Soil Genesis upsc

As we know that there are number of spare likely thermosphere atmosphere Hydrosphere and biosphere which collectively give birth to soil. Its means soil is a function of lithospheric atmospheric Hydrospheric and biospheric process and soil is the mixture and outcome of this four spheres.

Lithosphere ( parent material) 

Parent materials means some material from lithosphere circuits and silt and clay brought down by lithosphere.

Atmosphere

Means different gases come between the words of tabs on the basis of pedology is comes.

Pedology

• The scientific study of the morphology competition and spatial distribution of soil including the classification and use. 

Pedogenesis

• The formation of soil by natural process from parent material
• Parent material means the rock of Mountain plateau and plain

Cryo pedagogy

• The scientific study of formation and characteristics of soil in Perigalacial reasons
• Tundra and Taiga region are most suitable area for it
• Freeze and third cycle of soil is develop

Classification of soil

Classification of soil is great challenge because some Classified on the basis of colour, texture (sand silt clay), structure PH values fertility and productivity. But we generally classified soil on

• Laterization
• Gleication
• Podzoliation
• Calcification
• Salinization

Podzoliation

• Breaking of frog in different parts
• It is a coarse soil
• It's done by the high range of temperature in Taiga forest region
• In this reason rainfall and temperature is the average

Salization

• Rainfall is minimum and temperature is high
• Maximum temperature found in desert region along cancer and capricorn to the west of continents and their rainfall and precipitation is minimum below 20 to 40 mm
• It is not suitable for any crops except Zerophaits

Gleization

• Area where the rainfall is sufficient but temperature is low
• It will found in temperate region where temperature is less but rainfall is medium

Laterization

• Precipitation and temperature is required very high
• Temperature and precipitation is maximum at equatorial region
• Climatic process

Calcification

• Less amount of precipitation and high temperature required
• North equator at Savannah range has less rainfall and high temperature because of varying position of sun
