Applying lime is a well-established method for managing soil acidity. Lime, which is primarily composed of calcium carbonate, reacts with the acidic components in the soil. This reaction raises the soil pH, effectively reducing acidity. A higher pH level is beneficial for many crops, as it can improve nutrient availability and enhance microbial activity in the soil, both of which contribute to healthier plant growth.

Other methods mentioned, such as applying compost or adding sand, are less effective for directly addressing soil acidity. While compost can improve soil structure and provide nutrients, it does not significantly alter soil pH. Similarly, adding sand primarily affects soil texture and drainage rather than acidity levels. Watering more frequently does not influence soil pH and may lead to water management issues instead.
