To demonstrate different methods to retain stubble for soil moisture retention.
• The economic analysis showed there were a number of low and high-cost options for stubble retention which provide alternatives to burning.
• A high liming rate of 6.7t/ha was applied across the demonstration to address the acidity in the 5-15cm layer of soil.
• The liming increased the 0-10cm pH across all treatments increased to pH 5.8 or higher, which is the target level of pH to address subsurface acidity.
• The 10-20cm pH results for the unincorporated lime treatments were not consistent with current research and require further investigation.
