Abstract: The study aims to search for the hyperspectral bands most sensitive to soil organic matter content and the retrieval model. In the field, the spectra of soils samples were measured by an ASD PRO FR2500 in the 350~2500nm regions.Then the hyperspectral reflectance data were transformed to several Organic matter Identification Index (OII). According to the result of the correlation analysis, the 511nm region was regarded as the best detecting band for soil organic matter content. Moreover, the accuracy of retrieval model is the highest using the OII as the independent variable in the linear model.

Key words: Soil, Organic Matter Content, Hyperspectral, Organic matter Identification Index (OII)
