Reserve potassium (Kc) is a measure how much potassium is available to plants. There are three potassium pools: dissolved, extractable, and reserve potassium. Potassium (K) is continuously drawn from the extractable to the dissolved pool when it is used by plants, and likewise from the reserve pool to the extractable pool. The reserve potassium is held in minerals in the soil such as mica. An example of the utility of this information is for organic farmers, who are not allowed to add potassium chloride to their soils (they can add potassium sulphate, but this is much more expensive). Class 3 for Kc will indicate where organic farming is practical. If you zoom in on the map and click on a soil area it will show the Kc class (pot class). The classes are:

0 No data
1 Low (0-0.3 cmolK/kg)
2 Medium (0.3-0.6 cmolK/kg
3 High (>0.6 cmolK/kg)
4 Lakes
5 Alpine
6 Urban

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).

Added
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.

LENZ - Acid soluble phosphorous

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.
