What is a common method to manage soil acidity?

Applying lime to the soil is a common method to manage soil acidity because lime, primarily composed of calcium carbonate, helps to neutralize acidic soils. When lime is added to soil, it reacts with the acidic components, increasing the pH level. This process makes the soil less acidic and more conducive to plant growth, thereby improving nutrient availability and overall soil health. As a result, crops can thrive better in neutral to slightly alkaline soils, which is crucial for optimizing yields.

Other methods mentioned, such as using pesticides, reducing water usage, and implementing crop rotation, do not specifically address the issue of soil acidity. Pesticides are primarily aimed at controlling pests and diseases rather than altering soil chemistry. Reducing water usage may have various benefits but does not influence soil pH levels directly. Crop rotation can improve soil health and fertility but without directly adding lime or other amendments, it typically does not manage soil acidity effectively.
