76 - Horoeka - Dominant Soil @ Map Scale 1:50000

Associated Soil/s	75, 32  may also be found within this area (76)  if a more detailed survey was carried out.
Soil Properties of Dominant Soil/s
Parent material	Tikokino age alluvium from the erosion of Castlecliffian deposits (layers of sandstone, siltstone, mudstone and greywacke stones) over loess alluvium on red metal
Characteristics of site	Gently sloping intermediate terraces
Soil features	Silt loams over clay on stony silt loam over cemented pan
Natural drainage Depth to perched gley	Imperfect Water perched at 30-60 cm on clay pan
Potential rooting depth, texture, and limiting layer	30 cm silt loam on gleyed silt loam on clay pan 45-60 cm on stony sandy loam at 75-85 cm on cemented pan at <100 cm
Available water capacity	75-100 mm
Infiltration rate	Moderate
Permeability rate	Slow
Susceptibility to pugging and compaction when wet	High
Susceptibility to wind erosion when dry	Low
Unfavourable soil characteristics	Imperfect drainage, water perched on clay pan at 45-60 cm Slow permeability Topsoil easily compacted causing slow infiltration

 

Soil Management of Dominant Soil/s

Artificial drainage	Mole drains
Cultivate when moist to avoid compaction	76
Irrigation:- Recommended method Dripper spacing for continuous wetted strip Amount and frequency	Sprinkler to prevent waterlogging 50 cm 25-35 mm often to prevent waterlogging
