Sod

Sod is the upper layer of turf that is harvested for transplanting. Turf consists of a variable thickness of a soil medium that supports a community of turfgrasses. Sod is typically made with grasses that spread laterally through the soil and form a dense mat. In British and Australian English, sod is more commonly known as turf and the term sod is mainly used in agriculture. Sod is used to establish lawns or other greenways in spaces like golf courses or sports stadiums. Typically, after construction or other landscape disruption, builders, owners, and landscape specialists place sod to establish a grass cover. Sod is grown on specialized farms; the grass is grown for 12 to 18 months before the sod is cut from the top layer of the soil and prepared for transportation. Sod is often cut in either squares or rolls, making it easier to transport and distribute. Different species of grass are grown in different geographic regions because of the differing climatic conditions. More recently, some producers have developed turf mixes that include wildflowers and other native plants.
