Over the past five years considerable research has been undertaken assessing options for water repellent sands but less has been done for the gravel soils. The aim of this research is to look at soil water repellence management options for sandy gravel soils over a four year period (until December 2018). This research consisted of on-farm strip trials comprised of five different treatments for water repellence (Control, Paired row, minimal disturbance and two types of wetting agents) in combination with two cultivation treatments (modified one-way plough or no plough). The first year study showed that the adoption of a strategic tillage practice (one-way plough) provided a significant improvement in terms of crop establishment and grain yields on a moderately repellent sandy gravel.
