SOIL ANALYSIS AND MICROBIAL DIVERSITY IN WEST BALI FOREST AREA TO SUPPORT SUSTAINABLE FOREST MANAGEMENT

Abstract

Forest land conversion in tropical areas such as Indonesia threatens biodiversity and ecosystem function. West Bali Forest, located in Jembrana Regency, covers 39.95% of the total forest area in Bali. The goal of this study is to examine the soil conditions in the village forests-managed area, with the aim of promoting sustainable management practices and ecosystem services. The study lasted for seven months, using a purposive sampling technique at a depth of 0–30 cm. The Soil Science Laboratory at Udayana University conducted the soil analysis. We tested several parameters, including total N, organic C, pH, available K, and available P. The results showed that the soil pH ranged from 6.05 to 6.6. The organic C content varied between 0.85% and 3.39%. Total N in the core forest ranged from 0.05% to 0.36%. Available P content ranged from 2.4 ppm (very low) to 10.32 ppm (low). The available K content ranged from 108.14 ppm (low) to 262 ppm (high).
