Soil Properties

 

Parent material	Water deposit (alluvium) of Tutaekuri from greywacke and/or sandstone on lagoon deposits
Characteristic site and soil features	low lying areas on margins of old lagoon which was covered by water in floods and high tides before the 1931 earthquake; silty and clayey alluvium on shelly  lagoon sediments
Associated soils not shown within map unit at map scale but separated out in more detailed maps. - Sample Location	23, 24, 25   M
Natural drainage and depth to gley and hence to water table after wet periods	26      poor - <30cm 27      very poor to poor - 0-30
Potential rooting depth, texture, and limiting layer	26      >45cm silt loam on shelly sandy loam 27      30-45cm clay loam on shelly silt loam
Available water capacity	26      75-100mm 27      35-50mm
Infiltration rate	26      moderate 27      slow
Permeability rate	26,27 slow
Susceptibility of topsoil to pugging and compaction when wet	26      very high 27      extremely high
Unfavourable soil characteristics	26      slowly permeable lagoon sediments free lime,             high pH (alkaline)            saline  27      as above but heavy topsoil easily compacted and           difficult to manage in wet conditions           slow infiltration           shallow clay loam to shelly sediment

 

Soil Management

Artificial drainage: drain spacing	26, 27 10 - 20m
Cultivate when moist to avoid: compaction	26, 27
Irrigation:- Recommended method application rate Dripper spacing for continuous wetted strip Amount and frequency	26, 27   sprinkler to prevent waterlogging 27          slow <4mm/hr if 4 l/hr drippers used 26          60cm 27          70cm27 little (15-25mm), often to prevent                waterlogging
