To economically, increase cereal crop yields on poor performing sand rises incorporating chicken manure at sowing in the in cropping paddocks.
The trial went well in 2011 because the manure coverage was good. Michael was disappointed with the results from the deep rip treatments with or without lime, because there was no significant yield difference compared to the control and hence no economic gain. However applying chicken manure at 2t/ha resulted in an increase in yield (especially from the most acidic sand rises) with a considerable economic gain/return. Therefore, as a result of these trials Michael is going to implement a strategic manure application programme with the objective of increasing his paddocks yield and profitability while reducing the impact of the sand rises. Fellow growers in the area have embraced the trial outcomes and most of them are keen to adopt a similar strategy in their cropping system since chicken manure is widely available in the area.
