The objective of this research was to examine soil quality and the diversity of soil macrofauna in oil palm plantations in relation to the application of bio-fertilizers. The study compared various soil quality parameters, including soil texture, moisture content, pH levels, and temperature.The analysis of soil samples from areas using bio-fertilizers revealed the following results.The first sample was characterized as clay loam, with a soil moisture level of 7, a pH of 7.0, and a temperature of 28°C.The second sample consisted of clay, with a soil moisture level of 8, a pH of 7.0, and a temperature of 26°C.The third sample was identified as loam, with a soil moisture level of 2, a pH of 8.0, and a temperature of 38°C.
