Which of the following soil types is the most permeable?
Answer Details
Sand is the most permeable soil type. Permeability refers to the soil's ability to allow water to pass through it. Sand has larger particles with wider spaces between them, which allows water to flow more easily through the soil. This makes it easier for plant roots to access water and nutrients in the soil. In contrast, clay soils have smaller particles with less space between them, which makes it more difficult for water to pass through. Loam is a combination of sand, silt, and clay, and its permeability depends on the proportions of these components. Laterite soils are typically rich in iron and aluminum, which makes them hard and impermeable. Peat soils are composed of partially decayed organic matter and tend to be waterlogged, which reduces their permeability.
