ABSTRACT:
An intact core sample from a soil area, such as a golf green or a ball field, is embedded in molded plastic. The core sample first is obtained, and then adhesively bonded together prior to molding it in clear plastic to preserve the soil core sample in an intact and durable fashion for subsequent visual examination of the composition of the soil core sample.
