Soil formation

Let us first know about the Soil

Due to the frequent deforestation, Soil got angry and rebelled.

Soil is the fertile surface of the earth, formed from a mixture of organic and inorganic material which supports plant growth.

They stopped giving their benefits to humans.

Soil helps in 1. Providing water and mineral to the plants.

2. Act as a substratum for a variety of organisms such as bacteria.

3.Site of decomposition of plant and animal bodies.

Government seeks Prof. Ramanuj’s help who is a renowned Pedologist.

The study of soil is called .

Let us discuss the Soil formation

To sort this issue Ramanuj created the artificial soil. So that it can be compared with the natural soil.

He uses a similar process through which natural soil forms.

Soil develops gradually by the fragmentation and corrosion of rocks and with the accumulation of organic matter.

Soil formation involves Weathering and Pedogonesis.

is the breaking of rocks into fine particles.

Weathering involves: Physical Weathering, due to heating and cooling, wetting and drying, glaciation.

Chemical weathering, due to hydration, hydrolysis, carbonization, and oxidation.

Biological weathering by bacteria, fungi, and lichens.

The weathered mineral matter is changed into the soil by the process of .

Pedogenesis is restricted to the superficial layer of the earth.

Pedogenesis involves Humification and Eluviation and Illuviation.

Humification: Formation of humus which is essential for starting biological activities.

Eluviation and Illuviation are the two process that brings about transport and deposition.

Let us learn about Types of Soil.

Soil is of two types: Residual soil and Transported soil.

Residual soil is mature soil that is formed by weathering and pedogenesis of the rocks.

Transported soil is brought from other places depending upon the agency involved in carrying.

This soil of four types: Alluvial soil, Colluvial soil, Eolian soil, and Glacial soil.

Artificial soil promised to the natural soil that human will do plantation and stop deforesting as much as possible.

Natural soil got convinced and started helping humans.

Revision

Soil is the fertile surface of the earth that supports plant growth.

The study of soil is called Pedology.

Soil formation involves Weathering and Pedogonesis.

Soil is of two types: Residual Soil and Transported Soil.

Transported soil is of four types: Alluvial soil, Colluvial soil, Eolian soil and Glacial soil.

The End.
