What distinguishes sod from turf?

The distinguishing factor between sod and turf is that turf refers broadly to the grass and other plants that grow on the ground, which can include various grass cultivars suited for different climates and uses. Sod, on the other hand, is a specific form of turf that consists of soil, roots, and a layer of grass that is harvested and sold as rolled-up pieces or squares. This classification highlights that sod is essentially a component of turf but distinct in its form and preparation method, as it involves a pre-grown grassy surface with some soil attached that can be laid down to create a lawn.

The other options do not accurately define the distinction between sod and turf. For instance, sod is not solely made of soil and nutrients, nor is it exclusive to commercial landscapes, nor is turf limited to residential use. Understanding this difference is key for proper landscaping and maintenance practices.
