Fluctation moisture properties in the application of soil dielectric measurement in the North Bengkulu District, Indonesia

Information about soil moisture in the root layer is very important evaluating water availability for plants, erosion rates and various other hydrological characteristics. Previous research has found a technology measuring dielectric properties as estimator that can be carried out quickly field. The purpose of this study was to apply dielectricity estimating characteristics situ field at North Bengkulu Province. Five land units Regency, Indonesia, have been selected experimental sites. At each location, profile excavated depth 100 cm, basic were described analyzed detail laboratory. variables measured are measurement soil, effective horizon horizon. laboratory texture, organic matter layer, aggregate stability 0-10 cm time measurement, groundwater relationship between data on with balance variable analysis measurements field, then determined using regression analysis. results showed five locations studied had different fluctuations. Of four independent tested (percentage sand, silt, clay carbon) content sand used predictors capacity. Because weak correlation permanent wilting point water, available only predicted from content.
