different ages between on the oil palm circle, life path and die path
with different depths. This research was conducted by survey method. The sample
collection is done by purposive sampling. The results of the research showed
that the increasing age of the oil palm plantations has increased Ultisol
chemical properties. The chemical properties of Ultisol under the stand of oil
palm age of 18 years is the highest compared to the age of 8 and 15 years. pH
and higher organic-C in the die path than in the circle , and the disc is
higher than in life path. Total-N, available P, exchangeable bases, CEC, and
base saturation is higher in the oil palm circle than in die path, and some
chemical properties of Ultisol in die path is higher than in life path. In
general, the chemical properties of Ultisol at a depth of 0-20 cm have a higher
value than the depth of 20-40 cm.
