designation of the soil horizon.
-- Description --
The FAO horizon notation is a code system characterizing horizons regarding the dominant soil forming processes that have been active during the horizon formation. This code summarizes many observations of the soil description and gives an impression about the genetic processes that have formed the soil under observation.
NOTE The horizon notation is a combination of several letter, number and symbols.
