ARDN

About the The Agricultural Research Data Network (ARDN)

ARDN is a network of datasets which can be harmonized and aggregated using a common vocabulary and format through the use of annotations. Datasets in ARDN are connected by a common protocol for annotating data which allows these datasets, in their raw format, to be interpreted in an automated way. The goal of ARDN is to create a distributed network for harmonized crop systems research data and to make these data available through existing data portals such as USDA’s Ag Data Commons and CGIAR’s GARDIAN.

ARDN data providers have data that they wish to make available to researchers in a format that can be interpreted in an automated way. ARDN tools assist these users to “ARDN-ize” their data thereby making these datasets reusable. End users of ARDN data make use of the interoperability of these datasets and can download, combine, and transform the data into formats that can be used in modeling applications, data analytics, meta-analyses, and other quantitative uses. Currently ARDN contains mainly agronomic research data and does not (yet) include data from other agricultural domains such as livestock, pest and diseases, aquaculture, socioeconomics, or genetics. ARDN is mainly developed for quantitative data that are used in modeling and analytics. We hope that in the future, datasets are collected from the field using standardized vocabularies and ontologies so that the ARDN data annotation method is no longer needed. But until then, we offer these interoperability hacks!

    ARDN Datasets

    8 datasets

    Sustainable Corn CAP Research Data (USDA-NIFA Award No. 2011-68002-30190): ARDN Products

      ARDN (Agricultural Research Data Network) annotations for Sustainable Corn CAP Research Data (USDA-NIFA Award No. 2011-68002-30190). These data are a subset of the Sustainable Corn CAP (Cropping Systems Coordinated Agricultural Project: Climate Change, Mitigation, and Adaptation in Corn-based Cropping Systems) data specifically developed for Agricultural Research Data Network with csv and json files for easy ingestion into crop models.

This data was collected and published by University of Georgia's Statewide Variety Testing program from 2014-2019. It consists of experimental (non-regulated) and commercially-released corn hybrids entered by seed companies.

          UGA Variety Testing Soybean Evaluations 2016-2019: ARDN products

            ARDN (Agricultural Research Data Network) annotations for UGA Variety Testing Soybean Evaluations 2016-2019. This data was collected and published by University of Georgia's Statewide Variety Testing program from 2016-2019. It consists of experimental (non-regulated) and commercially-released soybean germplasm entered by seed companies, universities and USDA breeding programs.

            TERRA-REF Season 6 phenotypes and agronomic metadata in BrAPI format

              This data represents a small subset of the TERRA-REF release available on Dryad (LeBauer et al 2020), including harvested biomass for each cultivar, plot location, planting date, harvest date, fertilizer application, genotype / accession names and metadata, and additional agronomic management metadata for a population of Sorghum bicolor evaluated over two growing seasons. The data can be accessed through a BrAPI-compliant endpoint at terraref.org/brapi. This dataset is a snapshot of the TERRA-REF BrAPI endpoint contents, representing the minimum data and metadata required to run a crop model.
