Host: GGA Grains Research, Development and Extension Communications Manager, Amber Atkinson
Guest Speaker: DPIRD Research Scientist, Tom Edwards
In this episode DPIRD Research Scientist Tom Edwards explains the research he is undertaking in soil management to boost grains productivity.
Tom is assisting with a series of trials to help growers manage soil constraints like acidity, compaction, water repellence and herbicide-resistant weeds.
His focus is on mechanical soil amelioration, which includes common techniques include soil mixing, (e.g. ripping and spading), soil inversion (e.g. mouldboarding or one-way plough) and deep ripping, all of which lead to various degrees of soil mixing, creating a changed soil profile.
Tom explains some of the main barriers to adoption and what he is aiming to achieve in his trials.
