The Soil Name and Layer Files contain attribute information for all B.C. named soils and their soil layers as contained in the National Soil DataBase (NSDB). The Soil Name File contains the general physical and chemical characteristics for soils including soil name, soil code, surficial material, water table characteristics, root restricting layer, soil drainage, parent material texture, chemical properties, position in the landscape, mode of deposition, and soil classification. The Soil Layer File contains average or estimated information about the horizons/layers for each soil name. These include upper and lower depths of each layer, coarse fragment, sand, silt and clay content, organic carbon content, pH, Cation Exchange Capacity (CEC), saturated conductivity, water retention, bulk density, electrical conductivity, calcium carbonate equivalent, Von Post and woody Material content. Layer data is based upon real measurements or estimates provided by experienced soil scientists. The Soil Name and Layer Files can be joined and related to each of the 3 components of the Soil Survey Spatial View polygons using the SoilSymbol field in the name and layer tables and the SOILSYM_x fields in the Soil Survey Spatial View.

Additional Information

Purpose

The Soil Name and Layer Files can be used to explore general soil characteristics in BC. The Soil Name and Layer Files can also be joined and related to each of the 3 components of the Soil Survey Spatial View to enables spatial analysis of the generalized soil characteristics.

Data Quality

The Soil Layer File(SLF) data is based upon real measurements where available, but the majority of values are estimates provided by experienced pedologists. The data in the SLF can be considered to represent modal information for each attribute in isolation. As such it is appropriate for mapping and land suitability interpretations. It should not be treated as real pedons (soil horizons at a specific loction) for environmental modelling purposes because the recorded combination of measurements may never actually be present for any pedon in the field. Measurements for real pedons are stored in the BCSIS pedon database. See the Soil_sites dataset.

Lineage Statement

This data is related to the data in the Canadian National Soil DataBase (NSDB) available from: http://sis.agr.gc.ca/cansis/soils/provinces.html .
