Select a diagnostic factor to view per-crop tolerance thresholds, Capability cross-reference, and assessment method.
Capability asks whether land can support farming at all. Suitability asks how well one specific crop would do on it. The same measurements are read again — this time against each crop’s own tolerance rather than a general threshold. The class is always set by the single worst factor, never by an average.
s, five share n, five share c. This is a known FAO limitation, handled the same way the Capability and Land Rights & Constraints modules handle it: the subclass letter travels on the map and in summary tables; the specific limiting factor is named in full in the zone record and the attribute table. A result reads S3s on a map, and “S3 — limited by rooting depth” in the location detail.

| Code | Diagnostic factor | This system |
Shift by delivery method | |||
|---|---|---|---|---|---|---|
| Drip | Sprinkler | Centre pivot | Surface / flood | |||
| A · Soil Physical | ||||||
| SQ-A-01 | Available Water Capacitysⓘ | ● | ↓ | ● | ● | ↑ |
Surface applies large volumes infrequently, so the soil must store between irrigations. Drip refills the root zone daily and compensates for low holding capacity. | ||||||
| SQ-A-02 | Soil Workabilitysⓘ | ● | ● | ● | ● | ↑ |
Surface irrigation requires land levelling before the first crop. Workability governs the cost of that operation; the other three methods do not need it. | ||||||
| SQ-A-03 | Rooting Conditionss | ● | ● | ● | ● | ● |
| SQ-A-04 | Surface Sealing & Crustingsⓘ | ● | ↓ | ↑ | ↑ | ↑ |
Sprinkler and pivot droplets strike bare soil and drive crust formation. Drip never wets the surface between emitters. | ||||||
| SQ-A-05 | Soil Texturesⓘ | ● | ↓ | ● | ● | ↑ |
Texture sets the infiltration rate, which determines furrow length and basin size in surface systems. Under drip the emitter rate is set independently of the soil. | ||||||
| SQ-A-06 | Coarse Fragmentssⓘ | ● | ↓ | ● | ↑ | ↑ |
Tower wheels and levelling equipment both suffer on stony ground. Drip lines are laid over it. | ||||||
| B · Soil Chemical | ||||||
| SQ-B-01 | Salinity (ECe)zⓘ | ● | ● | ↑ | ↑ | ↑ |
Sprinkler and pivot wet the foliage, adding a leaf-burn pathway to the root-zone effect. Surface accumulates salt fastest without a controlled leaching fraction. FAO-29 sets stricter limits for overhead application. | ||||||
| SQ-B-02 | Sodicity (ESP / SAR)zⓘ | ● | ↓ | ● | ● | ↑ |
Sodium collapses infiltration. That is fatal to surface irrigation, which depends on water moving across and into the profile; drip delivers under pressure to a point. | ||||||
| SQ-B-04 | Toxicity Risk (Boron)nⓘ | ● | ● | ● | ● | ● |
Boron is taken up through the root regardless of delivery method. | ||||||
| SQ-B-05 | Calcium Carbonaten | ● | ● | ● | ● | ● |
| SQ-B-06 | Gypsum Contentnⓘ | ● | ● | ● | ● | ↑ |
Gypsum dissolves and can destabilise levelled basins and channels. | ||||||
| SQ-B-07 | Soil pHn | ● | ● | ● | ● | ● |
| C · Water & Drainage | ||||||
| SQ-C-01 | Drainage Conditionwⓘ | ● | ● | ● | ● | ↑ |
Surface irrigation applies large volumes at once. Without free drainage the root zone stays saturated far longer than under any pressurised method. | ||||||
| SQ-C-02 | Flood Hazardf | ● | ● | ● | ● | ● |
| SQ-C-03 | Waterlogging Riskwⓘ | ● | ↓ | ● | ● | ↑ |
Same reason as drainage — application volume per event drives the risk. | ||||||
| D · Topography & Erosion | ||||||
| SQ-D-01 | Terrain Workabilitytⓘ | ● | ↓ | ● | ↑ | ↑ |
The primary differentiator. Drip works on ground no other method can cross. Pivot towers must traverse the whole circle. Surface needs near-level ground and governs hardest of the four. | ||||||
| SQ-D-02 | Water Erosion Hazardeⓘ | ● | ↓ | ↑ | ↑ | ↑ |
Overhead droplet energy and surface flow both detach soil. Drip does neither. | ||||||
| SQ-D-03 | Wind Erosion Hazardeⓘ | ● | ● | ↑ | ↑ | ● |
Wind distorts sprinkler and pivot distribution uniformity as well as eroding soil — a compounding effect no current element captures. | ||||||
| SQ-D-04 | Sand Encroachment Hazarddⓘ | ● | ↑ | ● | ↑ | ● |
Emitters clog with wind-blown fines; pivot towers suffer mechanical damage from drifting sand. | ||||||
| E · Climate | ||||||
| SQ-E-01 | Moisture Deficit (Aridity)c | ▲ | ● | ● | ● | ● |
| SQ-E-02 | Thermal Suitabilityc | ● | ● | ● | ● | ● |
| SQ-E-03 | Radiation & Solar Energyc | ● | ● | ● | ● | ● |
| SQ-E-04 | Length of Growing Period (LGP)c | ▲ | ● | ● | ● | ● |
| SQ-E-05 | Frost Riskcⓘ | ● | ● | ◖ | ◖ | ● |
Inverted. Sprinkler and pivot systems are deliberately run during radiation frost — the latent heat released as water freezes on the plant holds tissue near 0 °C. Frost risk becomes a capability the method provides, not a limitation. | ||||||
| F · Crop-Specific | ||||||
| SQ-F-01 | Irrigation Demand (ETc)iⓘ | ● | ↓ | ● | ● | ↑ |
Application efficiency differs sharply: drip is the highest of the four, surface the lowest. The same crop demand becomes a different abstraction requirement. | ||||||
| SQ-F-02 | Crop Nutrient Requirementnⓘ | ● | ↓ | ● | ● | ↑ |
Fertigation through drip places nutrients in the wetted zone. Surface systems broadcast, and losses on a calcareous soil are higher. | ||||||
