Project Overview
What’s Holding Your Crop Back?
Poor crop performance in Mallee paddocks often results from a range of interacting soil constraints across different soil types, including sandy rises, calcareous soils, red-brown earths, shallow soils over calcrete, and heavier subsoil layers. These constraints can affect crop establishment, root growth, water use, and nutrient uptake, with common issues including water repellence, low fertility, compaction, high soil strength, alkalinity, salinity, sodicity, boron toxicity, chloride toxicity, subsoil carbonate, and erosion risk.
Effective management starts with correctly identifying the main constraint within the target zone of the paddock before selecting a treatment. This is important because the most appropriate response depends on whether the limitation is physical, chemical, nutritional, or a combination of factors.
