The composite sample were collected from 0-20 cm, 20-40 cm, and 40-60 cm of soil depth in 12 location. The analysis of soil included: soil pH, cation exchange capacity (CEC), organic matter (OM), and base saturation (BS). The results showed that the most area in acidity, cation exchange capacity (CEC), organic matter (OM), and base saturation (BS) are dominant very low. For improving soil quality, we suggestion adding lime and fertilzer also growing protecting crops for prevent high rainwater directly to land field so that leaching was not occurred.
