LENZ - Soil drainage

Added
28 May 2010

This dataset was first added to LRIS Portal on 28 May 2010.

Drainage 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 described the internal drainage of soils. The classification used in the creation of this layer was developed as part of the diagnostic features used in conjunction with the New Zealand Soil Classification, and was defined in terms of the soil attributes that develop under different drainage conditions. Five classes of drainage, ranging from Very Poor (1) through to Good/Well drained (5). 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.

LENZ - Chemical limitations to plant growth

30 May 2010

This dataset was first added to LRIS Portal on 30 May 2010.

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.

LENZ - Soil age

Added
28 May 2010

This dataset was first added to LRIS Portal on 28 May 2010.

Soil age 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 is a classification of two broad soil age classes based on their membership in the New Zealand Soil Classification. This layer describes soil age using morphological features associated with soil development rather than criteria based on chronological ages. As a consequence, soils classified as recent in dry cool environment may be much older than recent soils from warm, wet environments. Only two classes of soil age, Younger (1) and Older (2). 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.

LENZ - Acid soluble phosphorous

Added
27 May 2010

This dataset was first added to LRIS Portal on 27 May 2010.

Acid soluble phosphorous 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 is a measure of how much acid soluble phosphorous is held within the soil. The data defines the level of acid soluble phosphorous based on the soil information (from the NZLRI) and the mapped parent material. This acid soluble phosphorous data layer is differentiated into five classes, ranging from Very low (Class 1) through to Very high (5). 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.

LENZ - Exchangeable calcium

This dataset was first added to LRIS Portal on 30 May 2010.

Exchangeable calcium 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 is a measure of how much exchangeable calcium is held within the soil. The amount of exchangeable calcium defined in the data layer is derived by the soil information (from the NZLRI) and the mapped parent material. Four classes of exchangeable calcium, ranging from Low (1), through to Very High (4). The class defined as "0" signifies areas where there are no soil attributes recorded (i.e. high peaks of the Southern Alps).

Soil map unit raster classification - generated from a Random Forest model based on soil auger data points and terrain and parent material co-variate layers. This model uses 16 soil map units which represent groupings of taxonomically similar soils at NZ Soil Classification sub-group to family level. Random Forest predicts classifications - the map units so defined will be assigned typical soil associations and properties

This dataset contains 500 augers observations of soil properties collected for a digital soil mapping and land use capability analysis in the Kaikohe to Paihia area. An additional 172 tacit points of estimated soil properties at sites where pedologists were confident they could predict likely soil distribution are also included.

These data were used in conjunction with elevation, slope and other spatial explicit covariate data to predict soil distributions continuously across 100 km2 of Northland hill country
