Order

  1. Alfisols represent the youngest forest soil order.
  2. Because of their productivity and abundance, the Alfisols represent one of the more important soil orders. (Web site)
  3. The principal soil orders in western-montane forests are Inceptisols, Alfisols, Andisols, and Mollisols. (Web site)
  4. Alfisols which are relatively old soils showing pronounced characteristics to qualify for this order are denoted by 'Pale' (e.g. (Web site)

Regime
