In June, I attended a conference called Driving Innovation through Data in Agriculture. It was an enjoyable and interesting experience, combining researchers and librarians onsite at the National Agricultural Library (NAL). There were several things that I brought back with me for further discussion. One of them was that I learned quite a bit about the different agriculture specific databases that the USDA manages. They are all public and provide different specialty products and can be accessed through the National Agricultural Library website. The NAL is responsible for building an integrated portfolio of knowledge products that can be used by the general public, researchers and those working in agriculture.
The Long-Term Agroecosystem Research Data Overview (LTAR) database publishes the data and information generated through the Long-Term Agroecosystem Research (LTAR) Network, a partnership of 18 research sites across the United States. They focus on building knowledge that will make agriculture sustainable and examining the environmental impacts of farming practices. The data generated is “Common Observatory Data” or CORe observational data and research data from management studies with crops and livestock. It compares current practices to experimental practices to determine the effects of the changes. Available data types from LTAR include site photographs, weather and aerial images for the research stations as well as data sets and reports published by LTAR. It has an average of 50 years of historical data. LTAR maintains the data to be sure that it is FAIR: Findable, Accessible, Interoperable and Re-usable. It is hosted at the Ag Data Commons repository and the Geospatial Platform. The Ag Data Commons is the central registry for USDA data and provides links to any data that is housed outside of the repository, including data that is first uploaded to agency sites and provides citable DOI’s for each dataset. The Geospatial Platform provides curation for GIS data but is cross referenced and linked with both Ag Data Commons and Data.gov, the government’s one stop shop for all government sponsored data.
Some of the other specialized USDA data bases include the Life Cycle Assessment Commons, USDA Food Composition Database, the i5 Workspace@NAL, which is a community specializing in arthropod genomes and research and Dr. Duke’s Phytochemical and Ethnobotanical Databases. Less specialized databases include the NAL catalog which covers the entire NAL collection, AGRICOLA, PubAg and NAL Digital Collections, which includes all the full text digitized materials of NAL.
I hope researchers, faculty and students will explore some of these. I would be interested to hear about any projects that utilize them. We here in the library are discussing the use of these specialized databases versus the more popular, general use ones. Feel free to post any examples and please, contact me or any of our friendly librarians if you need more information.
