Trial details

Aims

To test whether soil health and fertility can be improved under a higher carbon input system with or without grazing.

Key messages
  • The high input pasture treatment provided the opportunity to carry 8 DSE/ha with an estimated gross margin of $240/ha, however it was unable to utilise plant available water above 50% of potential water use efficiency (WUE).
