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 ...
Psathyrostachys juncea is a perennial bunch grass that grows in tufts that may be up to 1 metre (3.3 ft) tall or taller. The grass is long-lived and known to persist in cultivation for 25 years or more. The grass has a dense root network beneath each clump; there are no rhizomes or stolons. The roots can reach 3 metres (9.8 ft) deep into the soil.
Taeniopoda eques, the western horse lubber grasshopper, is a relatively large grasshopper species of the family Romaleidae found in arid and semi-arid parts of southwestern United States to central and southwestern Mexico.
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. [4] Depending on soil and moisture conditions, it grows to a height of 1–3 m (3.3–9.8 ft). The stem base turns blue or purple as it matures. Big bluestem blooms in the summer and seeds into the fall.
Johnson grass that is resistant to the common herbicide glyphosate has been found in Argentina and the United States. [2] [3] [4] It is considered to be one of the ten worst weeds in the world. [5] In the United States, Johnson grass is listed as either a noxious or quarantined weed in 19 states. [6]
It has relatively deep roots and propagates relatively rapidly horizontally from its root system but grows to only 2–5 inches (5–13 cm) in above-ground height, basically eliminating the need for mowing lawns that use it. It cannot be reproduced by seed and thus depends on sod plugs or sprigging for its production. [13]

It is also known as timothy-grass, meadow cat's-tail or common cat's tail. [3] It is a member of the genus Phleum , consisting of about 15 species of annual and perennial grasses. It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th ...
