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...
