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!

                Floridan Aquifer Collaborative Engagement for Sustainability (FACETS) - Field trial data from Live Oak, Florida: ARDN products

                  ARDN (Agricultural Research Data Network) annotations for "Floridan Aquifer Collaborative Engagement for Sustainability (FACETS) - Field trial data from Live Oak, Florida". The ARDN project (https://data.nal.usda.gov/ardn) is a network of datasets harmonized and aggregated using a common vocabulary termed ICASA. ICASA is a recommended data dictionary by USDA NAL (https://data.nal.usda.gov/data-dictionary-examples) described in detail here: www.tinyurl.com/icasa-mvl. Research was conducted at the North Florida Research and Education Center - Suwannee Valley, located near Live Oak, Florida (30°18’22” N, 82°54’00” W). Corn, carrots, peanuts, and rye (cover crop) were grown on Hurricane, Chipley, and Blanton soil complexes that are all over 90% sand. The experimental design utilized a randomized complete block design with split plot that incorporated two fields with eight blocks (treatment replicates) and fifteen plots per block. The main plots contained four irrigation treatments, and the sub-plots contained three different nitrogen rates. The SMS irrigation treatment contained three additional nitrogen treatments. The north field in the study (System 2) was a corn-cover crop-peanut-cover crop rotation, while the south field (System 1) was a corn-carrot-peanut-cover crop rotation. During each growing season, soil moisture was monitored using capacitance type soil moisture sensors, soil nitrogen was measured through bi-weekly soil samples at four depths, and biomass was collected four times with the final sample being collected just prior to harvest.
