Axonopus compressus: Brief Summary
provided by wikipedia EN
Axonopus compressus (syn. Axonopus compressus (Sw.) P.Beauv. var. australis G.A.Black, Milium compressum Sw., Paspalum compressum (Sw.) Nees, Paspalum platycaule Willd. ex Steud., Paspalum platycaulon Poir.) is a species of grass. It is often used as a permanent pasture, groundcover, and turf in moist, low fertility soils, particularly in shaded situations. It is generally too low-growing to be useful in cut-and-carry systems or for fodder conservation.
While not optimal, it is occasionally used for football fields especially those which are not for elite competitions or where only a low level of maintenance can be done.
