Which statement best describes the effect of tilling on soil structure?

• A. Improves drainage
• B. Destroys soil structure
• C. Adds organic matter
• D. Reduces erosion

Answer: (B)

Tilling breaks apart the soil’s organized clumps (aggregates) and collapses the pore network that water and roots rely on. This physical disruption weakens the soil structure, making it more prone to compaction and surface crusting as it settles. In the long run, tillage tends to degrade structure rather than build it up. While it can temporarily loosen very compacted layers and alter drainage briefly, it does not add organic matter and often increases erosion risk by exposing bare soil and destroying protective aggregates.
