The four main components of soil are rocks (minerals), water, air and organic material (leaves and decomposed animals, for example).
What are the constituents of soil?
As a whole, soil is made up from four constituents: mineral material, organic material, air and water. There are considered to be three main mineral parts to soil; ‘sand’, ‘silt’ and ‘clay’. These parts give the soil its ‘mineral texture’.
