Detailed explanation-1: -Tundra soils are usually classified as Gelisols or Cryosols, depending on the soil classification system used.

Detailed explanation-2: -The soil of the tundra is also nutrient poor, so it lacks nitrogen and phosphorus – two important elements plants need to grow. This keeps the plants small and makes plant growth slow.

Detailed explanation-3: -The soil in the Arctic is largely permafrost or soil that remains frozen year-round, leaving only a thin surface layer of thawed soil in summer for plant roots to grow in. Tundra soil is also scarce in many of the nutrients that plants need to grow.

Detailed explanation-4: -The Tundra soil has a poor quality of soils. In the Tundra, they have very low in nutrient and minerals. The soil also become frozen a short ways below the ground due to extremely low temperatures of the Tundra. Since the soil is frozen, plants aren’t able to grow their roots deep into the ground.
