Abstract

A soil measurement probe (21) includes a window (38) mounted in an opening (40) in the outer surface (34) of the probe, a light source (42) disposed within the probe and directed toward the window for illuminating the soil in situ, with light of wavelengths corresponding to the colors red, blue and green, in succession. A photo-detector (44) disposed within the probe is directed toward the window, the photo-detector responsive to light of each of the first and second wavelengths as reflected from the soil in situ. The probe is useful for measuring the color of the soil as an R-G-B measurement. Other soil parameters are obtained by correlation with soil color.
