Description :
The quantification of element pools and their changes in time is an important part of the analysis of ecosystems. This quantification is more difficult in soils with rock fragments. Repeated sampling and geostatistical analysis were used to quantify spatial heterogeneity in rock fragment content. Cs 137 measurements were used to quantify fine-earth contamination of dry-sieved and washed rock fragments because they are nondestructive and allowed for repeated analysis of the same sample. The Cs 137 technique therefore allows an easy and less laborious estimation of the part of other element pools associated with rock fragments than direct measurements.
