Hii user...

Good evening...

Here is ur answer....

Soil horizon.....:

If you visit a site , where earth has been dug for building a house , or look in a soil pit , or on road side cut , you will see various layer of soil . These layers are called soil horizon...

Now let us explore the different horizon of soil -

(1) O Horizon....

It is the top , organic layer of made up mostly of leaf litter and humus (decomposed organic matter )

(2) A horizon.....

This layer , also called top soil , is found below O Horizon . Seeds germinate and plants grow in this dark - coloured layer . It is made up of humus ( decomposed organic matter) mixed with minimal particles .

(3) B Horizon ....

It is also called the sub soil . This layer is beneath the A horizon and above the C Horizon . It contains clay and minerals deposit , like iron , aluminium , calcium carbonate etc ... It receives them , from layer above it , when mineraliged water drips from the top soil .

(4) C Horizon ...

It is the layer beneath the B Horizon . It consists of slightly broken up bed rock . Plant roots do not penetrate this layer and very little organic matter is found in this layer .

(5) R Horizon .....

This consists of the unweathered rock layer , called the bed rock . It is exists beneath all the other horizons ...
