Year(s) 2010 - 2012
Contributor Hart Field Site Group
Trial location(s) Condowie, SA
Long-term stubble retention and reduced tillage - Condowie locations
Aims

To investigate the long term effects of different approaches to sustainable farming, especially in relation to soil moisture and soil quality.

Key messages
  • Crop water use and soil analysis values were very similar between the sites comparing long term reduced tillage and stubble retention.
  • Reduced tillage and stubble retention has significantly contributed to increasing organic carbon levels at these sites.
  • The grain yields of wheat were greatest at the sites with higher water use efficiency for each location.
