The Ag Data Commons is migrating

The Ag Data Commons is migrating to a new institutional portal on Figshare. The current system is available for search and download only. The new platform is open for submission with assistance from Ag Data Commons curators. Please contact NAL-ADC-Curator@usda.gov, if you need to publish or update your datasets.

Unit Process for Wood Chip Briquette Production, 2016

    This unit process dataset represents the production of 1 dry ton of wood chip briquette from wood chips using RUF200 model briquette (RUF Briquetting Systems, Zaisertshofen,Germany) in Big Lagoon, California. Additional details on the process can be found in Alanya-Rosenbaum et al (2018). Briquettes are produced using RUF200 model briquetter (RUF Briquetting Systems, Zaisertshofen,Germany), which uses dried woodchips generated from forest residues as feedstock. Capacity of 200 kg/hr.

    Unit Process for Torrefied Wood Chips, 2016

      This unit process dataset represents the production of 0.0436 oven-dried kg (1 MJ) of torrefied chips at torrefier (Biogreen, ETIA Group, Compiègne, France, and Norris Thermal Technologies, Tippecanoe, Indiana, USA) at Samoa, California. Additional details on the process can be found in Alanya-Rosenbaum et al (2018).

      Product System Model for Beef Production 2011

        Product system boundaries (cow-calf-finisher, CCF) include all material and energy flows associated with crop production and live cattle operations. Cattle inventory flows include the cow-calf operation and end with market weight finisher cattle and culls resulting from one full year of operation. The total live weight produced in one year is 2914841.44 kg and is comprised of the following animals: Finished cattle: 3724 (581 kg/finisher), Culled cows: 1156 (636 kg/cow), Culled bulls: 58 (908 kg/cow). These data were developed using Integrated Farm System Model and are intended to represent the MARC cattle operation in Nebraska in 2011. The data were a product of a project funded by the National Cattleman's Beef Association.

        Land Use Strata - Selected States

          The United States Department of Agriculture (USDA), National Agricultural Statistics Service (NASS) area sampling frame is a delineation of all parcels of land for the purpose of later sampling the parcels. The area frame is constructed by visually interpreting satellite imagery to divide a state into homogenous land use areas (strata) based on percent cultivated. The strata are typically defined as low, medium or high percent cultivated, non-agricultural land, urban use, agri-urban, or water. This site provides links to download ESRI shape and symbology layer files, as well as low resolution JPEG or higher resolution PDF images for each state.

          Unit process data for lignin extraction in a softwood kraft pulp mill

            This unit process represents the gate-to-gate production of 1 air-dried metric tonne of kraft lignin, coproduced with southern bleached softwood kraft pulp (SBSK), high voltage electricity and unrefined tall oil soap. The pulp is derived from pine or loblolly pine in a kraft pulping process at a mill in the southern United States (U.S.). Lignin is extracted via precipitation and acid washing. All flows are production weighted to kraft lignin. The SBSK pulp production technologies are an aggregation of those applied in the southern U.S. in 2013.
