FSL Cation Exchange Capacity

Added

This dataset was first added to LRIS Portal on 28 May 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 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 Cation Exchange Capacity (CEC) which is estimated as weighted averages for the soil profile from 0-0.6 m depth and expressed in units of centimoles of charge per kg (cmoles (+)/kg).

LENZ - Exchangeable calcium

Added
30 May 2010

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).

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.

Vulnerability to Soil Structural Degradation

1913
85
Added
28 Oct 2010

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

Untimely cultivation, grazing and forestry operations when the soils are wet give rise to a rapid and marked loss of soil structure and a reduction in soil permeability and aeration owing to the compaction, deformation and consolidation of the topsoil and upper subsoil. This degradation results from the pressure of heavy machinery or treading by stock. Some soils are more at risk than others due to their poor resistance and resilience to compacting forces, poor drainage, limited water holding capacity, or higher rainfall.
