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.
