A field spectroradiometer was used to measure radiation from samples of seven Indiana soil series in a spectral range from 430 to 730 nanometers (nm). This range includes most of the visible portion of the spectrum. Percent reflectance of the soils was calculated as the ratio of the radiation of the target soil divided by the incident radiation. Reflectance curves were obtained for the soils in both wet and dry conditions with the crust broken and for some of the soils in a dry crusted condition. Preliminary results obtained during evaluation of the instrument indicated a capability for characterizing the radiance properties of various soil series. |
