Question

Give the diagrammatic representation of soil components.

Answer 1

There are five basic components of soil that, when present in the proper amounts, are the backbone of all terrestrial plant ecosystems. Figure 1. Soil is composed of a matrix of minerals, organic matter, air, and water.

Answer 2

All types of soil may be composed of four basic components.

They are minerals, water, air and organic components.

A soil is made up of 45% minerals, 5% organic matter, 25% water and 25% air.

However, the four soil components may vary tremendously in different soil types.

Air and water is present in pore spaces between solid particles of soil.

Also, the air-filled pore space ratio and the water-filled pore space ration can vary depending on the throughflow, flooding, precipitation and groundwater discharge.
