The Busselton-Marybrook Grower Group formed in 2014 with a shared vision to improve the quality of their potatoes. Group members believe potato quality is linked to soil health, which is linked to plant stress and exposure to disease.
Over the past four years the group has partnered with Murdoch University and the South West Catchments Council (SWCC), through funding from the Australian Government’s National Landcare Program, to trial high-biomass cover crops aimed at increasing soil carbon, the measurable component of soil organic matter and a key indicator of soil health.
Growing high-biomass cover crops requires attention to fertiliser programs and potentially irrigation. The best variety of cover crop for a particular soil type and climate must also be selected. Also, cultivation needs to be rationalised to ensure that gains in carbon from cover cropping are not lost through over-cultivation.
If cover crops and cultivation can be well managed, it is possible that soil structure can be improved.
