Find Top-LSRS Farmland in Alberta: Mapping Soil Productivity for Acquisition
Use the LSRS overlay to scan whole RMs for top-rated soil. For investors and large operators scoping acquisition pipelines.
Find Top-LSRS Farmland in Alberta
For investors and large-farm acquisition teams, scanning soil productivity at scale is the first filter before any deal sheet gets built. The Township Canada LSRS layer lets you toggle a colour-coded overlay across an entire RM, county, or polygon-drawn search area, then drill into individual parcels.
The two-step workflow
Step 1 — Toggle the LSRS overlay. From the data catalog, turn on "LSRS Productivity (AB)." The map fills in with the colour ramp:
| Range | Colour | Label |
|---|---|---|
| 81-100 | Deep blue | Excellent |
| 61-80 | Light blue | Good |
| 41-60 | Yellow | Fair |
| 21-40 | Orange | Poor |
| 0-20 | Red | Very poor / unsuitable |
Top-LSRS ground in Alberta is concentrated in the Black Soil Zone — the band running roughly Camrose-Lacombe-Olds. The Brown Soil Zone (Hanna, Brooks, Medicine Hat) is mostly class 3-5 for spring cereals; in those areas, irrigation history matters more than the base LSRS.
Step 2 — Draw a search polygon (Ag Investor only). From /app/territory, draw a polygon over the area you're interested in. The Territory & Prospecting tool returns every parcel inside, sorted by LSRS productivity. From there:
- Filter to class-1 or class-2 parcels only
- Export to CSV with Salesforce/HubSpot column mapping
- Cross-reference with the AAFC crop history (canola-heavy rotation suggests confirmed-productive ground vs. recently-broken)
Combining LSRS with crop history
LSRS scores intrinsic suitability. AAFC crop history shows what was actually grown. A class-1 quarter that's been in canola for five straight years is high-confidence productive ground — the LSRS suitability claim is validated by the rotation history. A class-1 quarter in fallow for three of the last five years tells a different story (irrigation? lease issue? owner-operator constraints?).
The territory CSV export includes both columns, so the filter logic is straightforward to apply downstream.
Coverage notes
- LSRS is Alberta v1 only. Saskatchewan coverage is in flight (compute from AGRASID + SKSIS + climate + DEM). Manitoba, BC, Ontario are further out.
- LSRS for spring-seeded small grains. Pasture and oilseed-specific variants exist in AAFC's published outputs but aren't currently in the Township Canada catalog.
- The CSV export caps at 5000 parcels per query — RMs larger than that should be split into sub-polygons.
What this is NOT a substitute for
- Soil tests on the specific parcel. LSRS is a regional-scale rating; a 160-acre quarter with internal variability still benefits from a current soil test before bidding.
- Recent ownership history. LSRS doesn't update for active erosion or recent practice changes; the AAFC crop history surfaces what actually grew but doesn't tell you about cover crops or tillage.
