TEST Database of soil in Jordan

This study enlarges the database by the results of 160 bulk samples that were collected systematically from the soil surface at 40 locations. In addition to soil color and contents of Fed, we explore mean soil reflectance spectra (MSRS) measured by Analytical Spectral Devices (ASD), and analyze the morphological conditions of the spectra referring to the effects of iron oxides on spectral behaviors. Research domain: Soil Sciences Research question: Relationships between spectral features, iron oxides and colors of surface soils in northern Jordan
