Ground limestone is used to raise soil pH. - Leaving Cert Agricultural Science - Question (c) - 2019

This statement is True. Ground limestone, primarily composed of calcium carbonate (CaCO₃), is commonly used in agriculture to neutralize acidic soils and raise the pH. When ground limestone is added to soil, it reacts with the acids present, thereby increasing the pH level and improving the conditions for plant growth. The application of ground limestone can enhance nutrient availability, ensuring that vital nutrients are accessible to crops.
