Testing for disease suppressive soils

Branding Community Sourced

Amanda Cook, Senior Research Officer with SARDI at the Minnipa Agricultural Centre on the upper Eyre Peninsula, discusses her disease suppressive soils research. A disease suppressive soil is the ability of the microbial population in the soil to inhibit fungal root diseases, especially Take-all and Rhizoctonia. A rotation trial was established on a grey calcareous soil at Streaky Bay in 2004 to determine if disease suppression could be achieved on these soils types. This research was conducted as part of the projects “Managing root diseases on upper Eyre Peninsula through disease suppression S3/05” and “Developing robust and lower risk farming systems by understanding the impact of soil carbon S0108R”, funded by South Australian Grains Industry Trust (SAGIT) with support from the Eyre Peninsula Agricultural Research Foundation (EPARF).
