Fertility of the soil supporting degraded native grassland at Trangie Agricultural Research Centre was either enhanced by addition of fertiliser, reduced by application of sugar, or left untreated. The experiment was repeated on sites where native perennial grasses were either absent or present at relatively low density. After two years, the DM yield of annuals was significantly lower, and DM yield of perennials (if present) significantly higher, in the reduced fertility treatment. If initially present, density of the two major native perennial grasses (Austrodanthonia caespitosa and Enteropogon acicularis) increased in the reduced fertility treatment but declined in the other two treatments. ...
