The map shows the location of each National Soil Inventory of Scotland sampling point. The colour of the symbol relates to the zinc concentration of the topsoil found at that point (in parts per million of air-dried soil). The soils were sampled between 1978 and 1988 as part of the National Soil Inventory of Scotland.
The Zinc (Zn) concentration (parts per million of air-dried soil) is shown in the following categories:
|Zn concentration less than 8.1 ppm|
|Zn concentration between 8.1 and 19.8 ppm|
|Zn concentration between 19.8 and 35.6 ppm|
|Zn concentration between 35.6 and 56.6 ppm|
|Zn concentration between 56.6 and 96.8 ppm|
|Zn concentration greater than 96.8 ppm|
Zinc (Zn) concentration in the topsoil is reported in parts per million (ppm) of air dried soil from the National Soil Inventory of Scotland (NSIS 1978-88) dataset. Data was collected at sample locations arranged on a 10 km grid across the country. The map shows the location of each sampling point and the zinc concentration of the topsoil.
You can find out more about the protocols used to generate this map can in the NSIS Soil location, sampling and profile description protocols and the Geochemical atlas for Scottish topsoils.
