Which soil component is associated with coarse texture, allowing for easier leaching?

• A. Clay
• B. Silt
• C. Sand
• D. Organic matter

Answer: (C)

The correct answer is sand, as it is the soil component characterized by larger particle sizes compared to clay and silt. This coarse texture allows for greater spacing between particles, which enhances drainage and aeration. When it comes to leaching, sandy soil facilitates the movement of water through the soil profile more quickly than finer textured soils. As water moves swiftly through sandy soils, it can carry nutrients and contaminants with it, leading to effective leaching. In contrast, clay, due to its small particle size and compact nature, retains water and nutrients more effectively, resulting in slower leaching. Similarly, silt, which has intermediate particle sizes, provides moderate drainage but does not facilitate leaching to the same extent as sand. Organic matter can improve soil structure and water-holding capacity, thereby influencing leaching but does not inherently possess the coarse texture associated with sandy soils. Thus, sand is the component specifically linked to both coarse texture and easier leaching.
