| Indicator | Threshold level | Threshold formulae |
| Soil depth (X1) | 50 cm or the community’s average of similar soil types, whichever is greater | mean X1 or 50 cm, whichever is greater |
| Organic carbon (X2) | 1% or the community’s average, whichever is greater | 1.0 when mean X2 < 1.0, mean of X2 otherwise |
| Water stable aggregates (X3) | Average of land use at the site | mean X3 |
| Bulk density (X4) | Average of land use at the site | mean X4 |
