Distinguish between Azonal and Intrazonal soil 

Azonal soils are young soils without a clear soil profile.

• They are soils that have not been exposed to soil forming processes for a long time therefore they are immature.
• They are skeletal soils with shallow profiles and show similar characteristics of the original parent
• Azonal soils are divided into two groups e. Lithosols and Regosols – derived form unconsolidated materials such as aluminum, sand, volcanic ash etc.

Example of Azonal soils include:

• Scree soils/ mountain soils found on mountain slopes formed from accumulation of weathered angular rock
• Alluvial soils – river borne materials g. silt, mud etc.
• Marine soils – as a result of wave action g. mud, clay etc.
• Glacial soils – due to glacial action g. till soils, fluvio-glacial soils etc.
• Windblown soils (Aeolin) g. loess, dune soils etc.
• Volcanic soils – recent Lava and ash

While

Intrazonal soils are soils that occur where special conditions of parent rock or drainage exert a stronger influence. E.g large amounts of salts, presence of much water etc.

Examples of Intrazonal soils Include

• Saline soils (Halomorphic soils) -· have high levels of soluble salts such as solonchaks and solonetz soils.
• Peat soils (Hydromorphic soils)- occur in water logged conditions g. meadow soils, gley soils etc.
• Calcareous soils (Calcimorphic soils)- formed from limestone parent rock g. Rendzina and Terra rossa.
