Soil Properties
| Parent material | Water deposit (alluvium) from greywacke and/or sandstone |
| Characteristic site and soil features | Active channel, flooding prevented by stopbank; shallow gravelly and stony soils |
| Associated soils not shown within map unit at map scale but separated out in more detailed maps. - Sample Location | 2, 20
N, O |
| Natural drainage and depth to Water Table after wet periods | Imperfect
0-60cm |
| Potential rooting depth, texture, and limiting layer | 7-15cm sand on stoney gravels |
| Available water capacity | 3.5 - 7mm |
| Infiltration rate | Rapid |
| Permeability rate | Very rapid |
| Susceptibility of topsoil to pugging and compaction when wet | Extremely low |
| Susceptibility to wind erosion when dry | Very high |
| Unfavourable soil characteristics | Sand topsoil susceptible to wind erosion many stones at surface
very low AWC |
Soil Management
| Artificial drainage: drain spacing | 56 none required
However, water table high when river in flood
but drops quickly as river level drops |
Cultivate when moist to avoid:
wind erosion | 56 |
| Irrigation:- recommended method
Dripper spacing for continuous wetted Strip
Amount and frequency | 56 sprinkler to prevent water loss
56 7.5 - 15cm if 4 l/hr drippers used
little (1.5 - 3.5mm), often to prevent water loss |
