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:

RangeColourLabel
81-100Deep blueExcellent
61-80Light blueGood
41-60YellowFair
21-40OrangePoor
0-20RedVery 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.
