Extension of amelioration methods to address non-wetting soils in Albany and Kwinana West zones: Erin Cahill - On-farm results summary locations
Aims

To assess the value of spading on deep yellow sandplain and additional advantages that may come from the ability of spading to incorporate lime and nutrients into the subsoil.

Key messages

Report: Erin Cahill - on-farm results summary: Soil water repellence is relatively easy to diagnose but because numerous soil types can be affected and there are many possible management options deciding how best to address the problem can be difficult. Deciding on a water repellence management strategy in cropping systems will be determined by many factors including: the severity of the water repellence, soil types affected, how much of the farm is affected, impact of other constraints and whether repellence occurs in discrete patches or larger more widespread areas.
