Turf refers to a layer of soil that is covered with grass and roots. It is commonly used in landscaping, sports fields, and gardens to create a green, attractive surface. Turf can be natural, consisting of real grass, or synthetic, made from materials like plastic to mimic the appearance of grass. In sports, turf is often used in stadiums and fields for games like football, soccer, and baseball. Synthetic turf provides a durable playing surface that requires less maintenance than natural grass. It can withstand heavy use and various weather conditions, making it a popular choice for athletic facilities.
