Soil Properties

Parent material	Water deposit (alluvium) of hill streams from limestone and greywacke
Characteristic site and soil features	Narrow terraces on the sides of hill streams from the Havelock and other hills on the southern boundary; soils are alkaline with bits of limestone. The textures varying with the type of limestone - sandy loams from sandy limestone and clay loams from clayey limestone
Associated soils not shown within map unit at map scale but separated out in more detailed maps. - Sample Location	11, 32   B
Natural drainage and depth to gley and hence to water table after wet periods	12,    good,  - >60cm 12h,  imperfect - 30-60
Potential rooting depth, texture, and limiting layer	12,   >45cm sandy loam from sandy limestone 12h, >45cm clay loam from clayey limestone
Available water capacity (AWC)	12,    50-75mm  12h, 50-75mm
Infiltration rate	12,    moderate 12h,  if compacted - slow
Permeability rate	12,    moderate 12h,  slow
Susceptibility of topsoil to pugging and compaction	12,    moderate 12h,  very high
Unfavourable soil characteristics	12,   pieces of limestone in topsoil          high pH (alkaline) 12h, heavy topsoil - easily compacted          slow infiltration          subsoil of slow permeability          free lime present - high pH (alkaline)

 

Soil Management

Artificial drainage: drain spacing	12,   none required 12h, 20-40m
Cultivate when moist to avoid: compaction	12h
Irrigation:- Recommended method application rate Dripper spacing for continuous wetted strip Amount and frequency	12h,  sprinkler to prevent waterlogging 12h,  slow <4mm/hr if 4 l/hr drippers used 12,     40cm 12h,   60cm
