The impact of livestock on paddock health

Funding source

Trial details

  • To test whether soil fertility and health could be improved under a higher input system compared to a lower input and more traditional system.
Key messages
  • Grain yields increased with higher crop inputs and following grazing, they were further improved following a sown legume pasture and a more intensive grazing system.
  • There has been no measured change in soil organic carbon over the 4 year project as a result of varying crop and pasture inputs or grazing compared to not grazing crop stubbles or pastures.
