Which type of soil is likely to have the highest saturation and moisture retention?

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

Answer: (B)

Clay soil is known for its high saturation and moisture retention capabilities. This is due to its fine particles, which create small pore spaces that can hold onto water effectively. Clay's compact nature means that it retains moisture for longer periods compared to coarser soils like sandy soil, which allows water to drain quickly and does not hold moisture well.

In contrast, silty soil is also capable of retaining moisture but does not achieve the same level of saturation as clay. Silty soil has a medium particle size that offers better drainage than clay, making it less effective for moisture retention in comparison.

Loamy soil is a balanced mixture of sand, silt, and clay, providing good drainage as well as moisture retention. While it is considered ideal for gardening and landscaping due to its balance, it still does not match the high saturation level of clay soil.

Thus, the characteristics of clay soil, with its dense structure and high capacity for water retention, make it the type of soil most likely to exhibit the highest saturation and moisture retention.
