What effect does tilling the soil have on its structure?

• A. Destroys soil structure
• B. Improves soil structure
• C. No effect on soil structure
• D. Increases soil nutrient content

Answer: (A)

Tilling disturbs the soil enough to break apart the natural aggregates that bind soil particles into stable clumps and to disrupt the network of pores that water and roots rely on. This destruction of the organized structure reduces stability, makes the surface more prone to crusting after drying, and increases the risk of compaction when the soil becomes wet again. While tilling can temporarily loosen the soil for planting, the lasting effect on the soil’s structure is a loss of its intact, well-structured framework that supports aeration, water movement, and rooting. It doesn’t inherently add nutrients, and there is typically a noticeable change in structure rather than no effect.
