“…Although these systems are commonly mounted on trucks or tractors, other systems have been developed that are either manually operated systems (Wells 1959;Hayden and Heinemann 1968;Jackson 1986;Karahashi et al 1987;Prior and Rogers 1994) or use hand-operated power drivers (hammers) and core-extraction systems (winches); these systems tend to be more portable and do not require mechanized vehicles (Prior and Rogers 1992). Commercially available small-diameter steel core tubes have been designed to hold clear plastic liners that hold the actual soil sample; this system facilitates processing and storage of soil samples.…”

A critical objective of belowground research is to collect and process representative soil samples. Mechanical devices have been developed to quickly take soil cores in the field; however, techniques to rapidly process large-diameter soil cores are lacking. Our objective was to design and construct a soil extraction -cutting system that could effectively reduce processing time. Soil cores were extracted from large diameter steel core tubes using a custom hydraulic cylinder device that vertically pushes the soil core to a desired depth increment before cutting in a horizontal direction with another hydraulically driven device. As many as eight large cores per hour could be processed with this system. This system has been effectively used in processing soil samples from both agricultural and forestry sites to meet desired experimental goals.
