Constructing a soil monolith requires an undisturbed soil profile sample that can be easily mounted and displayed. The collection of profile samples from' pits or road cuts by traditional methods is time consuming and often expensive. An alternative solution was developed to collect the profile samples using a hydraulic probe fitted with a core tube having an inside diameter of 6.9 cm (2.7 in). The soil core is mounted on 7.6 cm (3 in) diameter plastic polyvinyl chloride (PVC) pipe that has been split longitudinally. Excess soil is removed from the core and the sample is treated with a vinyl fixative solution. The treated core is mounted on a plywood display board that contains classification, site, location, and horizonation information about the soil. Monoliths prepared using this procedure are easy to construct, durable, less expensive, attractive, large enough to show soil properties clearly, and they are comparable to those gathered by traditional methods.
