A Technique for Obtaining Undisturbed Soil Samples by Freezing in Situ
1968
Blevins, R. L. | Aubertin, G. M. | Holowaychuk, N.
A freezing technique employing liquid nitrogen has been developed to freeze soil blocks in situ. This technique makes it possible to collect undisturbed samples from soils that are incoherent, have an abundance of roots or have a high percentage of coarse skeletal materials. The frozen blocks can be transported to the laboratory in a frozen state and eut into desired-size blocks for bulk density, moisture retention and micromorphological studies.
