The main reason for using agricultural lime is to adjust soil pH. Soil acidity can significantly impact plant growth and nutrient availability. Agricultural lime, primarily composed of calcium carbonate, is applied to acid soils to raise the pH level, making the soil less acidic. This adjustment not only promotes healthier plant growth but also enhances the availability of essential nutrients such as nitrogen, phosphorus, and potassium, which might be locked away in highly acidic conditions. By increasing the soil pH, agricultural lime creates a more favorable environment for crop growth and contributes to overall soil health. Therefore, utilizing agricultural lime is a key practice for optimizing the growing conditions in agricultural fields.
