LENZ - Soil particle size

Added
27 May 2010

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

Particle size 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).

The data defines the average particle size based on the soil information (from the NZLRI) and the mapped parent material. This particle size data layer is differentiated into five classes, silt and clay (Class 1), Sand (2), Gravel (3), Coarse to very coarse gravel (4), Boulders to massive (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 - Induration (Soil Hardness)

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

Induration 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).

Induration is a measure of how hard the soil is and is quantified by how much force is needed to break the soil. The data defines the induration based on the soil information (from the NZLRI) and the mapped parent material. This induration data layer is differentiated into five classes, Non-indurated (Class 1), Very weakly indurated (2), Weakly indurated (3), Strongly indurated (4), Very strongly (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.

This dataset was first added to LRIS Portal on 04 Jun 2010.

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 layers contains flood return interval attributes. The classes originate from and are 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 the particle size classification attribute. Particle size class describes in broad terms the proportions of sand, silt and clay in the fine earth fraction of the soil except in the case of skeletal soils ( > 35% coarse fraction ) where it applies to the whole soil. The classes are described in Webb and Wilson (1995) and the user should also refer to the item grav_class for a description of the topsoil gravel content of soils. For the 2nd Edition Gisborne-East Coast mapping, particle size is recorded as undefined as soils were mapped directly to the New Zealand Soil Classification.

Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layers contains the permeability profile attribute. Permeability is the rate that water moves through saturated soil. The permeability of a soil profile is related to potential rooting depth, depth to a slowly permeable horizon and internal soil drainage. Permeablity classes are from Clayden and Webb (1994).
