My role in the department

Dr Davies has expertise in managing soil constraints in cropping systems with a focus on developing practical tools and options for grain growers. He leads two DPIRD and GRDC funded co-investment projects. Outcomes from these projects include: 1) Optimising management of multiple interacting constraints across variable soils and test the value of re-engineering soil profiles to 80cm+. 2) Optimise amelioration timing, seedbed preparation, herbicide use and crop rotations to maximise the size and longevity of amelioration benefits.
