What is a deciduous soil?

Deciduous forests have soils called Alfisols. These soils do not have a bleached E horizon, but do have clays that accumulate in the subsoils. Alfisols are very common in the Midwestern region, and are the most fertile type of forest soils. In the Southeastern US, there are coniferous forests and temperate forests.

Which of the following horizon is characteristic of forest soil?

Forest soils, where soil formation has been influenced by forest vegetation, are generally characterized by deeply rooted trees, significant ‘litter layers’ or O horizons, recycling of organic matter and nutrients, including wood, and wide varieties of soil-dwelling organisms (Figure 1).

What are the major land features of the deciduous forest including the soil type?

Landforms. In the Northern Hemisphere, the landscape over which temperate deciduous forests grow includes mountains, valleys, rolling hills, and flat plateaus.

What is the soil profile for the temperate forest?

Typical soils in the temperate rainforest include Andisols, soil formed from deposits of volcanic ash; Spodosols, soils dominated by sand; and Alfisols, soils with a clay-enriched B horizon.

What kind of soil is in deciduous forest?

Typical temperate deciduous forest soils are mull soils, which have a high level of organic matter especially close to the surface that is well mixed with mineral matter. Variations in soil materials and fertility have a strong influence on the types of trees that will dominate the forest.

How good is the soil in the deciduous forest?

As the leaves decompose, the nutrients contained in the leaves are absorbed by the soil. For this reason, the soils of this biome tend to be very fertile. Because this biome has fertile soil and a long, 5 to 6 month, growing season, many deciduous forests have been converted into agricultural regions.

What are the different soil horizons?

There are five soil horizons: O, A, E, B, and C. (R is used to denote bedrock.) There is no set order for these horizons within a soil. Some soil profiles have an A-C combination, some have an O-E-B, an O-A-B, or just an O.

What type of soil is in a deciduous forest?

The soils upon which deciduous forests thrive are gray-brown and brown podzols. They are slightly acidic and have a granular humus layer known as mull, which is a porous mixture of organic material and mineral soil. Mull humus harbours many bacteria and invertebrate animals such as earthworms.
