5.11 - Andisols
Soils form in volcanic ash and cinders near or downwind from volcanic activity. Generally lacking in development, they are not extensively weathered, forming in deposits from geologically recent events. Usually of high natural fertility, they tend to accumulate organic matter readily and are of a ‘light’ nature (low bulk density) that is easily tilled. These soils generally have a high productivity potential.
Key Characteristics: Andisols
- Form in regions of recent volcanism
- Volcanic parent materials
- Generally high in natural fertility
- ‘Light’ soils that are easily cultivated.
- Potentially very productive soils
- Limited geographic distribution
- Extent of world ice-free land area: 1%
