permissible_values:
  a_horizon:
    text: a_horizon
    description: The surface horizon, also called topsoil. It has a defined soil structure,
      and is mostly made up of humus (decayed organic matter).
    aliases:
    - A_Horizon
  b_horizon:
    text: b_horizon
    description: Also known as the subsoil. It is greatly composed of material illuviated
      (washed in from) layers above it. It is typically denser than the A horizon
      and has a clayey texture.
    aliases:
    - B_Horizon
  c_horizon:
    text: c_horizon
    description: Also known as the substratum is unconsolidated material deepest in
      the pit and closest to the bedrock.
    aliases:
    - C_Horizon
  e_horizon:
    text: e_horizon
    description: Used to refer to subsurface horizons that have undergone a significant
      loss of minerals, also known as Eluviation (or leaching).
    aliases:
    - E_Horizon
  o_horizon:
    text: o_horizon
    description: The organic horizon. Typically at the top of the soil structure and
      is made up of mostly organic matter.
    aliases:
    - O_Horizon
  permafrost:
    text: permafrost
    description: Soil that continuously remains below 0 °C (32 °F) for two years or
      more.
    aliases:
    - Permafrost
  r_layer:
    text: r_layer
    description: Hard bedrock, which is usually the lowest layer. It is characterized
      by tightly bound and unbreakable materials.
    aliases:
    - R_Layer
  m_horizon:
    text: m_horizon
    description: Mineral horizon
    aliases:
    - M_Horizon
