A RAPID PROCEDURE FOR SECURING LARGE UNDISTURBED SOIL CORES

A METHOD IS DESCRIBED FOR RAPIDLY OBTAINING LARGE, UNDISTURBED SOIL CORES RANGING FROM 16 TO 38 INCHES IN DIAMETER AND TO DEPTHS OF UP TO 9 FEET. SUCH CORES IN SOME CASES CONTAINING SEVERAL THOUSAND POUNDS OF SOIL, MAY BE USED IN PLACE OR MOVED TO A CONTROLLED ENVIRONMENT FOR A NUMBER OF PURPOSES, EG., STUDIES OF TRANSPIRATION, EVAPOTRANSPIRATION, MOISTURE FLOW, AND OTHERS. IN SUCH CASES DISTURBED SOIL MATERIALS OFTEN ARE NOT SATISFACTORY BECAUSE OF THE INFLUENCE OF DISTURBING THE SOIL ON SUCH PROPERTIES AS MOISTURE TRANSMISSION, MOISTURE RETENTION, AND ROOT DISTRIBUTION. /RRL/A/
