Fundamental Soil Layers
Spatial information for 16 key attributes
Maps of FSLs
Maps show a range of soil attributes derived from the dominant soils depicted in the 1:50 000 scale NZ Fundamental Soil Layers.
Most of the maps show the most likely (i.e. modal) value from the classed soil attribute data. Even within small areas of the same soil, soil attributes can be very variable. You can click on a soil area to see our estimate of the range of values that might be expected for each soil. Since it is quite impractical to measure soil attributes for all soils, we also provide a guide to the technique we used to derive our estimate. These range from 'measured', indicating the the mapped soil has been measured, to 'general inference', indicating the soil measured was generally similar to the mapped soil, but we have no actual measurements to support the inference.
