Digital soil mapping of soil carbon at the farm scale: A spatial downscaling approach
Initiated during 2015, Quentin Styc was a visiting intern student from France to our soil security laboratory for 3 months. I had this idea of spatial downscaling and trying to include observational data into the scheme. Quentin was happy to work on this little problem, and actually presented some preliminary results on this at the…

Geochemical fingerprinting of volcanic soils used for wetland rice in West Sumatra, Indonesia
Toward the end of 2016, Prof. Dian Fiantis (Department of Soil Science, Faculty of Agriculture, Universitas Andalas, Kampus Limau Manis) spent around 3 months in our soil science research group. With her in her kit bag, were a number of soil samples collected from various sites around a few different volcanoes situated in West Sumatra,…

Rapid assessment of petroleum-contaminated soils with infrared spectroscopy
This is the first paper from our new PhD student in the Soil Security Laboratory, Wartini Ng. Soil sensing using infrared spectroscopy has been proposed as an alternative to conventional soil analysis to detect soil contamination. This study evaluated the use of field portable and laboratory bench top infrared spectrometers in both the near infrared (NIR)…

Soil spectral inference workshop at RDA, Korea
I requested Dr. Budiman Minasny to conduct the soil spectral inference workshop at RDA National Academy of Agricultural Science, Suwon in February 2013. RDA has a laboratory with near infrared spectroscopy for measuring soil reflectance. However its use is not optimized because the processing of the spectral data require advanced statistical analysis. Dr. Minasny has…

Sydney Soil Schools Intensive Digital Soil Mapping Workshop in Vancouver, Canada
Between January 24-27, 2017 the Sydney Soil Schools team were situated in Vancouver, Canada providing an intensive hands-on workshop in digital soil mapping. The team consisted of Prof. Alex McBratney, Prof. Budiman Minasny and Dr. Brendan Malone. They were invited by the Canadian Government, whom recently have embarked on a national project of the digital…

This book entitled Using R for Digital Soil Mapping is an excellent book that clearly outlines the step-by-step procedures required for many aspects of digital soil mapping. This is my first time to learn R language and spatial modelling for DSM, but with the instructive book, it’s easy to produce different DSMs by following text…

Welcome to the Digital Soil Century
Digital soil mapping is a runaway success. It has changed the way we approach soil resource assessment all over the world. New quantitative DSM products with associated uncertainty are appearing weekly. Many techniques and approaches have been developed. We can map the whole world or a farmer’s field. All of this has happened since the…
