Correct answer: C. For neutralizing acidic soils
- A. For chlorophyll development
- B. As fertilizer
- C. For neutralizing acidic soils
- D. To increase fruit production
Explanation
One of the important uses of lime in agriculture is for neutralizing acidic soils. Acidic soils, characterized by a low pH, can adversely affect plant growth by limiting the availability of essential nutrients and potentially toxic levels of certain elements. Lime, typically in the form of calcium carbonate (CaCO3) or calcium hydroxide (Ca(OH)2), is applied to acidic soils to raise their pH levels and make them more neutral or slightly alkaline.When lime is applied to acidic soils, it reacts with the acidic components present, such as hydrogen ions (H+), aluminum ions (Al3+), and manganese ions (Mn2+), forming insoluble compounds and water. This reaction helps to neutralize the acidity of the soil, improve soil structure, increase nutrient availability, and create a more favorable environment for plant growth.
