The stability and availability of soil reflectance records were evaluated using a modified real-time soil spectrophotometer. The results clarified that the reflectance was usable in the wavelength range of 550-1650nm. Using the 857 bits of scanning data obtained from the field experiment, the mean of distances between the soil and the sensor probes was estimated to be about 86mm with 3.3mm standard deviation. Simulations of illumination and reflection indicated that a distance of 55-90mm can provide a stable condition to get correct soil reflectance, and that a variation of the distance can affect the apparent soil absorption of light energy. Correct estimation of soil parameters requires distinctive calibration models for the soil spectrophotometer.
