Amelioration of hostile subsoil in high rainfall south-west Victoria locations
Aims

Experiments were conducted on two different soil types to test if (a) amelioration of these subsoils with a mix of gypsum and organic peat would increase the ability of the soil to hold more ‘plant available’ water and (b) if this extra water availability, would assist crops to achieve a better yield.

Key messages

Two rates of ameliorants were applied. Data collected in early Spring showed that both treatments led to increased soil water at varying depth in soil compared to the control. Different soils responded differently.
