What has fertile soil chernozem?

What does the word chernozem mean?
humus
Definition of chernozem : any of a group of dark-colored zonal soils with a deep rich humus horizon found in regions (such as the grasslands of central North America) of temperate to cool climate.
What are the characteristics of chernozem soil?
Chernozem surface soils contain between 5 and 15 percent of `mild’ humus with a high proportion of humic acids and a C/N-ratio that is typically around 10. The surface horizon is neutral in reaction (pH 6.5-7.5) but the pH may reach a value of 7.5-8.5 in the subsoil, particularly where there is accumulation of lime.
What are podzolic soils?
podzolic soil, podzolic also spelled podsolic, also called lessivé soil, soil usually forming in a broadleaf forest and characterized by moderate leaching, which produces an accumulation of clay and, to some degree, iron that have been transported (eluviated) from another area by water.
Why is Ukraine so fertile?
Chernozem is the rich black soil that makes Ukraine one of the most fertile places on Earth. It’s a soil that was formed from very fine mineral particles that prehistoric winds carried away from ancient glacial beds. “The wind acted as a huge filter,” says Dr. Léon Hardy, a Canadian geomorphologist in Ukraine.
Is black dirt fertile?
The black soils are also called as regur are fertile because they are highly moisture retentive, more clay content,which responds well to irrigation. The black soils are argillaceous contains many essential nutrients along with some content of humus as well.
Why is chernozem so beneficial for agriculture?
Chernozem is a very fertile soil that produces high agricultural yields and offers excellent agronomic conditions for the production of crops, especially cereals and oilseeds. As it decomposes, the color of the soil becomes darker and increases soil aggregation and the ability to attract and retain nutrients.
Is podzolic soil good?
Most Podzols are poor soils for agriculture due to the sandy portion, resulting in a low level of moisture and nutrients. Some are sandy and excessively drained. Others have shallow rooting zones and poor drainage due to subsoil cementation.
