Which of the following situations – ‘A’ or ‘B’ – is advantageous for absorption of water and minerals? Why?
Situation ‘A’ : Growth and branching of roots in the C-horizon. Situation ‘B’ : Growth and branching of roots in A and B horizons.
Situation ‘B’ is beneficial for the plants growth because A-horizon is the top layer of the soil and Horizon B is the subsoil, next to A. Both of these layers are rich in water, minerals and humus.
