What type of soil is in New Zealand?

Does Auckland have fertile soil?

Hilly areas The undulating land of South Auckland and Waikato is some of the most fertile in the country. The soil is made up of layers of volcanic ash, making it free-draining and easy to cultivate. Some soils are formed from flood gravels, and need drainage and fertiliser to be productive.

Is sand granular soil?

Granular soil means gravel, sand, or silt, (coarse grained soil) with little or no clay content. Granular soil has no cohesive strength. Some moist granular soils exhibit apparent cohesion. Granular soil cannot be molded when moist and crumbles easily when dry.

Are Allophanic soils fertile?

The soils are generally deep rooting and fertile, unless rock or massive clay is present. Recent soils occur throughout New Zealand in young landscapes, including alluvial floodplains, unstable steep slopes, and slopes mantled by young volcanic ash.

Does New Zealand have good soil?

How do I know what type of soil is in my garden?

• Clay soil has a smearing quality, and is sticky when wet.
• Pure silt soils are rare, especially in gardens.

What soil type is clay?

Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients. Clay soils remain wet and cold in winter and dry out in summer. These soils are made of over 25 percent clay, and because of the spaces found between clay particles, clay soils hold a high amount of water.

What type of soil do we have in New Zealand?

What type of soil is found in the North Island?

This map shows the locations of the main soil types in the North Island. Most noticeably, Granular and Oxidic soils are limited to the warmer Northland and South Auckland regions, and Allophanic and Pumice soils derived from volcanic ash are concentrated in the central part of the island.

Where do allophanic soils occur in New Zealand?

Allophanic soils occur dominantly in North Island volcanic ash, and in the weathering products of other volcanic rocks. They also occur in the weathering products of greywacke in the South Island high country (Total area = 1,367,388 ha, 5 \% of land in New Zealand).

Where are pumice soils found in New Zealand?
