Abstract

KAJIAN BEBERAPA SIFAT FISIKA TANAH YANG DITANAMI KELAPA SAWIT (Studi Kasus Perkebunan Sawit Kelurahan Simpang Tuan, Kecamatan Mendahara Ulu,Tanjung Jabung Timur) Laddy Megayanti1), Zurhalena2) dan Heri Junedi2) Land clearing for oil palm plantations using heavy equipment will affect the physical properties of the soil, namely increasing soil compaction and decreasing soil porosity and soil moisture content. However, along with the growth of plantation crops such as oil palm, it is suspected that it can restore the physical properties of the soil. The aim of the study was to examine the differences in the physical characteristics of the soil at various ages of oil palm and the slope of the slope. The study was conducted in one of the oil palm plantations, Simpang Tuan Village, Mendahara Ulu District, Tanjung Jabung Timur Regency from March to May 2021. The study was carried out using the survey method, selecting representative areas using the Purposive Random Sampling method on oil palm plantation areas with various age (newly planted, 5 years old, and 12 years old) and various marbles (0-3%, 3-8%, and 8-15%) with 3 replications. Parameters observed were soil texture (hydrometer method), soil organic matter content (LOI method), bulk density (gravimetric method), water content (gravimetric method), and soil permeability (de Boods). The results showed that 1). the older the age of oil palm plantations, the increase in organic matter content, total pore space, water content and soil permeability and a decrease in volume weight; 2). The steeper the slope, the greater the weight of the soil volume and a decrease in the organic matter content, total pore space, water content and soil permeability. Keywords: land clearing, oil palm, physical properties, plant age, slope
