• The early results of this project showed great potential in improving soil structure and crop productivity in sodic subsoils using deep placement of organic and inorganic amendments. The increases resulted from improvement in the physical and chemical properties of the clay soil volume around the rip line containing the organic and inorganic amen...

• Like El Nino and La Nina, the Indian Ocean Dipole (IOD) is a major contributor to climate variability in south east (SE) Australia. • The IOD is a coupled phenomenon where the ocean and the atmosphere feed off each other’s behaviours. • The IOD strongly effects the north west (NW) cloud band activity feeding in from over Broome. • Positive IOD (+...

• Management of hard to control weeds requires an understanding of when the weeds germinate. • High efficacy is needed with the first herbicide mixture to achieve good double knock control of fleabane in summer. • Windmill grass needs to be controlled as soon as it is noticed, as the old plants are much harder to control. • Early autumn application...
