THE ADDITION OF LIME TO CLAYED SOIL SERVES TO

• A. aid water retention
• B. close up the texture
• C. prevent water logging
• D. improve capillary action ✓

The answer to the question is: D. improve capillary action

The addition of lime to clayed soil serves to improve capillary action. Lime, also known as calcium hydroxide or calcium oxide, is commonly added to clay soils to alter their properties and improve their suitability for plant growth. When lime is added to clayed soil, it helps to break down the clay particles and improve the soil structure. This process, in turn, enhances the soil’s capillary action, which refers to its ability to draw water upward from lower layers through small spaces between soil particles.

Clay soils are known for their poor drainage and tendency to become waterlogged, especially during periods of heavy rainfall. The addition of lime helps to mitigate these issues by improving the soil’s capillary action. By enhancing capillary action, lime-treated clay soils can better regulate water movement and distribution within the soil profile. This can be particularly beneficial for plant roots, as it ensures a more balanced supply of water and nutrients.
