Report for irrigated acres in the open. For each irrigated crop in the open, report separately the prinnary field distribution 
method, acres irrigated by water source, and acres on which chemigation was used in the irrigation system. Refer to the 
table above for the water distribution I .D. codes.

^ On-farm water source includes recycled water and reclaimed water from on-farm livestock operations. 
^ Off-farm water supplies may include water purchased from the U.S. Bureau of Reclamation; a State, county, or local district; mutual, private, cooperative, or 
neighborhood ditches; or commercial or municipal water systems.
