Abstract: The soils of the Marlborough Sounds are briefly described in terms of three broad soil-physiographic units based on climate: (1) Soils of the lowlands with weak dry season, (2) Soils of the lowlands with very weak or negligible dry season, and (J) Soils of the cool uplands with negligible dry season. Each of these units is further subdivided on the basis of parent material and topography. Overall morphological and physical properties and nutrient status of the soils are outlined together with a summary of soil physical and soil nutrient limitations to exotic forest growth.
Soils of the lowlands formed from greywacke, schist or basic volcanic rocks generally have slight physical limitations and moderate nutrient limitations to exotic forest growth. Soils of the uplands formed from greywacke or schist have moderate to severe physical limitations and moderate nutrient limitations. Soils formed from serpentine generally have moderate or moderate to severe physical limitations and severe nutrient limitations to exotic forest growth.
