What is pedosphere ?

• Pedosphere = Soil packaging Country

• Arises from a combination pedogenic substrate of living organisms, their dead bodies, climate, relief and time

Soil species

• Clay (heavy)• Loam soils (medium

heavy)• Sandy (light)

Clay

• Particles are smaller than 0,002 mm

Loam soils

• Large particles from 0.002 to 0.06 mm

• Deep horizon, the most agriculturally used

• In the lowlands

Sandy

• Particles are large 0,06 – 0,2 mm • Good permeability and airing of the soil• Few nutrients

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.

Peat soils

• Have a high proportion of organic substances formed by turf

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.

Questions

• Why we can say that nature knows all sorts of waste?

• What soil types are there in the vicinity of your school and residence? What are their characteristics?

• Name the types of soil in this picture.
