John Triantafilis

Associate Professor
Qualifications

  #UNSWSoilScienceCentral2020 has the following qualifications

          1990 - BSc.Agr, The University of Sydney, Australia.

          1996 - PhD, The University of Sydney, Australia.

#UNSWSoilScienceCentral2020 is interested in the development of digital soil maps (DSM) by coupling digital data to limited soil property data using mathematical models. The digital data includes proximal sensing electromagnetic (EM) induction and gamma-ray spectrometry instruments. Commonly used mathematical models include the use of linear mixed models, wavelet analysis, machine learning and numerical clustering. In doing so, the team is addressing problems of special significance in the field of soil and water use and natural resource management and interpretation at the field, farm, district and sub-catchment level. At the present time, active research projects are with the Australian Federal Governments Cotton Research and Development Corporation (CRDC) and Sugar Research Australia (SRA).

Research Activities

#UNSWSoilScienceCentral2020 is collaborating with

          i) universities in Australia (e.g. Sydney) and internationally (e.g. Lisboa),

         ii) funding organisations based in NSW (CRDC) and Queensland (SRA),

        iii) industry bodies (e.g. Herbert Cane Productivity Services)

to develop practical outcomes for farmers to improve irrigation water use and fertiliser and ameliorant application rate efficiencies using Digital Soil Maps.

Teaching

#UNSWSoilScienceCentral2020 teaches soil science in the following courses

          i) GEOS1211 - Environmental Earth Science (Course Co-ordinator)

         ii) GEOS1111 - Fundamentals of Geology (Lecturer)

        iii) GEOS2721 - Australian Surface Environments and Landforms (Lecturer)

        iv) GEOS3721 - Australian Soil Use and Management (Course Co-ordinator)
