Transcript of Pedosphere Hadrava Vít Semrádová Martina Šudomová Karolína Sources: Google.cz Textbook.
What is pedosphere ?
• Pedosphere = Soil packaging Country
• Arises from a combination pedogenic substrate of living organisms, their dead bodies, climate, relief and time
Loam soils
• Large particles from 0.002 to 0.06 mm
• Deep horizon, the most agriculturally used
• In the lowlands
Soil types
• Black soils Peat soils• Brown soils Rendzina (limy soils)• Kambiz Alluvial soils• Podzol soils Gleyed soils
Black soil
• It is one of the most fergile soils on Earth
• It has got a high content of nutrients • It has got a huge humic horizon
• It appears in lowlands and warmer areas
• For examle in Hungary and Ukraine
Brown soil
• It appears in higher altitudes than black soils
• It appears mostly in moderately warm and humid areas
• Brown soil is quite fertile • For example in Benelux
Kambiz
• Can be created of all types of bedrock (sedimentary, metamorphosed also eruptive)
• It is in the highlands • For example in the
Czech Republic
Podzolic soils
• It is acid soil with low quantity of nutrients
• Coniferous trees grow on it • It ranges the cold mountainous
areas with wet climate • It has thin layer of humus • Such as Russia,
Scandinavia and Canada.
Rendzina (limy soils)
• It is found in mountainous areas • It is linked to the limestone subsoil • Croatia and England
Alluvial soils
• They surround rivers • They are mostly flooded • The most of the nutrients are flushed
away, and they are therefore less fertile
Gley soils
• They are affected by the lower water, so they are called swamps
• They have low level of oxygen - their discoloration.
