Description	A fast and convenient soil analytical technique is needed for soil quality assessment and precision soil management. The main objective of this study was to evaluate the ability of visible (Vis) and near -infrared (NIR) reflectance spectroscopy to predict paddy soil properties in a typical Malaysian paddy field. To assess the utility of specroscopy for soil physical characteristics (bulk, denstiy, moisture content, clay, silt and sand) prediction, 118 soil samples were used for laboratory analysis and optical measurement in the Vis-NIR region using and analytical spectral device (ASD) FieldSpec spectroradiometer (350 -2500 nm). The Savitzky-Golay algorithm and stepwise multiple linear regression (SMLR) were then applied to preprocess, model, and predict the properties on the basis of their spectral reflectance within the Vis-NIR range. One-third of the samples (40 samples) were withheld for validation purposes. The study revealed that Vis and NIR spectroscopy calibration models for all the measured s A fast and convenient soil analytical technique is needed for soil quality assessment and precision soil management.
