soil map units where Af WW2 Air Field is dominant
Soil properties
| Property | Value |
|---|---|
| Geographic distribution | Tuvalu |
| Landscape position | WW2 Airfield areas on Nukufeatau and Nanumea that occur mainly inland along the long axis of a motu, but usually with one or more cross runways. |
| Soil parent material | Coralline gravel |
| Slope | Flat (0-3°) |
| Surface outcrops | No surface outcrops |
| Brief soil profile description | Anthopically altered and compacted surfaces of coral gravel that were not broken up so only minimal soil development has occurred on the hardpan surfaces. |
| Soil profile texture | - |
| Minimum effective rooting depth | n/a |
| Soil pH (acidity) | - |
| Salinity | n/a |
| Soil fertility under natural conditions | Not analysed |
| Soil moisture regime | - |
| Susceptibility to drought | Compacted surface of coral gravel likely to be prone to drought during dry periods |
| Soil drainage | - |
| Susceptibility to waterlogging | Not susceptible |
| Susceptibility to flooding | Typically not susceptible to flooding |
