Soil Properties

Parent material	Water deposit (alluvium) from greywacke and/or sandstone
Characteristic site and soil features	Active channel, flooding prevented by stopbank; shallow gravelly and stony soils
Associated soils not shown within map unit at map scale but separated out in more detailed maps. - Sample Location	2, 20   N, O
Natural drainage and depth to Water Table after wet periods	Imperfect 0-60cm
Potential rooting depth, texture, and limiting layer	7-15cm sand on stoney gravels
Available water capacity	3.5 - 7mm
Infiltration rate	Rapid
Permeability rate	Very rapid
Susceptibility of topsoil to pugging and compaction when wet	Extremely low
Susceptibility to wind erosion when dry	Very high
Unfavourable soil characteristics	Sand topsoil susceptible to wind erosion many stones at surface very low AWC

 

Soil Management

Artificial drainage: drain spacing	56     none required           However, water table high when river in flood           but drops quickly as river level drops
Cultivate when moist to avoid: wind erosion	56
Irrigation:- recommended method Dripper spacing for continuous wetted Strip Amount and frequency	56     sprinkler to prevent water loss 56     7.5 - 15cm if 4 l/hr drippers used           little (1.5 - 3.5mm), often to prevent water loss
