Catalogue: GRDC Updates
Subsoil constraints limit the ability of roots to extract water from the soil and often decrease yield, especially where in-crop rainfall is poor... At Spring Ridge in 2006, we found that Ripper canola outyielded Rivette at both trial sites, but it was the reverse at Bellata in 2005, and no different at any Garah trials... The observation suggests that potential yield advantages of improved varieties seen at the unconstrained site were nullified by the subsoil constraining access to available soil water at the poor site...

The occurrence of high levels of salts, sodium and chlorides (Cl) in the northern grains region subsoils effectively reduces rooting depths, increases osmotic potential and chloride toxicity, and reduces the crop water use from the soil profile... The Decision Tree and toolkit developed in this project have become essential components of identifying and managing subsoil constraints (SSC) for advisers and growers... More recent research was carried out in project DNR00008 Advanced Techniques for Managing Subsoil Constraints...
