2, 2G - Flaxmere - Dominant Soil @ Map Scale 1:50000
| Associated Soil/s | 21, 56, 4 may also be found within areas (2 & 2g) if a more detailed survey was carried out. |
| Soil Properties of Dominant Soil/s | |
| Parent material | Flaxmere age alluvium from greywacke |
| Characteristics of site | Active flood plain and low terraces adjacent to recent channels, usually protected from flooding by stop banks |
| Soil features | Sand/sandy loam on higher and silt loams on lower parts, both overlying stones |
Natural drainage
Depth to gley and hence to water table after wet periods | Imperfect
30-60cm |
| Potential rooting depth, texture, and limiting layer | 2 – 45–100 cm sand/sandy loam on stones
2g – 30-45 cm sand/sandy loam on stones |
| Available water capacity (AWC) | 2, 50-75 mm
2g, 25-50 mm |
| Infiltration rate | 2, 2g - rapid |
| Permeability rate | 2, 2g - rapid
2 - slow if buried topsoil |
| Susceptibility to pugging and compaction when wet | 2 - moderate
2g - low |
| Susceptibility to wind erosion when dry | 2g - high where topsoil sand |
| Unfavourable soil characteristics | Imperfect drainage
2g - <45cm to gravel
Rapid infiltration
Rapid permeability |
Soil Management of Dominant Soil/s
| Artificial drainage - drain spacing | 60-80m |
| Cultivate when moist to avoid wind erosion | 2g |
Irrigation:-
Recommended method
Dripper spacing for continuous wetted strip
Amount and frequency | Sprinklers to prevent water loss
30-40cm if 4 l/hr drippers used
2g - 10-25mm often to prevent water loss |
