Effect of four fertiliser regimes on the persistence of perennial native grasses

摘要：

It is often said that too much fertiliser will cause native grasses to die out but is it the fertiliser that causes such losses ?Perennial native grass pastures will generally respond to fertiliser, provided they contain a responsive legume.This is particularly true of those with a significant component of wallaby grass ( A ustrodanthonia spp), microlaena ( M icrolaena stipoides) or redgrass ( Bothriochloa macra).Garden et al.(2001 ), using wether sheep, suggests annual grasses reduce wallaby grass when higher rates of fertiliser are used.This paper provides data on the persistence of several native grasses following 12 years of fertiliser application at several different rates with a different livestock enterprise.
