Reviving historic crop trial data

The data

The University of Adelaide (UoA) were interested in using Waite Permanent Rotation Trial datasets (1925 – 1993) to investigate the interaction of genotype, environment and management over the past decades with the possibility of using this historic data in predictive crop modelling.

 

The challenge

Although The Waite Trial datasets were publically available, the data was stored as individual MS Excel files and sometimes data was color coded. This made it difficult to reuse and combine with other data for predictive crop modelling.

The solution

With the support of AgReFed partners, UoA researchers worked together with their library and IT support to bring together and deliver the Waite Trial dataset in a standard format.

 

  • The Waite Permanent Rotation Trial legacy data was converted from multiple MS Excel worksheets into a consistent and structured format (MySQL database) 
  • Meaning was added to the data by using machine-readable agricultural terms and standard terms (such as 'units of measure') with the assistance of Research Vocabularies Australia  support staff
  • The data is hosted at Pawsey Supercomputing Centre, and is accessible through AgReFed via PostgREST API
 

Both Researchers and machines can now access and understand the Waite Trial dataset, search the parameters of interest within these datasets (including across a specified period of time), and access the data in analysis-ready format.

 

The impact

Research insights

The Waite Historical Permanent Rotation Trial datasets (1925 – 1993) are available as they never have been before. 

Researchers can now search and filter the variables of interest. Importantly, they will also know what the data means, since it is described with permanent web addresses leading to standard agricultural descriptions (controlled vocabularies).

The historic trial data  is now accessible in analysis ready formats through AgReFed, including in machine readable format.  It is reusable for predictive crop modelling under future climate and management scenarios, for example through integrating with climate data.

Postdoctoral Fellow Dr Rakesh David states that he could

“assess the FAIRness of other data sets are now”, and “understands the components required to make data accessible”. 

Rakesh now

“knows how to go about applying vocabularies”  and “will attempt to apply known standards to future reseach datasets” .

 

The future

The UoA team hope to continue to collaboate with crop researchers through AgReFed do deliver and describe crop trial data in a standard way.

 

By working on this together, researchers will be able to combine their datasets for more powerful predictions of crop success under future climate and management scenarios.
