1.1 ,This practice uses a technique of probing to estimate the thickness of surficial peat deposits overlying mineral soil or bedrock.
1.1.1 ,The resistance to penetration of a pushed or driven rod will increase sharply at the boundary of a peat layer with underlying mineral soil or bedrock. When this abrupt change is measured in a series of probings with an appropriate spacing, the thickness and areal extent of peat can be defined and the volume of peat may be calculated.
