Sifat Fisika dan Kimia Tanah pada Tegakan Eucalyptus pellita di Hutan Tanaman Industri PT. Arara Abadi, Distrik Sorek, Provinsi Riau

Eucalyptus pellita is one of the main species in Industrial Plantation Forests (HTI) due to its rapid growth, short harvesting rotation, high productivity, and resistance to pests and diseases. However, land clearing and repeated harvesting activities may degrade soil physical and chemical properties. This study aimed to analyze the characteristics and differences in soil physical and chemical properties under Eucalyptus pellita stands aged 0–4 years in the Industrial Plantation Forest of PT Arara Abadi, Sorek District, Riau Province. A quantitative descriptive approach was applied with purposive sampling, followed by laboratory analysis. The results revealed that the soil physical properties were dominated by sandy clay loam texture with high bulk density (>1.65 g/cm³). This condition limits nutrient-holding capacity and potentially restricts root growth. Based on the chemical analysis, the soil was classified as very acidic (pH 3.92–4.34), with very low until low Cation Exchange Capacity (2.028–6.931 meq/100g), very low C-Organic (0.25–0.62%), very low until low Nitrogen (0.07–0.12%), very low Phosphorus (0.01–0.02%), and very low Potassium (
