Why farmers often add calcium oxide to the soil?

Farmers often add calcium oxide to the soil to raise the pH level of acidic soils. Calcium oxide, also known as quicklime, reacts with water in the soil to form calcium hydroxide, which helps to neutralize the acidity in the soil. This process, known as liming, helps to improve soil structure, increase nutrient availability, and promote healthier plant growth. Additionally, calcium oxide can also help to reduce the toxicity of certain elements in the soil, such as aluminum, which can be harmful to plant growth.
