Abstract

NORTH AUCKLAND is covered by a large variety of soils. These have developed on sandstones, mudstones, andesitic rocks, basalt, volcanic ash and mixtures of these materials. Further, on each type of parent material, time and environment have combined to create a range or "suite" of soils. The term and concept of soil "suites" was developed by Taylor (1952), formerly Director of the New Zealand Soil Bureau. Dr Taylor's system of grouping these soils has been of very great help in planning field and laboratory experiments. Table 1 outlines a simplified model of a soil suite developed on sandstone. Natural fertility is highest on the A type soils, very much lower on the B and C type soils and very low on the D and E soils. The last two (D and E) and part of the C soils used to be dug for kauri gum. Hence they are known as gumland soils.
