Story: Kauri forest

Kauri podzol

Kauri podzol

Podzolised soils (weathered, poorly drained, acidic clays) are leached of most of the nutrients required for plant growth. However, kauri flourish on such soils and leave their mark in the form of ‘egg-cup podzols’ – nutrient-poor areas in the soil where individual trees once grew. The white streak in this soil from kauri forest in Northland is quartz sand, virtually devoid of nutrients, which have been leached to greater depths.
