The trial was designed to investigate a range of techniques that may improve crop establishment and performance on non wetting sandy soils. The techniques tested included mouldboard ploughing, winged knife points, and H2O Lure. The trial also compared the second year affect of mouldboard ploughing to first year response..
Mouldboarding was the driver of crop yield in the trial with 2012 mouldboard treatments producing, on average, 85% higher yielding than no mouldboard. The 2011 mouldboard treatments were on average 44% higher yielding than no mouldboard.
