| Title | Soil salinity rating (SK) |
| Description | Soil salinity rating for entire soil polygon. A salinity rating that consists of a single numeric character indicates that it is a derived rating (not field mapped) and shows extent only; salinity degree for such ratings is considered moderate (4 - 8 dS/m). |
| Classes | Salinity symbol (SK). Up to 4 columns. |
| Code | Class | Description |
|---|---|---|
| 0 | 0% of polygon affected | |
| 1 | 0 - 3% of polygon affected | |
| 2 | 3 - 10% of polygon affected | |
| 3 | 10 - 20% of polygon affected | |
| 4 | 20 - 40% of polygon affected | |
| 5 | 40 - 70% of polygon affected | |
| 6 | >70% of polygon affected |
| Code | Class | Description |
|---|---|---|
| 0 | Nonsaline | Nonsaline (0 - 2 dS/m) |
| W | Weakly saline | Weakly saline (2 - 4 dS/m) |
| M | Moderately saline | Moderately saline (4 - 8 dS/m) |
| S | Strongly saline | Strongly saline (8 - 16 dS/m) |
| V | Very strongly saline | Very strongly saline (>16 dS/m) |
| Code | Class | Description |
|---|---|---|
| S | Saline sides of hills | Saline soils occur on the sides of hills and slopes well above any slough or depression. |
| P | Saline edges of depressions | Saline soils occur on the edges of depressions, sloughs or runways. All soils in the bottoms of depressions are leached and nonsaline. |
| I | Saline upper slopes | Saline soil parent materials within 60 cm of the soil surface generally occur on knolls and upper slopes. |
| D | Saline dissections | Saline soils occur throughout bottoms of dissections and small runways. |
| A | Saline depressions | Saline soils occur throughout bottoms of depressions and sloughs. |
