Final answer:
The statement that agricultural lime can be used to lower the pH of an acidic turf is true. Lime raises the soil pH, reducing its acidity, and is essential for plant health and sustainable agriculture.
Step-by-step explanation:
The question, whether agricultural lime can be used to lower the pH of an established turf that is too acidic, is true. Applying agricultural lime to acidic soils serves to neutralize the acidity, which essentially raises the soil pH making it less acidic. In agricultural science, lime is a widely recognized remedy for acidic soils. Lime, which consists of compounds such as calcium carbonate, works by neutralizing acidic substances in the soil. This is important for plant health as most plants thrive in soil with a balanced pH. Acidic soils can also lead to aluminum toxicity, which inhibits root growth and affects the overall health of crops. Therefore, maintaining an optimal pH through liming is essential for sustainable agricultural production.
