Title: AG30SLF: AGRASID 3.0 Soil Layers File
Geospatial_Data_Presentation_Form: tabular digital data
Description:
Abstract:
The AGRASID Soil Layers file (AG30SLF) represents the one to many relationship between a soil name and its associated soil layers. The fields defined in this file were determined to be the minimum data set necessary to interpret a soil specifically for agronomic purposes (CanSIS Manual 3 Procedures and Users Guide revised 1994). AG30SLF links to AG30SNF via the NEW_SYMBOL key field.
Purpose:
The Soil Layer File (AG30SLF) contains information on the chemical and physical properties for each layer (horizon) associated with each soil name listed in the Soil Names File (AG30SNF).

Entity and Attribute Information

Detailed_Description:
Entity_Type:
Entity_Type_Label: AG30SLF
Attribute:
Attribute_Label: NEW_SYMBOL: This field contains a concatenated version of the Soil Name Symbol and Soil Variant variables discussed previously. The NEW_SYMBOL is the key field used to join (or link) to the Alberta Soil Names File AG30SNF.
Attribute:
Attribute_Label: VARIANT: The variant is used to describe soils that are sufficiently different to warrant recognition but do not justify a new soil name due to limited geographic extent. Up to two variants may be associated with a soil name code (Table 4.9 in the AGRASID Version 1.0 Procedures Manual).
Attribute:
Attribute_Label: LU: Land Use - N = Native (Ah horizon) and A = Agricultural (Ap horizon).
Attribute:
Attribute_Label: LAYER_NO: Horizon number.
Attribute:
Attribute_Label: HZN_LIT: Horizon lithological discontinuity.
