Explain soil profile and explain each …

A vertical section (or cutting) through the soil showing the different layers of soil is called soil profile. Soil profile consists of three different layers of soil. Horizon Each layer of soil is called a horizon. The three lavers of soil in the soil profile are: 1) A-horizon (or Top-soil) 2)B-horizon (or Sub-soil) 3)C-horizon (or Sub-stratum) A- horizon- * This is the topmost horizon and also called as topsoil. * Contains large amount of humus and minerals. * Topsoil is soft and porous. * Capacity of water retention of this soil is more. * Hold the roots of the plants entirely. * House of many living organisms such as worms, rodents, moles and beetles.      2)   B-horizon-            * Second layer of soil profile and also called as middle layer.            * Contains larger amount of minerals than humus.            * More compact and harder than topsoil.     3)    C-horizon-            * Third layer of soil profile.            * Small lumps of rocks are found with cracks and cervices.    4)     Bedrock-            * The last layer of soil profile.            * Very hard.            * This layer is even difficult to dig with a spade .

A vertical section (or cutting) through the soil showing the different layers of soil is called soil profile. Soil profile consists of three different layers of soil.

Horizon

Each layer of soil is called a horizon. The three lavers of soil in the soil profile are:

1) A-horizon (or Top-soil)

2)B-horizon (or Sub-soil)

3)C-horizon (or Sub-stratum)

• A- horizon-

* This is the topmost horizon and also called as topsoil.

* Contains large amount of humus and minerals.

* Topsoil is soft and porous.

* Capacity of water retention of this soil is more.

* Hold the roots of the plants entirely.

* House of many living organisms such as worms, rodents, moles and beetles.

     2)   B-horizon-

           * Second layer of soil profile and also called as middle layer.

           * Contains larger amount of minerals than humus.

           * More compact and harder than topsoil.

    3)    C-horizon-

           * Third layer of soil profile.

           * Small lumps of rocks are found with cracks and cervices.

   4)     Bedrock-

           * The last layer of soil profile.

           * Very hard.

           * This layer is even difficult to dig with a spade .
