In this study, the soil characteristics analyzed is: soil texture, caution exchange capacity, base saturated, organic matter, P and K contents. Analysis results showed that most of Tabanan regency paddy soil had a medium physical-quality, very low to low chemical-quality, low biological-quality, and low productivity.
