Agricultural lime is a soil amendment made from crushed limestone, primarily composed of calcium carbonate. It is used to improve soil quality by raising the pH level, making it less acidic. This helps enhance nutrient availability for plants, promoting healthier growth and higher crop yields. Farmers often apply agricultural lime to fields to correct soil acidity, which can hinder plant development. Additionally, it can improve soil structure and increase microbial activity, benefiting overall soil health. Regular testing of soil pH can help determine the need for agricultural lime applications.
