What is one of the key functions of soil aggregates?

• A. To improve soil color
• B. To facilitate better drainage
• C. To enhance nutrient absorption
• D. To increase microbial activity

Answer: (B)

One of the key functions of soil aggregates is to facilitate better drainage. Soil aggregates are clumps or clusters of soil particles that have bonded together. Their structure creates larger pore spaces between the aggregates, which improves the movement of air and water through the soil. This enhanced drainage helps prevent water from pooling or creating saturated conditions that can harm root systems and soil health. When aggregates are well-formed, they not only allow for better water infiltration, but also promote the movement of nutrients, preventing runoff and ensuring that plants have access to the moisture and elements they need for healthy growth. Therefore, the role of soil aggregates in improving drainage is essential for maintaining a well-functioning ecosystem in the landscape.
