Soda carbonate soils characteristics and classification

Soil is one of the most important elements of our planet. The spread of plant organisms, as well as a crop that is extremely important for humans, depends on the quality and condition of the soil. There are many varieties of soil, among which sod-carbonate. You can meet this type of soil in brown forests. The soils of this species are formed fragmentarily and most often they can be found in places containing calcium carbonate, that is, closer to the territories in which various breeds are located (for example, limestone, marble, dolomites, marls, clay, pr.).

Characteristic, signs and composition of the soil

As a rule, sod-carbonate soils can be found on a slope, a plain area, a flat and increased element of the relief. They are formed near the breeds, which include the fragmentary material of the lime composition. The soil can be under forest, meadow and shrub type of plant world.

A distinctive feature of sod-carbonate soils is the high content of humus (up to 10% or more). The soil may also have such elements as humic acids. In most cases, examining this type of soil, the upper horizons give a neutral reaction, the lower ones alkaline; Very rarely weakly. The degree of unsaturation is affected by the depth of carbonate. So, at high levels, the indicator is in the range from 5 to 10%, at low up to 40%.

Sod-carbonate soils are quite peculiar. Despite the fact that they are formed under forest vegetation, many processes that are characteristic of this type of soil are weakened or completely absent. For example, in sod-carbonate soils there are no signs of leaching or re-deposit. This is due to the fact that the plant residues, entering the ground, decompose in an environment with a high calcium content. As a result, there is an increase in the amount of humic acid and the formation of sedentary organomineral compounds, as a result of which the humus-accumulative horizon is formed.

Morphological soil profile

Sod-carbonate soil consists of such horizons:

  • A0 power is from 6 to 8 cm; The forest litter in the forest litter of a poorly spread vegetable opad;
  • A1 power from 5 to 30 cm; humus-accumulative horizon of brownish-gray or dark gray color, with plant roots;
  • B power from 10 to 50 cm; a lumpy layer of brownish-gray color;
  • CCA dense, loose form.
  • Gradually, this type of soil evolves and goes into the soil of the podzolic type.

    Types of sod carbonate soils

    This type of soil is ideal for vineyards and the construction of gardens. It was established that it is the sod-carbonate soil that has high fertility. But before planting plants, you should delve into the process and choose the most suitable soil option. The following types of soil exist:

  • typical-distributed in brown-earth regions. Most often, you can meet in broad-leaved, oak, butterfly-bottom forests near the slightly surpassed, low-power Aluvius of Lime. The total capacity of the profile is about 20-40 cm and contains crushed stone, fragments of rocks. The soil contains humus about 10-25%;
  • Excessed-distributed by fragments in brown-earth regions. It is found in broadleaved forests, on the weathering and powerful thickness of Elyuvia. Humus content is about 10-18%. Power varies from 40 to 70 cm.
  • Sod-carbonate soils are suitable for growing agricultural crops, high-use plantings and broad-leaved rocks.
