Process Name operation of Field cultivator (Cultivator, field 6-12 in sweeps); for growing oats; at farm; 260HP tractor, 42 ft wide
Category Agriculture, forestry and fishing - ISIC 0161: Support activities for crop production
Location US-AZ
Geography Comment The process is assumed to be operated in the State of Arizona.
Quantitative Reference operation of Field cultivator (Cultivator, field 6-12 in sweeps); for growing oats; at farm; 260HP tractor, 42 ft wide
Start Date 2014-01-01
End Date 2014-12-31
Date description Start and end dates were chosen to match the equipment data in the USDA LCA Commons.
Technology Description Data for 1 ha represent 1 pass for the implement. Included processes are implement construction, operation, storage, the use of spare parts, and retirement. All flows are to or from the technosphere.


Process Type UNIT_PROCESS
Data completeness To the best of the knowledge of the authors, all intermediate flows are accounted. There are no flows to or from the environment.
Data treatment Data development is demonstrated by parameterization (explicitly presents raw data and calculations). Flow data quality is presented according to the LCA Commons convention as described in Cooper, J.S., E. Kahn, Commentary on issues in data quality analysis in life cycle assessment. International Journal of Life Cycle Assessment 17(4) 499-503 (2012).
Sampling procedure Boundary conditions are defined to represent typical operations for the crop and at the state level. Uncertainty and variability are not considered.
Data collection period Unit process data were compiled from 2013-2015.
