Alfisols


Profile of altisol

Alfisols (from the soil science term Pedalfer – aluminum and iron) are similar to Ultisols but are less intensively weathered and less acidic.

They tend to be more inherently fertile than Ultisols and are located in similar climatic regions, typically under forest vegetation.

They are also more common than Ultisols, occupying about 10% of the glacier-free land surface.
