    Study Notes

    Land Capability Classifications

    • Class I soils:

      • Few or no limitations/hazards.
      • Suitable for cultivated crops, pasture, range, woodland, or wildlife.
    • Class II soils:

      • Few limitations; simple conservation practices required.
      • Suitable for cultivated crops, pasture, range, woodland, or wildlife.
    • Class III soils:

      • More limitations and hazards than Class II.
      • Require complex conservation practices for cultivation.
      • Also suitable for cultivated crops, pasture, range, woodland, or wildlife.
    • Class IV soils:

      • Greater limitations than Class III, necessitating more complex conservation measures.
      • Suitable for cultivated crops, pasture, range, woodland, or wildlife.
    • Class V soils:

      • Little or no erosion hazard but other limitations hinder normal tillage.
      • Best suited for pasture, range, woodland, or wildlife.
    • Class VI soils:

      • Severe limitations making them generally unsuitable for cultivation.
      • Primarily for pasture, woodland, or wildlife.
    • Class VII soils:

      • Very severe limitations making them generally unsuitable for cultivation.
      • Also suited for grazing, woodland, or wildlife.
    • Class VIII soils:

      • Limitations prevent use for cultivated crops, pasture, range, or woodland.
      • May be utilized for recreation, wildlife, or water supply.

    Subclasses and Classifications

    • Subclass "w":

      • Represents wetness.
    • Subclass "s":

      • Stands for soil.
    • Subclass "c":

      • Denotes climate.

    Additional Concepts

    • Capability classification:

      • A practical grouping of soils based on their use and management needs.
    • Subclasses:

      • Indicate principal types of conservation practices involved.
    • Capability unit:

      • Contains soils that are similar in plant growth and management requirements.
