Correct option is D
The correct answer is: (D) All of the above
Explanation:
To correct soil acidity, various forms of lime materials can be added to the soil. These materials release calcium ions into the soil, which neutralize soil acidity and raise the pH. The common lime materials include:
Calcium carbonate (CaCO₃): A commonly used form of lime, known as agricultural lime.
Calcium oxide (CaO): Also known as quicklime, it is a highly reactive form of lime that works rapidly but is more difficult to handle due to its high reactivity.
Calcium hydroxide (Ca(OH)₂): Known as hydrated lime, it is a fast-acting lime material used to quickly neutralize acidic soils.
Information Key Points:
Calcium carbonate is commonly used due to its ease of handling and slow but steady action.
Calcium oxide reacts more rapidly, releasing heat when added to soil.
Calcium hydroxide is also effective for quick pH adjustment .
Lime materials provide calcium, which not only corrects soil acidity but also improves soil structure and nutrient availability.
