Livestock and no-till: do they mix? locations
Aims

To investigate the effects of grazing livestock in no-till paddocks on soil structure, soil compaction and soil moisture, weed seed burial and carbon/nitrogen cycling in no-till farming systems.

Key messages
  • Modest autumn grazing of no-till crop stubbles sometimes leads to small measurable increases in surface soil bulk density.
  • In two seasons, on soils in the Mallee and Wimmera, modest autumn grazing of no-till crop stubbles had no measurable effect on crop yield, quality or weed seed burial.
