Large barley yield responses four years after soil inversion on highly repellent pale deep sand locations

To assess the impact of mouldboard ploughing and clay spreading on soil water repellence and grain yield.

Key messages
  • The one-off 2010 mouldboard ploughing treatment has resulted in yield increases of 1.0 t/ha or more for the past 4 seasons.
  • The measured yield increases were partly a result of overcoming the water repellence by soil inversion and improving crop establishment.
  • For further details please see attached trial report.

Soil amelioration

2010 – mouldboard ploughed 5 ha

2012 – mouldboard ploughed a further 30 ha in the trial paddock 2012 – clay strips 150 t clay-rich subsoil/ha

2012 – combined treatments included a strip of clay spread on top of part of the 2010 mouldboard ploughing (Mouldboard 2010 + Clay) or an area of spread clay that was then inverted into the subsoil using a mouldboard plough (Clay + Mouldboard 2012).
