The dataset contains polygons of soils of King Country mapped at 1:63360. The attributes contain the soil series and the soil classification. No analytical properties of the soils are included.

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 soil salinity which is measured as percent soluble salts (g/100g soil). High salinity is detrimental effects on plant growth and yield, can reduce water quality and soil erosion. Salinity is an important land degradation problem.

The dataset contains polygons of soils of Kaingaroa Plateau, mapped at 1:100 000. This dataset is compiled from earlier reports by Pullar (1980), Vucetich et al (1960), and Vucetich and Wells (1978).
The attributes contain the soil series and the soil classification. No analytical properties of the soil are included.

The dataset contains polygons of soils of Part Eltham County mapped at 1:50000. The attributes contain the soil series and the soil classification. No analytical properties of the soils are included.

The dataset contains polygons of soils of Rangitikei County, mapped at 1:63360. Existing soil data by Cowie et al. (1967) were incorporated into this survey.
The attributes contain the soil series and the soil classification. No analytical properties of the soil are included.

This layer contains best available data as at 2000 for total carbon (organic matter content) which is estimated as weighted averages for the upper part of the soil profile from 0-0.2 m depth, and expressed as a percentage.

The dataset contains polygons of soils of Ohinemuri County mapped at 1:63360. The attributes contain the soil series and the soil classification. No analytical properties of the soil are included.

The dataset contains polygons of soils of Franklin County mapped at 1:63 360. The attributes contain the soil series and the soil classification. No analytical properties of the soil are included.

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 layer contains phosphate retention attributes. Phosphate retention (P retention) is estimated as weighted averages for the upper part of the soil profile from 0-0.2 m depth, and expressed as a percentage. The classes are described more fully in Blakemore et al. (1987) and Webb and Wilson (1995).
