For different climatic conditions and locations of the regions, certain types of soil are characteristic. Due to the unique composition of the soil in a particular area, plants typical of the region grow. The layer that forms between the chernozem steppes and podzolic soils is called gray forest lands. Both in terms of location, properties, and nutrients, the soil occupies a middle place. At the moment, geographers cannot agree on the origin of gray forest soils.
General characteristics and location of soils
In most cases, gray forest soils are formed in a dry temperate continental climate. The processes of soil podzolization are very slow, since in these regions there is an insignificant amount of precipitation and sunny days prevail. At the same time, gray forest lands contribute to the acceleration and intensification of the sod formation process.
Soils spread in deciduous-forest zones. They are acidic or slightly acidic in the upper levels and neutral or slightly alkaline in the lower levels. The composition of the soil includes an important element of humus, its content reaches 3-8%.
Morphological soil profile
Gray forest soils have a peculiar structure consisting of five layers:
In order for soils to please with fertility, they must be properly used. You also need to choose one of the subtypes of soil for growing crops. Despite the fact that soil varieties are similar in composition and properties, they have striking differences and opportunities.
Gray soil types
The subtype of gray soils is directly affected by the podzolization process. The following types of forest lands are distinguished depending on its flow:
Gray soils are fertile, but it is recommended to feed them with organic and mineral fertilizers, as well as liming and deepening the arable layer. On such lands, agricultural crops can be grown, for example, corn, beets, potatoes.
