ASSESSMENT OF SOIL QUALITY INDEX FOR TEAK FOREST IN DRY LAND, ACEH BESAR REGENCY

This research aims to examine the analysis of the soil quality index on land use type specifically on teak forest on dry land of Aceh Besar Regency, Aceh Province. This investigation targeted multiple specific sites where teak forests are established on dry land. Descriptive techniques based on survey data, field observations, and laboratory analysis were used to conduct this study. Field surveys were conducted to gather primary data, including the overall biophysical conditions of the region, the physical and chemical properties of the soil from observations, and indicators of soil quality through laboratory analysis. The findings indicate that the SQI predominantly falls within the medium range. Factors such as low organic carbon levels, elevated bulk density, pH (H2O), exchangeable potassium (K-exchangeable), phosphorus availability, and reduced total nitrogen content significantly affect these results. To mitigate nutrient leaching and enhance soil organic matter, specific management strategies involving fertilization, pine reforestation, and improved drainage are recommended for these teak forest lands.
