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
