In which type of soil are you likely to find the slowest drainage?

• A. Sandy soil
• B. Clay soil
• C. Loamy soil
• D. Peaty soil

Answer: (B)

The correct choice reflects that clay soil has very tiny soil particles that pack closely together, creating a dense, compact structure. This characteristics limit the movement of water, resulting in very slow drainage. Due to the high level of clay content, water tends to pool on the surface rather than percolating through the soil, leading to saturation in wet conditions. In contrast, sandy soil, due to its larger particles and greater pore spaces, allows water to drain quickly. Loamy soil, which is a balanced mixture of sand, silt, and clay, typically has good drainage properties while still retaining some moisture. Peaty soil, often rich in organic material, retains water well but drains more effectively than clay, especially compared to pure clay soils. This understanding helps illustrate why clay soil is associated with the slowest drainage among the options.
