Saskatchewan soil classes explained

Every located listing on SaskTaxSales shows a soil class — the Canada Land Inventory (CLI) agricultural-capability rating read from Saskatchewan's public soil survey. It's the honest, free way to judge the quality of a parcel's land when no assessed value is available. Here's what the classes mean.

The 1-to-7 capability scale

CLI rates land from Class 1 (the best cropland) to Class 7 (no agricultural capability). The higher the number, the more limited the land is for farming:

• Class 1 — no significant limitations. The best cropland: deep, well-drained, productive soil.
• Class 2 — minor limitations. Good cropland with slight constraints (a little dry, mild slope).
• Class 3 — moderate limitations. Fair cropland that needs careful management.
• Class 4 — severe limitations. Marginal for crops; often better as hay or pasture with the occasional crop.
• Class 5 — very severe limitations. Improved pasture or perennial forage only, not reliable cropland.
• Class 6 — natural grazing only. Native pasture; not arable.
• Class 7 — no agricultural capability. Not suited to farming (rock, water, badly eroded or saline).

A quick rule of thumb: Class 1–3 is genuine cropland, Class 4 is marginal, and Class 5–7 is grazing or non-farm land.

Why a listing shows a blend ("80% Class 2, 20% Class 4")

A parcel rarely has one uniform soil, so the survey maps it as a composition — the proportion of each class within the parcel. We show the dominant class as the headline and the full mix in the bar and legend, so you can tell whether a "Class 3" parcel is mostly good ground with a poor corner or an even split.

What the "main limit" means

Each class carries a limitation that explains why the land is constrained. The common ones in Saskatchewan:

• Droughty (low moisture) — the soil doesn't hold enough water for reliable crops.
• Excess water — poorly drained, wet, or prone to ponding.
• Low fertility — inherently poor nutrients.
• Salinity — salts that reduce yield (shown as a separate salinity reading too).
• Stoniness, structure, topography, erosion — physical constraints on working the land.

Salinity and distance to water

Alongside the class, a listing shows a salinity reading (nonsaline is good; moderate or higher cuts yield) and, where relevant, how close the parcel sits to mapped water. Together they give a fuller picture than the class alone.

Where the number comes from — and its limits

The class is read straight from Saskatchewan's public Canada Land Inventory soil survey at the parcel's location. It is a regional guide, not a soil test on your parcel — an excellent starting point, but confirm on the ground before you bid. The survey also only covers agricultural southern Saskatchewan; northern (boreal/Shield) parcels have no soil rating, which is why some listings show none.
