    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).

    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).

      2017 Census of Agriculture - Census Data Query Tool (CDQT)

        The Census Data Query Tool (CDQT) is a web-based tool that is available to access and download table level data from the Census of Agriculture Volume 1 publication. The data found via the CDQT may also be accessed in the NASS Quick Stats database. The CDQT is unique in that it automatically displays data from the past five Census of Agriculture publications.

        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.

            2012 Census of Agriculture - Web Maps

              The Census of Agriculture provides a detailed picture every five years of U.S. farms and ranches and the people who operate them. Conducted by USDA's National Agricultural Statistics Service, the 2012 Census of Agriculture collected more than six million data items directly from farmers. The Ag Census Web Maps application makes this information available at the county level through a few clicks. The maps and accompanying data help users visualize, download, and analyze Census of Agriculture data in a geospatial context.
