AGRASID 4.1 and LSRS: Alberta Soil and the Productivity Score
AGRASID 4.1 is Alberta's soil information database and the source of the LSRS productivity score. Township Canada carries soil detail and the 0-100 score per quarter section.
What it is
AGRASID 4.1 (the Agricultural Region of Alberta Soil Inventory Database) is the province's authoritative soil-polygon dataset. It is also the source of the Land Suitability Rating System (LSRS) productivity score, the federal-provincial standard for rating dryland spring-cereal cropland on a 0-100 scale. In Alberta, Township Canada reads the LSRS score directly from AGRASID.
What it carries
AGRASID contributes the soil subgroup, drainage, parent material, slope, and salinity for each polygon. LSRS contributes the productivity score and the single limiter capping it - climate, moisture, soil, water, continuous cropping, or pattern. The score is reported per quarter section with its limiter.
Coverage and refresh
We carry an LSRS productivity score on more than 380,000 Alberta quarter sections, refreshed annually each June. Outside Alberta, the Soil Landscapes of Canada fallback supplies the soil context.

How Township Canada shows it
AGRASID and LSRS power the Ag Summary map layer (Agriculture Bundle), themed by productivity class, and the soil and productivity cards on the Agriculture tab of the parcel report. The LSRS score is the soil component (50% weight) of the composite Productivity Score.
