Question

How is humus a major factor in deciding the soil structure

Answer 1

yes the humus is a major factor in deciding the soil structure because the humus contains some raw materials

Answer 2

Humus is the major factor in deciding the soil structure because:

(a) Humus is a dark coloured colloidal material that constitutes the organic components of the soil. It is formed by the decomposition of plant and animal remains.  

(b)Humus usua lly increases the ability of the soil to resist erosion.

(c) allows water and air to penetrate deep into the soil making available for the roots of the plants

First, it enables the soil to hold more water. Even more important is its effect in promoting soil granulation and thus maintaining large pores through which water can enter and percolate downward. Humus provides a reservoir for the plant nutrients available in the soil for balanced plant growth
