    Abstract: A soil mapping system for collecting and mapping soil reflectance data in a field includes an implement having a furrow opener for creating a furrow and an optical module. The optical module is arranged to collect soil reflectance data at a predetermined depth within the furrow as the implement traverses a field. The optical module includes two monochromatic light sources, a window arranged to press against the soil, and a photodiode for receiving light reflected back from the soil through the window. The two light sources have different wavelengths and are modulated at different frequencies. The photodiode provides a modulated voltage output signal that contains reflectance data from both of the light sources. Additional measurement devices are carried by the implement for collecting additional soil property data, such as electrical conductivity, pH, and elevation, which can be used together with the optical data to determine variations in soil organic matter.

    Abstract: A system for measuring soil properties on-the-go using a narrow profile sensor unit is provided on an implement for traversing a field. The sensor unit includes a front disk/coulter arranged to open a slot in the soil, a runner assembly arranged to follow behind the front disk/coulter for sliding contact with the soil in the slot, and a rotating disk/spoked wheel arranged to follow behind the runner assembly to close the slot. The front disk or coulter serves as a first electrode of an electrode array, the runner assembly has second and third electrodes attached thereto, and the rotating disk/spoked wheel serves as a fourth electrode. The electrode array can be used to measure soil electrical conductivity at multiple depths and to measure soil moisture. An optical window and pH sensor can also be incorporated into the runner assembly to measure soil reflectance and soil pH.
