14, 14G - Hastings - Dominant Soil @ Map Scale 1:50000
| Associated Soil/s | 6, 5, 19 may also be found within these areas (14, 14g) if a more detailed survey was carried out. |
| Soil Properties of Dominant Soil/s | |
| Parent material | Hastings age alluvium from greywacke |
| Characteristics of site | Lower flood plain between 5 on levee and 19 in back swamp |
| Soil features | Greywacke alluvium (sandy loams to silt loams) |
Natural drainage
Depth to gley and hence to water table after wet periods | Imperfect
30-60 cm |
| Potential rooting depth, texture, and limiting layer | 14 - >45 cm silt loam on sandy loam/sand
14g – 30–45 cm sandy loam on stones |
| Available water capacity | 14 – 75–100 mm
14g – 35–50 mm |
| Infiltration rate | If not compacted - moderate
If compacted – slow |
| Permeability rate | 14 – Moderate but slow if buried topsoil
14g – moderately rapid |
| Susceptibility to pugging and compaction when wet | High |
| Susceptibility to wind erosion when dry | Low |
| Unfavourable soil characteristics | Imperfect drainage
14 - topsoil easily compacted, causing slow infiltration
14g – moderately rapid permeability |
Soil Management of Dominant Soil/s
| Artificial drainage - drain spacing | 40m |
| Cultivate when moist to avoid compaction | 14 |
Irrigation:-
Recommended method
Dripper spacing for continuous wetted strip
Amount and frequency | Sprinkler to prevent water logging
14 – 60 cm
14g – 40 cm
14 – 35-50 mm
14g – 15–25 mm often to prevent water loss |
