The New Zealand Fundamental Soil Layer originates from a relational join of features from two databases: the New Zealand Land Resource Inventory (NZLRI), and the National Soils Database (NSD). The NZLRI is a national polygon database of physical land resource information, including a soil unit. Soil is one in an inventory of five physical factors (including rock, slope, erosion, and vegetation) delineated by physiographic polygons at approximately 1:50,000 scale. The NSD is a point database of soil physical, chemical, and mineralological characteristics for over 1500 soil profiles nationally. A relational join between the NZLRI dominant soil and derivative tables from the NSD was the means by which 14 important soil attributes were attached to the NZLRI polygons. Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layer contains best available data (as at 2000) for soil salinity which is measured as percent soluble salts (g/100g soil). High salinity is detrimental effects on plant growth and yield, can reduce water quality and soil erosion. Salinity is an important land degradation problem.

The New Zealand Fundamental Soil Layer originates from a relational join of features from two databases: the New Zealand Land Resource Inventory (NZLRI), and the National Soils Database (NSD). The NZLRI is a national polygon database of physical land resource information, including a soil unit. Soil is one in an inventory of five physical factors (including rock, slope, erosion, and vegetation) delineated by physiographic polygons at approximately 1:50,000 scale. The NSD is a point database of soil physical, chemical, and mineralogical characteristics for over 1500 soil profiles nationally. A relational join between the NZLRI dominant soil and derivative tables from the NSD was the means by which 14 important soil attributes were attached to the NZLRI polygons. Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layer contains depth to slowly permeable horizon attributes. 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). If no slowly permeable horizon is observed, the taxon is allocated to Class 6 and a null value with numeric code -.99 is entered into the data fields. These classes, described more fully in Webb and Wilson (1995).

Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layer contains potential rooting depth attributes. Potential rooting depth describes the minimum and maximum depths (in metres) to a layer that may impede root extension. Such a layer may be defined by penetration resistance, poor aeration or very low available water capacity. These classes are described more fully in Webb and Wilson (1995).

Chemical limitations to plant growth data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).

This data layer defines three classes of soil based on factors that lead to the accumulation of chemicals that limit plant growth. Classes were differentiated either by their parent material or by their position in the New Zealand Soil Classification. Three classes of chemical limitations, Low (1), Moderate (2) and High (3). The class defined as "0" signifies areas where there are no soil attributes recorded (i.e. high peaks of the Southern Alps).

Additional details such as discussion about the accuracy and reliability of the LENZ soil layers and the technical definitions of the categories in this layer are defined in the attached LENZ Technical Guide.

Soil Map of part of Wallace County

07 Apr 2015

This dataset was first added to LRIS Portal on 07 Apr 2015.

The soil inventory survey of Wallace County, Southland was mapped at 1:50,000 scale and covers approximately 700,000 hectares of a total of 965,600 hectares. Within 6 physiographic regions, soils have been separated by differences in morphology, drainage and parent materials into 132 soil mapping units. Soils have been correlated to South Island soil sets and classification of soils for land use are provided in the attribute table.

This 1986 soil survey has been superceded in lowland areas by Topoclimate South (1998-2001) and S-map (2014) data.

This layer contains best available data as at 2000 for total carbon (organic matter content) which is estimated as weighted averages for the upper part of the soil profile from 0-0.2 m depth, and expressed as a percentage.

There has been a change in the way the S-map is being made available to users. The S-map primary map layer ofsoil classes (i.e. delineated areas that are labelled with the soil family name) is no longer freely available to commercial users. Access to this data and associated soil attribute data for commercial use is by negotiation - please contact Graeme Anderson. This layer is a "dissolved" representation of the soil drainageattribute for S-map previously available as a lookup table.It is available for non-commercial use under a creative commons licence (CC-BY-NC-ND).Soil drainage is a relatively simple classification of the soil profile that describes the likelihood of seasonal wetness. It is based on the occurrence within specific depths of redox segregation and low chroma colours indicative of waterlogging and reduction (Webb and Lilburne, 2011).Very poorly drainedPoorly drainedImperfectly drainedModerately well drainedWell drainedWebb TH, Lilburne LR 2011.
