Annotation<\/strong>. This study reviews state-of-the art re\u00adgarding visible and near-infrared (Vis-N\u0130R) spectro\u00adscopic modeling of soil properties. The main emphasis was given to characterising the principles of Vis-N\u0130R spectroscopy, factors affecting soil spectrum, fun\u00adda\u00admental vibrations and combinations, preparation of soil samples for spectral measurements, pre-processsing and transformations of the spectral data. Furthermore, mul\u00adtivariate calibration methods, important wavelengths for predictive models and factors affecting model per\u00adfor\u00admances were comprehensively characterized with res\u00adpect to multiple study cases. Spectral reflectance and ab\u00adsorption features of soil is attributed to soil mineralogy, water and organic matter content as well clay type and content. The review of large amount of published stu\u00addies show that the robustness of the prediction models was dependent multiple factors, such as accurateness of reference data, spectral measurements and pretreatment methods, modeling approach and the number of samples involved in calibration. The main superiority of Vis-N\u0130R spectroscopy is that this technique is non-destructive, cost-effective and cpapble of determining multiple soil properties from a single spectrum. Recent studies have significantly developed methods of calibration and spectral databases that necessitates its application from experimental to operational phase. In spectroscopic mo\u00addeling, linear regression models, especially partial least squares regression model remains most used. Mean\u00adwhile, the recent development of data mining techniques may pave the way for improving calibration methods.<\/p>\n
