LUC Description
1 Suitable for crops. Most versatile multiple-use land.
2 Slight limitations for crops. Good versatile land.
3 Moderate limitations for crops.
4 Severe limitations for cropping or cultivation. More suited to specific crops, permanent pasture or forestry.
5 Unsuitable for cropping. Negligible limitations to pasture, grapevines, tree crop, or forestry.
6 Productive pastoral hill country, slight to moderate limitations or hazards to pasture, tree crops, and/or forestry.
7 Severe to very severe limitations or hazards for grazing with intensive soil conservation measures, more suited to forestry
8 Very severe to extreme limitations, requiring permanent vegetative cover and protection, unsuitable for agriculture.

Erosion (e) is significant to the capability of the whenua, because if the soil is permanently lost through erosion the whenua will take many years to develop new soil.
Wetness (w) that can present an issue to land capability include: waterlogging due to a rising water table in wet periods, perching of water above a layer preventing water moving through it and flooding.
Soil (s) limitation can be due to shallow soil, stones, rock outcrops, subsurface pans in the soil leading to a low soil water holding capacity, or a low fertility/trace element deficiency or a chemical toxicity.
Climate (c) limitations include the number of growing degree days, first and last frost timing, average rainfall, evapotranspiration rates and rainfall distribution, exposure to damaging and salt-laden winds.

Land Cover

Land Cover Area (ha) Percentage
Indigenous forest 368.3 65.8%
Production forest 176.5 31.5%
Tall tussock grassland 14.9 2.7%
High producing exotic grassland 0 0%
Land cover is the classification of what is covering the lands surface. Generally this will be vegetation classes. Land cover may often imply something about land use but this is not certain.

Soil Properties

Profile Readily Available Water

Description Area (ha) Percentage
Moderately High 535.3 95.7%
Unclassified 23.8 4.3%
Profile readily available water is a classification of profile readily available water for the soil profile to a depth of 0.9 m, or to the potential rooting depth (whichever is the lesser).

Potential Rooting Depth

Description Area (ha) Percentage
Very deep 303.7 54.3%
Deep 231.6 41.4%
Unclassified 23.8 4.3%
Potential rooting depth describes the depths to a layer that may impede root extension. This may be due to penetration resistance, poor aeration or low available water capacity.


Description Area (ha) Percentage
Well Drained 535.8 100%
Soil drainage is a classification of the extent to which a subsoil is waterlogged during an average year. Soil drainage is important for the supply of oxygen to the plant root zone, waterlogging, and water drainage.

Particle Size

Description Area (ha) Percentage
Unclassified 435.9 78%
Loamy 122.8 22%
Silty 0.5 0.1%
The proportions of sand, silt and clay in the fine earth fraction of the soil except in the case of skeletal soils.

Rock Outcrops and Surface Boulders

Description Area (ha) Percentage
Not rocky 303.7 54.3%
Slightly rocky 231.6 41.4%
Unclassified 23.8 4.3%
The percentage of the area covered by rock outcrops or surface boulders.

Phosphate Retention

Description Area (ha) Percentage
Medium 354.9 63.5%
High 180.5 32.3%
Unclassified 23.8 4.3%
Phosphorus is a key nutrient for the successful growth of crops and pastures.

Depth to Slowly Permeable Horizon

Description Area (ha) Percentage
Deep (0.6 - 0.89m) 535.3 95.7%
Unclassified 23.8 4.3%
Depth to a slowly permeable horizon describes the minimum and maximum depths (in metres) to a horizon in which the permeability is less than 4mm/hr as measured by techniques outlined in Griffiths (1985).
