Which of the following statements is true about sandy soil?

Step 1: Analyze the question The question asks which statement correctly describes sandy soil. We need to recall the physical properties of sandy soil.

Step 2: Explain the concept Sandy soil is made up of large, coarse particles (0.05-2.0 mm). Because the particles are big, the spaces (pores) between them are large. This gives sandy soil these properties:

• Large air spaces, so it is well aerated
• Fast drainage, because water passes through quickly
• Low water retention, so it dries out quickly
• Light texture, so it is easy to dig or cultivate (farmers call it a "light soil")
• Low nutrient content, because nutrients are leached away with the draining water

By contrast, clay soil has tiny particles, small pores, poor drainage, poor aeration, and a heavy, sticky texture that is hard to dig.

Step 3: Evaluate each option

• A. Has limited air space: False. Sandy soil has large pore spaces and plenty of air. Limited air space describes clay.
• B. Is light and easy to dig: True. Coarse, loose particles make sandy soil light and easy to work.
• C. Drains slowly: False. Sandy soil drains quickly. Slow drainage describes clay.
• D. Is heavy and poorly aerated: False. This describes clay soil, not sandy soil.

Step 4: Answer The correct option is B: sandy soil is light and easy to dig.

Exam tip: Remember "Sand = Speedy" because water drains speedily through it. Sandy soil is light, airy, and fast-draining, while clay is heavy, sticky, and slow-draining. If an option describes sandy soil as heavy, poorly aerated, or slow to drain, it is really describing clay.
