Can kikuyu improve soil organic carbon levels on Kangaroo Island? locations

To investigate whether kikuyu improve soil organic carbon levels on Kangaroo Island.

Key messages

Perennial based pasture systems can offer numerous benefits, including increased access to fresh summer feed,
lowered water table with a decrease in associated salinity issues, and minimisation of surface erosion. While it
is premature to apply these results broadly across KI, these results suggest that the decision to switch to a perennial
pasture should not be made based solely upon anticipated changes in soil carbon levels.
