Description
Soil water repellence represents one of the major soil constraints to broad-acre agriculture in southern Australia. Topsoil wettability is significantly reduced by the presence of hydrophobic organic compounds, resulting in poor seed germination, early plant establishment and ultimately lower yields. Soil mechanical disturbance (tillage) in combination or not with the addition of clay-rich subsoil (e.g. clay spreading) have been successfully adopted in the Australian broad-acre agriculture for the amelioration of water repellent sandy soils.
