Short answer type Questions-
What is meant by soil profile? Explain.
Answers
A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D. Most important for plant growth, the A and B horizons are the top two layers of the soil
Detailed answer:-
It consists of the following layer:-
It consists of the following layer:- 1) O- horizon or surface litter:- is the region of freshly fallen leaves, organic debris and partially decomposed organic matter.
It consists of the following layer:- 1) O- horizon or surface litter:- is the region of freshly fallen leaves, organic debris and partially decomposed organic matter. 2) A- horizon or topsoil:- is the region of partially decomposed organic matter (humus), plant roots, living organisms and some inorganic minerals.
