Amelioration strategies for non-wetting gravel soils in a high rainfall area locations
Aims

To trial a range of non-wetting treatments on non-wetting forest gravel soils in the south west, in a high rainfall area, to determine which, if any, will increase water penetration and what soil characteristics have altered as a result of the treatment.

Key messages

Most treatments that altered the wetting properties of the soil improved the grain yield also. The mould board ploughing treatment was an exception due to the introduction and inter-locking gravel in the topsoil which might have impeded the germination. Once established the crop on the ploughed plots did very well. None of the treaments were able to economically improve the yield because the Control plots yielded exceptionally well.
