Unit process data for field crop production version 2

    The goals for the release of Version 2 of the field crop data are to rework the data to link up with the tier 2 field operations/ work process datasets, eliminate the use of service processes, and rework balance parameters using a simpler formula. Models represent states that produced field crops in the ARMS survey years included.

    Unit process data for field crop production version 1

      These unit process models represent crop production in US states in multiple years. The main data source used for the development of the field crop data described here is the annual USDA Agricultural Resource Management Survey (ARMS). ARMS data are from an annual national survey of field-level farm practices sponsored jointly by USDA Economic Research Service (ERS) and the USDA National Agricultural Statistics Service (NASS). These datasets were released in ecospold version 1 in June 2012.
