Innovations in cropping systems - a step change towards sustainable soil management across Victoria's grain growing regions

Given that water is the principal limiting factor in rain-fed cereal production in Victoria, practices that improve water capture, storage and use are required. Improvements in soil condition in agriculture, through the adoption of innovative practices has the potential to increase production, water use efficiency and environmental sustainability, while also addressing the growing challenges of climate variability. The response of subsoil manuring (SSM) and controlled traffic farming (CTF) on improving severe subsoil constraints, including compaction, sodicity and high soil strength, was investigated in cropping enterprises in the low to medium rainfall zones of Victoria. Despite experiencing below average rainfall conditions in both years of the project (2014 and 2015) there were encouraging responses of increased crop yield and reduced soil compaction across some sites and innovations. Partnerships and engagement with farmers is important for driving practice change, by demonstrating innovative practices locally and having leading farmers mentoring other farmers.
