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

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.

NZ Area Codes for recording specimen localities

Crosby et al. (1976) subdivided the New Zealand mainland (North, South, and Stewart Islands, plus nearby inshore islands) into 29 approximately equalsized areas, and defined two-letter codes for each. The codes and boundary definitions for these areas were provided on a separate, large map enclosed with the journal issue. These areas were modified from the areas used as weather forecast districts by the New Zealand Meteorological Service, and their main purpose was to facilitate the arrangement, retrieval, and documentation of specimens in the New Zealand Arthropod Collection (NZAC). The codes have subsequently been used in other collections, for computer databases, and in publications as a convenient way of categorising specimen data.

This database describes the soils of the pastoral and cropping land of Canterbury, from the Kowhai River in the north to the Rangitata River in the south, but not including Banks Peninsula. The original survey was mapped as a reconnaissance soil survey at 2 miles to the inch. These original soil boundaries have been very substantially revised and recompiled onto 1:50,000 scale topographic base by T.H. Webb in the 1990s and again in the 2000s.
