The deep fibrous root systems of switchgrass left a deep rich layer of organic matter in the soils of the Midwest, making those mollisol soils some of the most productive in the world. By returning switchgrass and other perennial prairie grasses as an agricultural crop, many marginal soils may benefit from increased levels of organic material ...
The main roots are 6–10 ft (1.8–3.0 m) deep, and the plants send out strong, tough rhizomes, so it forms very strong sod.
