The 2016 Bioprime trial at the WMG site was conducted to investigate the interactions of Bioprime application with in-furrow liquid fertiliser compared to conventional granular fertiliser, and their effects on plant growth and grain yield. Bioprime was added as a seed dressing (2 L/t seed), and/or as a post emergence spray (4 L/ha). This is the fifth of Bioprime field trials (three previous years with Liebe Group at Buntine and at Forrestdale with different crops). West Midlands Group (WMG) trial design in 2016 was replicated exactly at the Liebe Group and to some extent at Forrestdale in 2016.
This trial was implemented in 2015 to determine which ameliorant practice is the most effective and economic in remediating subsoil acidity at depth. The trial consists of four replicates of different mixing (untreated, spaded, grizzly) with products applied (untreated, lime, dolomite and lime and dolomite). This trial was designed by a project committee of Liebe members to determine the most effective liming strategy to maximise the return on investment in the Liebe region. The trial was located west of Wubin on a poor performing paddock that has the potential to improve once subsoil constraints have been addressed.
