The carpetgrass cover explains the high TOC levels in Pasture, given that it produces a large amount of plant matter with high C : N ratio (Table 3) and has a root system that is efficient in exploring at depth.
The higher levels of oxidisable C in Pasture may result from the rapid growth (shoot and root) and plant mass increase of broadleaf carpetgrass, which was associated with high TOC levels (Table 2).
Augustinegrass, carpetgrass, centipedegrass, and bahiagrass, however, are usually grown only in the warmest regions of the South.
Carpetgrass is native to the West Indies and Central America and is grown in the warmest areas of the South.
Carpetgrass is considered an unattractive species, partially because of the many tall, coarse seedheads developed throughout the summer (Figure 3-17).

Grasses that have a slow growth rate such as the fine fescues, centipedegrass, and carpetgrass
need significantly less fertilization.
