Research & Current Projects
 

#UNSWSoilScienceCentral2019 is interested in the development of digital soil maps (DSM) by coupling ancillary information to limited soil property data using mathematical models.

 

We collaborate with universities in Australia (Sydney, Monash and UWA) and internationally (Lisboa, Cordoba, Aarhus, UCRiverside and UWisconsin-Madison). We are ready, willing and able to work with you too! 

 

We are currently “hardly” working on applying DSM methods to irrigated cotton growing areas of northern New South Wales and in sugarcane growing areas in far north Queensland.

The work is funded by the Australian Federal Governments Cotton Research and Development Corporation and Sugar Research Australia.

 

 

In terms of ancillary data, we use visible near infra-red spectrometry information with soil properties to predict these across large irrigated cotton growing areas.

We are currently developing calibration models (using cubist) to predict clay, CEC and O.M. in cotton growing areas and sugarcane farms in far north Queensland.

 

 

We also are interested in using electromagnetic (EM) induction instruments, like the state of the art DUALEM-421 to make 2-d and 3-d models using cutting-edge inversion software.

Current work aims to predict soil properties including salinity and clay and to monitor soil moisture, at various scales field, farm and district scales.

 

 

Research is also ongoing in the use of gamma-ray spectrometry data to help develop DSM to map either individual soil properties (CEC) or identify management zones.

The results can then be used for precision application of fertilisers and according to six-easy-steps Nutrient Management Guidelines in sugarcane fields.

 

terraGIS

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.
