This Grains Research and Development Corporation (GRDC) book provides guidance on improving sandy soils using clay-rich subsoils in Western and South Australian farming systems. Sandy soils can be difficult to manage due to low water-holding capacity, inherently low fertility, pH constraints, limited biological activity, and susceptibility to wind erosion. Many are also water repellent. #
Research and field experience show it can be feasible and profitable to increase soil clay content to above five per cent. However, success depends on applying the correct rate of clay and understanding the chemical properties of the subsoil being used. The book outlines practical approaches for implementing effective claying programs and includes 8 grower case studies. While focused on Western and South Australia, the findings are also relevant to similar sandy soils in Victoria and New South Wales. #
