His main research interests are in plant-plant and plant-microbial interactions and weed management using non-herbicidal strategies. Saliya is currently investigating the use of cover crops and mulches to suppress key agronomic weeds in the Eastern grain growing region of Australia, in a Grains Research and Development Corporation invested project. He is also associated with various research projects funded by the Australian Department of Agriculture, Fisheries and Forestry, investigating the role of cover crops to improve soil health and the impact of dung beetle activity on soil fertility and nutrient cycling.
