Format
a large data.frame:
- xcoord
X-coord, Dutch grid (Amersfoort-RD, EPSG:28992)
- ycoord
Y-coord, Dutch grid
- soilclass
Major soil class
- description
soil class description
- sample
Sample code
- compartment
soil compartment, top- or subsoil
- ds
start of sampling depth, relative to surface
- de
end of sampling depth, relative to surface
- pH
soil pH
- om
soil organic matter
- xrf...
XRF measurement
- hf...
HF digested and subsequent ICP-MS measurement
- re...
0.43M HNO3 extraction and subsequent ICP-MS measurement
- reo...
0.43M HNO3 extraction and subsequent ICP-OES measurement
- pw...
0.01M CaCl2 extraction and subsequent ICP-MS measurement
- log....
is value below (<), within (=) or above (>) limit
of quantification
Details
The sampling of the data and the first series of chemical analyses
with the XRF and HF-digestion is given in Van Der Veer (2006),
https://dspace.library.uu.nl/handle/1874/13275
The second series of chemical analyses used two types of different
extractions on the soil samples, i.e. 0.43M HNO3 and 0.01M CaCl2.
Measurements were done with ICP-MS and ICP-OES.
For each analyses the limit of quantification was determined, the
data presents the original concentrations and a seperate field
indicates if the measurement is within the limits of
quantification.
Besides this data.frame, the data.frame atlasmeta gives some
additional meta data.
