My research interests include the development and application of ground-based Electromagnetic (EM) induction methods to generate natural resource information for improved soil and water management in irrigated cotton growing areas. In order to facilitate this research, and ensure it addresses natural resource management issues, I have actively collaborated with a number of community groups, including:
- Macintyre River Food and Fibre,
- Gwydir Valley Irrigators Association, Coordinating Committee of Namoi valley water users association,
- Macquarie 2100 and
- Darling River Food and Fibre.
The main aim of my research is focused on using geostatistical methods to supplement limited soil survey information in combination with ground-based geophysical instruments (i.e. EM) and satellite data.
Their application to produce biophysical data ( e.g. agronomy, geology, topograrphy, hydrology and climate) can be used to ascertain where soil and water salinisation may occur. At the field level I developed a Mobile Electromagnetic Sensing System (MESS) for field-scale investigations of soil salinity and irrigation efficiency assessment. At the district level (20,000-200,000 ha) I am developing EM surveys and soil sampling schemes to map groundwater recharge rate, identify deep drainage risk areas, and locate subsurface saline material.

This web-based Geographic Information System (GIS) allows stake holders (e.g. cotton growers, farm managers, consultants) access to digital biophysical data collected as part of a series of Cotton Research and Development Corporation and Natural Heritage Trust projects.
