Question

Why do sandy soils tend to be well aerated and dry? [3 marks]

Answer 1

Sandy soils tend to be well-aerated because:

• Sand particles are quite large. They cannot fit close together, so there are large spaces between them. [1 mark]
• These spaces are filled with air due to which sandy soils tend to be well aerated. [1 mark]

Sandy soils tend to be dry because water drains quickly through the large spaces between their particles. [1 mark]
